spring4mvc+hibernate4整合

1.首先先搭建springMvc

（1）所需jar包：
spring自带: （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;@Componentpublic 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;@Componentpublic 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

（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;@Entitypublic class Student {    private int id;    private String name;    private int age;    @SequenceGenerator(name="sequenceGenerator",sequenceName="student_sequence",allocationSize=1)    @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;@Componentpublic 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;@Componentpublic 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";    }}
