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 -->
4000
;

<!-- 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





（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=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;

@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";
}

}
