1.建立一个web项目

2.导入SSH框架所需jar包

3.配置web.xml文件


     
       
      
       SSHDemo
          
        
          
       
        login.jsp

        default.jsp
         
          
        
        
           
       
        contextConfigLocation
           
           
       
        classpath:applicationContext.xml
         
          
        
          
       
                    org.springframework.web.context.ContextLoaderListener    
         
          
        
          
       
        OpenSessionInViewFilter

        struts2
           
       
                    org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter        
         
          
        
          
       
        struts2
           
       
        /*
         
          
        
          
       
        25

4.配置applicationContext.xml文件


     
         
          
          
          
              
               
               
               
               
               
               
               
               
           
              
          
              
               
                   
                
               
               
                   
                        
                         
         
                              org.hibernate.dialect.MySQLDialect                
                         
                         
         
          true
                         
                         
         
          true
                     
                
               
               
                   
                        
         
          classpath:com/sshdemo/entity/

5.建立实体类及其对应的xml文件

package com.sshdemo.entity;/** * 员工 实体类。  */public class Employee implements java.io.Serializable {    // Fields    private static final long serialVersionUID = 5106663630382037556L;    private String sn;    private Position position;    private Department department;    private String password;    private String name;    private String status;    // Constructors    /** default constructor */    public Employee() {    }    /** full constructor */    public Employee(Position position, Department department, String password,            String name, String status) {        this.position = position;        this.department = department;        this.password = password;        this.name = name;        this.status = status;    }    // Property accessors    /**     * @return 工号     */    public String getSn() {        return this.sn;    }    public void setSn(String sn) {        this.sn = sn;    }    /**     * @return 职务     */    public Position getPosition() {        return this.position;    }    public void setPosition(Position position) {        this.position = position;    }    /**     * @return 部门     */    public Department getDepartment() {        return this.department;    }    public void setDepartment(Department department) {        this.department = department;    }        /**     * @return 密码     */    public String getPassword() {        return this.password;    }    public void setPassword(String password) {        this.password = password;    }        /**     * @return 姓名     */    public String getName() {        return this.name;    }    public void setName(String name) {        this.name = name;    }        /**     * @return 状态     */    public String getStatus() {        return this.status;    }    public void setStatus(String status) {        this.status = status;    }}

创建employee对应的xml文件：Employee.hbm.xml

创建部门的实体表和xml文件

package com.sshdemo.entity;/** * 部门 实体类。  */public class Department implements java.io.Serializable {    // Fields    private static final long serialVersionUID = 5073258499319872911L;    private Integer id;    private Employee manager;    private String name;    // Constructors    /** default constructor */    public Department() {    }    /** minimal constructor */    public Department(String name) {        this.name = name;    }    /** full constructor */    public Department(Employee manager, String name) {        this.manager = manager;        this.name = name;    }    // Property accessors    /**     * @return 部门编号     */    public Integer getId() {        return this.id;    }    public void setId(Integer id) {        this.id = id;    }        /**     * @return 部门经理     */    public Employee getManager() {        return this.manager;    }    public void setManager(Employee manager) {        this.manager = manager;    }        /**     * @return 部门名称     */    public String getName() {        return this.name;    }    public void setName(String name) {        this.name = name;    }}

创建Dictionary

package com.sshdemo.entity;/** * 数据字典 实体类。  */public class Dictionary implements java.io.Serializable {    // Fields    private static final long serialVersionUID = -3482598030856972288L;    private long id;    private String type;    private String item;    private String value;    // Constructors    /** default constructor */    public Dictionary() {    }    /** full constructor */    public Dictionary(String type, String item, String value) {        this.type = type;        this.item = item;        this.value = value;    }    // Property accessors    /**     * @return 编号     */    public long getId() {        return this.id;    }    public void setId(long id) {        this.id = id;    }    /**     * @return 类型     */    public String getType() {        return this.type;    }    public void setType(String type) {        this.type = type;    }    /**     * @return 条目     */    public String getItem() {        return this.item;    }    public void setItem(String item) {        this.item = item;    }    /**     * @return 值     */    public String getValue() {        return this.value;    }    public void setValue(String value) {        this.value = value;    }}

创建positon类和xml

package com.sshdemo.entity;/** * 职务 实体类。  */public class Position implements java.io.Serializable {    // Fields    private static final long serialVersionUID = 4107962667586915867L;    private Integer id;    private String nameCn;    private String nameEn;    // Constructors    /** default constructor */    public Position() {    }    /** minimal constructor */    public Position(String nameCn, String nameEn) {        this.nameCn = nameCn;        this.nameEn = nameEn;    }    // Property accessors        /**     * @return 职务编号     */    public Integer getId() {        return this.id;    }    public void setId(Integer id) {        this.id = id;    }    /**     * @return 职务名称（中文）     */    public String getNameCn() {        return this.nameCn;    }    public void setNameCn(String nameCn) {        this.nameCn = nameCn;    }    /**     * @return 职务名称（英文）     */    public String getNameEn() {        return this.nameEn;    }    public void setNameEn(String nameEn) {        this.nameEn = nameEn;    }}

创建CheckResult类和xml文件

package com.sshdemo.entity;import java.util.Date;/** * 审核结果 实体类。  */public class CheckResult implements java.io.Serializable {    // Fields    private static final long serialVersionUID = 8366759716422180617L;    private long id;    private String sheetType;    private long sheetId;    private Date checkTime;    private String type;    private Employee checker;    private String result;    private String comment;    // Constructors    /** default constructor */    public CheckResult() {    }    /** minimal constructor */    public CheckResult(String sheetType, long sheetId, Date checkTime,            String type, Employee checker, String result) {        this.sheetType = sheetType;        this.sheetId = sheetId;        this.checkTime = checkTime;        this.type = type;        this.checker = checker;        this.result = result;    }    /** full constructor */    public CheckResult(String sheetType, long sheetId, Date checkTime,            String type, Employee checker, String result, String comment) {        this.sheetType = sheetType;        this.sheetId = sheetId;        this.checkTime = checkTime;        this.type = type;        this.checker = checker;        this.result = result;        this.comment = comment;    }    // Property accessors    /**     * @return 编号     */    public long getId() {        return this.id;    }    public void setId(long id) {        this.id = id;    }    /**     * @return 单据类型     */    public String getSheetType() {        return this.sheetType;    }        public void setSheetType(String sheetType) {        this.sheetType = sheetType;    }        /**     * @return 单据编号     */    public long getSheetId() {        return this.sheetId;    }    public void setSheetId(long sheetId) {        this.sheetId = sheetId;    }    /**     * @return 审核时间     */    public Date getCheckTime() {        return this.checkTime;    }    public void setCheckTime(Date checkTime) {        this.checkTime = checkTime;    }    /**     * @return 审核类别     */    public String getType() {        return this.type;    }    public void setType(String type) {        this.type = type;    }        /**     * @return 审核人     */    public Employee getChecker() {        return this.checker;    }    public void setChecker(Employee checker) {        this.checker = checker;    }    /**     * @return 审核结果     */    public String getResult() {        return this.result;    }    public void setResult(String result) {        this.result = result;    }    /**     * @return 审核意见     */    public String getComment() {        return this.comment;    }    public void setComment(String comment) {        this.comment = comment;    }}

创建ClaimVoucher类

package com.sshdemo.entity;import java.util.Date;import java.util.HashSet;import java.util.Set;/** * 报销申请单 实体类。  */public class ClaimVoucher implements java.io.Serializable {    // Fields    private static final long serialVersionUID = -1763618295413371212L;    private long id;    private Employee nextDealBy;    private Employee creator;    private Date createTime;    private String event;    private double totalAccount;    private String status;    private Set
     
       details = new HashSet
      
       (0);    // Constructors        /** default constructor */    public ClaimVoucher() {    }    /** minimal constructor */    public ClaimVoucher(Employee employeeByCreateSn, Date createTime,            String event, double totalAccount, String status) {        this.creator = employeeByCreateSn;        this.createTime = createTime;        this.event = event;        this.totalAccount = totalAccount;        this.status = status;    }    /** full constructor */    public ClaimVoucher(Employee employeeByNextDealSn,            Employee employeeByCreateSn, Date createTime, String event,            double totalAccount, String status, Set
       
         claimVoucherDetails) {        this.nextDealBy = employeeByNextDealSn;        this.creator = employeeByCreateSn;        this.createTime = createTime;        this.event = event;        this.totalAccount = totalAccount;        this.status = status;        this.details = claimVoucherDetails;    }    // Property accessors    /**     * @return 编号     */    public long getId() {        return this.id;    }    public void setId(long id) {        this.id = id;    }        /**     * @return 待处理人     */    public Employee getNextDealBy() {        return this.nextDealBy;    }    public void setNextDealBy(Employee employeeByNextDealSn) {        this.nextDealBy = employeeByNextDealSn;    }        /**     * @return 填报人     */    public Employee getCreator() {        return this.creator;    }        public void setCreator(Employee employeeByCreateSn) {        this.creator = employeeByCreateSn;    }    /**     * @return 填写时间     */    public Date getCreateTime() {        return this.createTime;    }    public void setCreateTime(Date createTime) {        this.createTime = createTime;    }    /**     * @return 事由     */    public String getEvent() {        return this.event;    }    public void setEvent(String event) {        this.event = event;    }    /**     * @return 总金额     */    public double getTotalAccount() {        return this.totalAccount;    }    public void setTotalAccount(double totalAccount) {        this.totalAccount = totalAccount;    }    /**     * @return 状态     */    public String getStatus() {        return this.status;    }    public void setStatus(String status) {        this.status = status;    }    /**     * @return 明细     */    public Set
        
          getDetails() {        return this.details;    }    public void setDetails(Set
         
           claimVoucherDetails) {        this.details = claimVoucherDetails;    }}

创建ClaimVoucherDetail类和xml

package com.sshdemo.entity;/** * 报销申请单明细 实体类。  */public class ClaimVoucherDetail implements java.io.Serializable {    // Fields    private static final long serialVersionUID = -5640087904678377183L;    private long id;    private ClaimVoucher master;    private String item;    private double account;    private String desc;    // Constructors    /** default constructor */    public ClaimVoucherDetail() {    }    /** full constructor */    public ClaimVoucherDetail(ClaimVoucher claimVoucher, String item,            double account, String desc) {        this.master = claimVoucher;        this.item = item;        this.account = account;        this.desc = desc;    }    // Property accessors    /**     * @return 编号     */    public long getId() {        return this.id;    }    public void setId(long id) {        this.id = id;    }    /**     * @return 主单     */    public ClaimVoucher getMaster() {        return this.master;    }    public void setMaster(ClaimVoucher claimVoucher) {        this.master = claimVoucher;    }        /**     * @return 项目     */    public String getItem() {        return this.item;    }    public void setItem(String item) {        this.item = item;    }        /**     * @return 金额     */    public double getAccount() {        return this.account;    }    public void setAccount(double account) {        this.account = account;    }    /**     * @return 费用说明     */    public String getDesc() {        return this.desc;    }    public void setDesc(String desc) {        this.desc = desc;    }}

6.创建com.sshdemo.dao的employeeDao接口

package com.sshdemo.dao;import java.io.Serializable;import java.util.List;import com.sshdemo.entity.Employee;/** * DAO接口。 *  */public interface EmployeeDao {    /**     * 添加用户     *      * @param employee  用户     */    void add(Employee employee);    /**     * 根据用户Id删除对象     * @param id主键     */    void deleteById(Serializable id);    /**     * 修改用户     *      * @param employee用户     */    void update(Employee employee);    /**     * 根据用户id加载对象     * @param id主键     * @return 返回用户对象     */    Employee get(Serializable id);    /**     * 根据查询条件查询用户数据。     * @param condition查询条件     * @return 如果condition为null，返回所有用户数据，否则，使用用户名和密码查询用户数据     */    List
     
       find(Employee condition);}

7.创建对应的实现类

package com.sshdemo.dao.hibimpl;import java.io.Serializable;import java.util.List;import org.springframework.orm.hibernate3.HibernateTemplate;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import org.springframework.transaction.annotation.Transactional;import com.sshdemo.dao.EmployeeDao;import com.sshdemo.entity.Employee;/** * 这个是员工类的dao层,继承HibernateDaoSupport,可以按ctrl+F3 * 可以看到这个类中包含一个getHibernateTemplate()和setHibernateTemplate()方法 * 我们通过上下文配置时就已经将template用spring进行了注入,此时我们就通过 * teaplate可以获取到相应的数据源,使用template进行调用对应的增删改查 *  */public class EmployeeDaoHibImpl extends HibernateDaoSupport implements        EmployeeDao {    /*     * (non-Javadoc)     *      * @see com.sshdemo.dao.EmployeeDao#add(com.sshdemo.entity.Employee)     */    @Transactional    public void add(Employee employee) {        HibernateTemplate hibTemp = getHibernateTemplate();        // hibTemp.setFlushMode(HibernateTemplate.FLUSH_AUTO);        hibTemp.save(employee);    }    /*     * (non-Javadoc)     *      * @see com.sshdemo.dao.EmployeeDao#deleteById(java.io.Serializable)     */    public void deleteById(Serializable id) {        super.getHibernateTemplate().delete(this.get(id));    }    /*     * (non-Javadoc)     *      * @see com.sshdemo.dao.EmployeeDao#update(com.sshdemo.entity.Employee)     */    public void update(Employee employee) {        super.getHibernateTemplate().update(employee);    }    /*     * (non-Javadoc)     *      * @see com.sshdemo.dao.EmployeeDao#get(java.io.Serializable)     */    public Employee get(Serializable id) {        return (Employee) super.getHibernateTemplate().get(Employee.class, id);    }    /*     * (non-Javadoc)     *      * @see com.sshdemo.dao.EmployeeDao#find(com.sshdemo.entity.Employee)     */    @SuppressWarnings("unchecked")    public List
     
       find(Employee condition) {        return getHibernateTemplate().find(                "from Employee e where e.name=? and e.password=?",                new Object[] { condition.getName(), condition.getPassword() });    }}

8.在com.sshdemo.utils下定义一个MD5加密算法的类

package com.sshdemo.utils;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.security.MessageDigest;public class MD5 {    private String inStr;    //输入java.security.MessageDigest下面的一个类    private MessageDigest md5;    /**     * 以下是一个带参数的构造函数,创建对象时就将     * inStr和MessageDigest赋值     * @param 杨超     */    public MD5(String inStr) {        this.inStr = inStr;        try {            this.md5 = MessageDigest.getInstance("MD5");        } catch (Exception e) {            System.out.println(e.toString());            e.printStackTrace();        }    }    /* 下面是关键的md5算法 */    public String compute() {        //将创建对象时的字符串转换成字符数组        char[] charArray = this.inStr.toCharArray();        //根据字符数组的长度初始化一个Byte数组        byte[] byteArray = new byte[charArray.length];        //将字符数组转换成byte数组        for (int i = 0; i < charArray.length; i++)            byteArray[i] = (byte) charArray[i];                //将字节数组通过digest 计算存储在byte数组中        byte[] md5Bytes = this.md5.digest(byteArray);        //用它来保证线程安全        StringBuffer hexValue = new StringBuffer();                for (int i = 0; i < md5Bytes.length; i++) {            //将每个md5Bytes进行一个或的位运算符计算,最终将其转换成二进制数字            int val = ((int) md5Bytes[i]) & 0xff;            if (val < 16)                hexValue.append("0");            hexValue.append(Integer.toHexString(val));        }        //返回一个字符串        return hexValue.toString();    }    /* 下面是主函数调用 */    public static void main(String[] args) {        String A = null;        try {            System.out.println("请输入你要加密的数据:");            BufferedReader br = new BufferedReader(new InputStreamReader(                    System.in));            A = br.readLine();        } catch (IOException e) {        }        ;        MD5 md5 = new MD5(A);        String postString = md5.compute();        System.out.println("加密后的数据:" + postString);    }}

9.创建MVC设计模式的C层

package com.sshdemo.action;import java.util.Map;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;import com.sshdemo.entity.Employee;import com.sshdemo.service.EmployeeService;import com.sshdemo.utils.MD5;/** * 用户登录action。 *  */public class UserAction extends ActionSupport {    private static final long serialVersionUID = -6095372451084071851L;    private Employee employee = null;    private EmployeeService employeeService = null;    /**     * 用户登录。     *      * @return     * @throws Exception     */    public String login() throws Exception {        Employee newEmployee = null;        try {            // 对登录密码进行MD5加密            employee.setPassword(new MD5(employee.getPassword()).compute());            newEmployee = employeeService.login(employee);        } catch (Exception e) {            this.addActionMessage(e.getMessage());        }        String ret = INPUT;        if (newEmployee == null) {            ret = INPUT;        } else {            Map
     
       session = ActionContext.getContext()                    .getSession();            session.put("employee", newEmployee);            String nameCn = newEmployee.getPosition().getNameCn();            if ("普通员工".equals(nameCn)) {                ret = "staff";            } else if ("部门经理".equals(nameCn)) {                ret = "deptManager";            } else if ("总经理".equals(nameCn)) {                ret = "manager";            } else if ("财务".equals(nameCn)) {                ret = "cashier";            }        }        return ret;    }    /**     * 用户退出。     *      * @return     * @throws Exception     */    public String logout() throws Exception {        ActionContext ac = ActionContext.getContext();        ac.getSession().remove("employee");        return SUCCESS;    }    public String register() throws Exception    {        String ret = "registerfail";        try {            // 对登录密码进行MD5加密            employee.setPassword(new MD5(employee.getPassword()).compute());            employeeService.register(employee);            ret = "registerok";        } catch (Exception e) {            this.addActionMessage(e.getMessage());        }        return ret;    }    public void setEmployee(Employee employee) {        this.employee = employee;    }    public void setEmployeeService(EmployeeService employeeService) {        this.employeeService = employeeService;    }    public Employee getEmployee() {        return employee;    }    public EmployeeService getEmployeeService() {        return employeeService;    }}

10.创建一个ExportDb创建在各实体类中定义好的xml对应的数据库表格

package com.sshdemo.utils;import org.hibernate.cfg.Configuration;import org.hibernate.tool.hbm2ddl.SchemaExport;;/** * 将hbm生成ddl * @author BCH * */public class ExportDb {    public static void main(String[] args) {        //默认读取hibernate.cfg.xml文件        Configuration cfr = new Configuration().configure();                SchemaExport export = new SchemaExport(cfr);        export.create(true, true);    }}

11.创建对应的jsp

<%@ page language="java" pageEncoding="UTF-8"%><%@ taglib prefix="s" uri="/struts-tags"%>            登录                            登录

<%@ taglib prefix="s" uri="/struts-tags"%>,这里引入了一个jsp脚本的指令，定义了一个s前缀 注意：这里对应的name=employee.name;这里对应的是实体类中name和password属性 register.jsp

<%@ page language="java" pageEncoding="UTF-8"%><%@ taglib prefix="s" uri="/struts-tags"%>            注册                            注册

manager,jsp

<%@ page language="java" pageEncoding="UTF-8"%>            总经理待审核页            总经理待审核页
        <%            if (request.getSession().getAttribute("employee") != null){        %>                    ${sessionScope.employee.name } 登录成功        
        <%            } else {        %>                    你还没登录，请您先登录。        
        <%            }        %>        
        继续操作

staff.jsp

<%@ page language="java" pageEncoding="UTF-8"%>            添加报销单页面            添加报销单页面
        <%            if (request.getSession().getAttribute("employee") != null){        %>                    ${sessionScope.employee.name } 登录成功        
        <%            } else {        %>                    你还没登录，请您先登录。        
        <%            }        %>        
        继续操作

cashier.jsp

<%@ page language="java" pageEncoding="UTF-8"%>            财务处理页            财务处理页
        <%            if (request.getSession().getAttribute("employee") != null){        %>                    ${sessionScope.employee.name } 登录成功        
        <%            } else {        %>                    你还没登录，请您先登录。        
        <%            }        %>        
        继续操作

deptManager.jsp

<%@ page language="java" pageEncoding="UTF-8"%>            部门经理待审核页            部门经理待审核页
        <%            if (request.getSession().getAttribute("employee") != null){        %>                    ${sessionScope.employee.name } 登录成功        
        <%            } else {        %>                    你还没登录，请您先登录。        
        <%            }        %>        
        继续操作

运行原理以login.jsp为例：

直接在eclipse上运行即可：点击登录后—后将表单提交到action后面对应的login去—此时会去struts.xml文件里面找到name=login的action，然后就会根据class找到对应业务处理的类的位置及其对应的Method方法

—由于在jsp定义了对应的name=employee.XX它就会去找实体类对应的属性，此时它对employee就已经做了一个封装，将前端传回的参数new 成了一个对象，我们拿到对象之后，就可以对它进行一系列的操作

并返回不同的结果—此时结果又会回到struts.xml中的<result name="input">/login.jsp</result>，它会根据不同的结果判断显示出不同的结果

其它注册等原理一样，不再赘述

总结：对应SSH各部分所起到的作用：spring起一个链接的作用，使得代码之间的耦合性降低，如数据源的配置sqlSessionFactory、对应的template的注入等

　　struts取代了servlet,通过jsp上的指令映射到struts配置文件，然后再映射到对应业务逻辑处理所在的位置，根据返回结果，显示出不同的视图

　　Hibernate它起到的作用不用去管JDBC实现，直接对对象进行操作，最终会根据它的HQL语句对数据库实现增删改查
