这就是SSH框架内容很多，随着下面一个案例来进入分析：

### 1 首先项目是依赖maven进行管理的，创建一个动态的web项目 ###

### 2 在pom.xml导入相关jar包，配置如下: ###

### 3 创建简单Student类，一般在开发中javabean放置在entity下，如com.yc.entity;持久层放在dao ，如com.yc.dao，业务层放在service,如com.yc.service ,控制层放置在controller，Student类如下(本案例的增删改查是对Student): ###

package com.yc.entity;
    public class Student {
    	public int id ;
    	public String name;
    	public String pwd;
    	public int getId() {
    		return id;
    	}
    	public void setId(int id) {
    		this.id = id;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getPwd() {
    		return pwd;
    	}
    	public void setPwd(String pwd) {
    		this.pwd = pwd;
    	}
    	@Override
    	public String toString() {
    		return "Student [id=" + id + ", name=" + name + ", pwd=" + pwd + "]";
    	}
    
    }

Student在数据库对应表示student：

create table student(
      id int primary key auto_increment,
      name varchar(20),
      pwd varchar(50) 
    )

## ##

### 4 创建映射文件，一般命名规则是类名.hbm.xml,因此映射文件为Student.hbm.xml: ###

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-mapping PUBLIC
              "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
              "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
    <hibernate-mapping>
      <class name="com.yc.entity.Student"   table="student">
        <id name="id" type="java.lang.Integer">
         <column name="id"/>
         <generator  class="native"/>
        </id>
        <property name="name" type="java.lang.String">
         <column  name="name" />
        </property>
         <property name="pwd" type="java.lang.String">
         <column  name="pwd" />
        </property>
      </class>
    </hibernate-mapping>

### 5  编写dao层接口，StudentDao： ###

package com.yc.dao;
    import com.yc.entity.Student;
    public interface StudentDao {
    	//登录
    	public int login(Student student);
    	//注册
    	public int add(Student student);
    	
    	//修改
    	public int update(Student student);
    	
    	//注销
    	public int del(Student student);
    
    }

### 6 实现Dao层接口，StudentDaoImpl： ###

package com.yc.dao.Impl;
    import java.util.List;
    import javax.annotation.Resource;
    import org.hibernate.HibernateException;
    import org.hibernate.Query;
    import org.hibernate.Session;
    import org.hibernate.SessionFactory;
    import org.hibernate.Transaction;
    import org.springframework.stereotype.Service;
    import com.yc.dao.StudentDao;
    import com.yc.entity.Student;
    @Service
    public class StudentDaoImpl  implements StudentDao {
    	
    	@Resource(name="sessionFactory")
    	public SessionFactory sessionFactory;
      
    	@Override
    	public int login(Student student) {//登录操作
    		
    		Session session=sessionFactory.getCurrentSession();
    		Query query=session.createQuery("from Student where name= ? and pwd= ?");
    		query.setParameter(0,student.getName());//注入参数
    		query.setParameter(1,student.getPwd());
    		List<Student> list=query.list();
    		System.out.println(list);
    		if(list.size()>0&&list.get(0)!=null){
    			return 1;  //返回1为成功
    		}
    		return 0; //返回0为失败
    	}
    
    	@Override
    	public int add(Student student) {  //注册操作
    	   try {
    		Session session=sessionFactory.getCurrentSession();
    		   Query query=session.createSQLQuery("insert  into (name,pwd) student values(?,?)").addEntity(Student.class);
    		   query.setString(0,student.getName());
    		   query.setString(1, student.getPwd());
    		   session.save(student);
    		   return 1;
    	} catch (HibernateException e) {
    		// TODO Auto-generated catch block
    		e.printStackTrace();
    		return 0;
    	}
    	}
    
    	@Override
    	public int update(Student student) {   //修改操作
    		 try {
    				Session session=sessionFactory.getCurrentSession();
    				Transaction  transAction=session.beginTransaction();
    				   Query query=session.createSQLQuery("update student set pwd=? where name=? ").addEntity(Student.class);
    				   query.setString(0,student.getPwd());
    				   query.setString(1, student.getName());
    				   query.executeUpdate();
    				   transAction.commit();
    				   return 1;
    			} catch (HibernateException e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    				return 0;
    			}
    	}
    
    	@Override
    	public int del(Student student) {  //注销用户
    		 try {
    				Session session=sessionFactory.getCurrentSession();
    				Transaction  transAction=session.beginTransaction();
    				   Query query=session.createSQLQuery("delete from student where name=?").addEntity(Student.class);
    				   query.setString(0,student.getName());
    				   query.executeUpdate();
    				   transAction.commit();
    				   return 1;
    			} catch (HibernateException e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    				return 0;
    			}
    	}
    
    }

### 7 编写业务层借口，StudentService： ###

package com.yc.service;
    import com.yc.entity.Student;
    public interface StudentService {
    	//登录
    		public int login(Student student);
    		//注册
    		public int add(Student student);		
    		//修改
    		public int update(Student student);
    		//注销
    		public int del(Student student);
    }

### 8 实现业务层接口，StudentServiceImpl： ###

package com.yc.service.Impl;
    import javax.annotation.Resource;
    import org.springframework.stereotype.Service;
    import com.yc.dao.StudentDao;
    import com.yc.entity.Student;
    import com.yc.service.StudentService;
    
    @Service
    public class StudentServiceImpl implements StudentService {
        
    	@Resource(name="studentDaoImpl")
    	public StudentDao studentDao;
    	
    	@Override
    	public int login(Student student) {
    		return studentDao.login(student);
    	}
    
    	@Override
    	public int add(Student student) {
    		return studentDao.add(student);
    	}
    
    	@Override
    	public int update(Student student) {
    		return studentDao.update(student);
    	}
    
    	@Override
    	public int del(Student student) {
    		return studentDao.del(student);
    	}
    
    }

### 9 编写action类，用于客户端请求处理：本案例实现对Student对象的增删改查，所以编写了四个Action类：LoginAction、AddAction、UpdateAction、DelAction分别实现登录、注册、修改用户密码、注销用户操作： ###

LoginAction控制类：

package com.yc.controller;
    import javax.annotation.Resource;
    import org.springframework.stereotype.Controller;
    import com.opensymphony.xwork2.ActionContext;
    import com.opensymphony.xwork2.ActionSupport;
    import com.yc.entity.Student;
    import com.yc.service.StudentService;
    
    @Controller
    public class LoginAction extends ActionSupport{
    	
    	private static final long serialVersionUID = 3867837111230648465L;
    	private String name;
    	private String pwd;
    	private Student student;
    
    	@Resource(name="studentServiceImpl")
    	private StudentService studentService;
    	public Student getStudent() {
    		return student;
    	}
    	public void setStudent(Student student) {
    		this.student = student;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getPwd() {
    		return pwd;
    	}
    	public void setPwd(String pwd) {
    		this.pwd = pwd;
    	}
    	
    	public String login(){
    		Student student=new Student();
    		student.setName(name);
    		student.setPwd(pwd);
    		int result= studentService.login(student);
    		if(result==1){
    			ActionContext text=ActionContext.getContext();
    			text.getSession().put("user",student.getName());
    			return "success";
    		}else{
    			return "error";
    		}
    	}
    
    }

AddAction控制类：

package com.yc.controller;
    import javax.annotation.Resource;
    import org.springframework.stereotype.Controller;
    import com.opensymphony.xwork2.ActionSupport;
    import com.yc.entity.Student;
    import com.yc.service.StudentService;
    
    @Controller
    public class AddAction extends ActionSupport {
    	private static final long serialVersionUID = 5805525553867263305L;
    	private Student student;
    	private String name;
    	private String pwd;
    
    	@Resource(name="studentServiceImpl")
    	private StudentService studentService;
    	
    	public Student getStudent() {
    		return student;
    	}
    	public void setStudent(Student student) {
    		this.student = student;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getPwd() {
    		return pwd;
    	}
    	public void setPwd(String pwd) {
    		this.pwd = pwd;
    	}
    	
    	public String add(){
    		Student student=new Student();
    		student.setName(name);
    		student.setPwd(pwd);
    		int result=studentService.add(student);
    		if(result==1){
    			return "success";
    		}else{
    			return "error";
    		}
    	}
    }

UpdateAction控制类:

package com.yc.controller;
    import javax.annotation.Resource;
    import com.opensymphony.xwork2.ActionSupport;
    import com.yc.entity.Student;
    import com.yc.service.StudentService;
    public class UpdateAction extends ActionSupport {
    
    	private static final long serialVersionUID = 5758012919993220108L;
    	private String name;
    	private String pwd;
    	private Student student;
    
    	@Resource(name="studentServiceImpl")
    	private StudentService studentService;
    	
    	public Student getStudent() {
    		return student;
    	}
    	public void setStudent(Student student) {
    		this.student = student;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getPwd() {
    		return pwd;
    	}
    	public void setPwd(String pwd) {
    		this.pwd = pwd;
    	}
    	
    	public String update(){
    		Student student=new Student();
    		student.setName(name);
    		student.setPwd(pwd);
    		int result= studentService.update(student);
    		if(result==1){
    			return "success";
    		}else{
    			return "error";
    		}
    	}
    }

DelAction控制类:

package com.yc.controller;
    import javax.annotation.Resource;
    import com.opensymphony.xwork2.ActionSupport;
    import com.yc.entity.Student;
    import com.yc.service.StudentService;
    public class DelAction extends ActionSupport {
    	
    	private static final long serialVersionUID = -3188134023173913520L;
    	private String name;
    	private String pwd;
    	private Student student;
    
    	@Resource(name="studentServiceImpl")
    	private StudentService studentService;
    	
    	public Student getStudent() {
    		return student;
    	}
    	public void setStudent(Student student) {
    		this.student = student;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getPwd() {
    		return pwd;
    	}
    	public void setPwd(String pwd) {
    		this.pwd = pwd;
    	}
    	public String del(){
    		Student student=new Student();
    		student.setName(name);
    		student.setPwd(pwd);
    		int result= studentService.del(student);
    		if(result==1){
    			return "success";
    		}else{
    			return "error";
    		}
    	}
    
    }

### 10 接下来就是编写struts的配置文件，将请求交个相应的控制类，struts.xml配置文件如下： ###

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
    
    <struts>
      <constant   name="struts.devMode" value="true">
      </constant>
       <package  name="student"  extends="struts-default" namespace="/">
    
         <action name="login" class="com.yc.controller.LoginAction"  method="login">
           <result   name="success">/success.jsp</result>
           <result   name="error">/error.jsp</result>
         </action>
         
         <action name="add" class="com.yc.controller.AddAction"  method="add">
                 <result   name="success">/index.jsp</result>
                 <result   name="error">/register.jsp</result>
          
         </action>
         
         <action name="update" class="com.yc.controller.UpdateAction"  method="update">
                <result   name="success">/index.jsp</result>
         
         </action>
         
         <action name="del" class="com.yc.controller.DelAction"  method="del">
                  <result   name="success">/index.jsp</result>
           
         </action>
       </package>
    </struts>

### 11 配置web.xml文件: ###

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns="http://java.sun.com/xml/ns/javaee"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    	version="3.0">
      <display-name>Archetype Created Web Application</display-name>
      
      <welcome-file-list>
        	<welcome-file>index.jsp</welcome-file>
        </welcome-file-list>
    	
    	<listener>
    		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    	</listener>
    	<context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>classpath:applicationContext.xml</param-value>
    	</context-param>
    	
    	
    	
    	<filter>
    		<filter-name>OpenSessionView</filter-name>
    		<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
    		<init-param>
    			<param-name>flushMode</param-name>

    		</init-param>
    	</filter>
    	<filter-mapping>
    		<filter-name>OpenSessionView</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>
    	
    	
    	
    	<filter>
    		<filter-name>Struts2</filter-name>
    		<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

    		<filter-name>Struts2</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>
    </web-app>

### 12 配置applicationContext.xml文件: ###
