spring4mvc+hibernate4整合

1.首先先搭建springMvc

（1）所需jar包：
spring自带: 这里写图片描述（不了解，所以把spring4的所有jar包都加进来）
spring还需要：

以上jar包包括了spring4mvc_hibernate4中spring所有需要的包。

（2）在web.xml中加入springmvc的控制，springbeans的控制，以及中文乱码的控制

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <display-name></display-name>   
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

   <!--控制springbeans-->
   <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:/beans.xml</param-value>
   </context-param>
   <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   </listener>

    <!-- 解决中文乱码 （只对post提交有效） -->
    <filter>    
        <filter-name>Character Encoding</filter-name>    
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>    
        <init-param>    
            <param-name>encoding</param-name>    
            <param-value>UTF-8</param-value>    
        </init-param>    
    </filter>    
    <filter-mapping>    
        <filter-name>Character Encoding</filter-name>    
        <url-pattern>/*</url-pattern>    
    </filter-mapping>  

    <!--springmvc必须-->
    <servlet>  
        <servlet-name>springmvc</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <init-param>  
            <param-name>contextConfigLocation</param-name>  
            <param-value>/WEB-INF/springmvc-context.xml</param-value>  
        </init-param>  
    </servlet>  

    <servlet-mapping>  
        <servlet-name>springmvc</servlet-name>  
        <url-pattern>*.do</url-pattern>  
    </servlet-mapping> 

</web-app>

（3）在web.xml中DispatcherServlet所写的对应位置上创建springmvc-context.xml，在listener所写的位置即src目录下下创建beans.xml

springmvc-context.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        ">

    <!-- springmvc 注解驱动 -->
    <mvc:annotation-driven/>
    <!-- 扫描器 -->
    <context:component-scan base-package="com.controller"/><!-- 重中之重  base-package一定要写到controller一层, 否则不好使 整合hibernate用getCurrentSession()会报 No Session found for current thread -->


    <!-- 配置视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/view/"></property>
        <!-- 后缀 -->
        <property name="suffix" value=".jsp"></property>
    </bean>

</beans>

beans.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        ">

    <context:annotation-config />
    <context:component-scan base-package="com.dao,com.service,com.controller" />
</beans>

（4）创建WebRoot/index.jsp、WebRoot/view/student/add.jsp、WebRoot/view/student/list.jsp
内容分别为

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    <title>导航页</title>
  </head>

  <body>
        <a href="student/add.do">新增</a> <br/>
  </body>
</html>

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    <title>新增用户页</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

  </head>

  <body>
        <form action="student/add.do" method="post">
            姓名:<input type="text" name="name"/><br/>
            年龄:<input type="text" name="age"/><br/>
            <input type="submit" value="提交"/>
        </form>
        ${result}
  </body>
</html>

（5）在src下加入dao类com.dao.StudentDao.java，service类com.service.StudentService.java，控制类com.controller.StudentController.java

package com.dao;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;

@Component
public class StudentDao {

    public void save(){
        System.out.println("插入");
    }
}

package com.service;

import javax.annotation.Resource;
import org.springframework.stereotype.Component;
import com.dao.StudentDao;

@Component
public class StudentService {
    private StudentDao studentDao;

    public StudentDao getStudentDao() {
        return studentDao;
    }
    @Resource
    public void setStudentDao(StudentDao studentDao) {
        this.studentDao = studentDao;
    }

    public void addStudent(){
        studentDao.save();
    }
}

package com.controller;

import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.service.StudentService;

@Controller
@RequestMapping("/student")
public class StudentController {

    private StudentService studentService;

    public StudentService getStudentService() {
        return studentService;
    }
    @Resource
    public void setStudentService(StudentService studentService) {
        this.studentService = studentService;
    }

    @RequestMapping("/add.do")
    public String addStudent(String name,String age,Model model){

        System.out.println(name+"-"+age);
        String result = (name==null||"".equals(name))?"":name+"新增成功";
        model.addAttribute("result",result);

        if(name!=null && age!=null){
            studentService.addStudent();
        }

        return "student/add";
    }

}

（6）访问http://127.0.0.1:8080/spring4mvc_hibernate4测试springmvc是否成功。
至此的源码：http://download.csdn.net/detail/qwcs163/9142475

（7） spring配置正确，接下来整合hibernate，首先导入hibernate4 jar包

这里写图片描述

（8）创建model层

package com.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;

@Entity
public class Student {
    private int id;
    private String name;
    private int age;
    @SequenceGenerator(name="sequenceGenerator",sequenceName="student_sequence",allocationSize=)
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="sequenceGenerator")
    @Id
    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 int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }

}

（9）修改beans.xml，加入hibernate整合以及事物

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
        ">

    <context:annotation-config />
    <context:component-scan base-package="com.dao,com.service,com.controller" />


    <bean id="myDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
        <property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:orcl"/>
        <property name="username" value="cat"/>
        <property name="password" value="cat"/>
    </bean>


    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="myDataSource" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>  
                <prop key="hibernate.show_sql">true</prop>  
                <prop key="hibernate.format_sql">true</prop>  
                <prop key="hibernate.hbm2ddl.auto">update</prop>  
                <prop key="hibernate.max_fetch_depth">1</prop>  
                <prop key="hibernate.use_sql_comments">true</prop>
            </props>
        </property>
        <property name="packagesToScan">
            <list>
                <value>com.model</value>
            </list>
        </property>
    </bean>

    <!-- 配置Hibernate事务管理器 -->
    <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
      <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="get*" read-only="true" />
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>

    <aop:config proxy-target-class="true">
        <aop:pointcut id="serviceOperation" expression="execution(public * com.service.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation"/>
    </aop:config>

</beans>

（10）修改dao层，service层，修改controller层。

package com.dao;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Component;

import com.model.Student;

@Component
public class StudentDao {
    private SessionFactory sessionFactory;
    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    @Resource
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    public void save(Student s){
        Session session = sessionFactory.getCurrentSession();
        session.save(s);
        System.out.println("插入");
    }
}

package com.service;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;

import com.dao.StudentDao;
import com.model.Student;

@Component
public class StudentService {
    private StudentDao studentDao;

    public StudentDao getStudentDao() {
        return studentDao;
    }
    @Resource
    public void setStudentDao(StudentDao studentDao) {
        this.studentDao = studentDao;
    }

    public void addStudent(Student s){
        studentDao.save(s);
    }
}

package com.controller;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.model.Student;
import com.service.StudentService;

@Controller
@RequestMapping("/student")
public class StudentController {

    private StudentService studentService;

    public StudentService getStudentService() {
        return studentService;
    }
    @Resource
    public void setStudentService(StudentService studentService) {
        this.studentService = studentService;
    }

    @RequestMapping("/add.do")
    public String addStudent(String name,String age,Model model){

        System.out.println(name+"-"+age);
        String result = (name==null||"".equals(name))?"":name+"新增成功";
        model.addAttribute("result",result);

        if(name!=null && age!=null){
            Student s= new Student();
            s.setName(name);
            s.setAge(Integer.parseInt(age));
            studentService.addStudent(s);
        }

        return "student/add";
    }

}

（11）结构图及源码
