spring,springMvc和hibernate整合
一：配置web.xml
<?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_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>hibernate-Spring</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.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> /WEB-INF/classes/applicationContext.xml </param-value> </context-param> <servlet> <servlet-name>mySpring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/classes/mySpring-servlet.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mySpring</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!-- hibernate4.0必须 --> <filter> <filter-name>hibernateFilter</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> <init-param> <param-name>sessionFactoryBeanName</param-name> <param-value>sessionFactory</param-value> </init-param> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>flushMode</param-name> <param-value>AUTO</param-value> </init-param> </filter> <filter-mapping> <filter-name>hibernateFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 编码过滤 --> <filter> <filter-name>encodingFilter</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping></web-app>
二：在WEB-INF下创建classes文件，里面放置配置文件，包括：
2.1：applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" 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/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> <!--启用自动扫描 --> <context:component-scan base-package="com.wode"> <context:exclude-filter type="regex" expression=".(dao|service.impl)" /> </context:component-scan> <aop:aspectj-autoproxy /> <!-- 配置C3P0数据源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="com.mysql.jdbc.Driver" /> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/j116?characterEncoding=utf-8" /> <property name="user" value="root" /> <property name="password" value="admin" /> <property name="minPoolSize" value="1" /> <property name="maxPoolSize" value="20" /> <property name="maxIdleTime" value="60" /> <property name="initialPoolSize" value="1" /> <!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 --> <property name="acquireIncrement" value="5" /> <property name="automaticTestTable" value="c3p0TestTable" /> <!--每60秒检查所有连接池中的空闲连接。Default: 0 --> <property name="idleConnectionTestPeriod" value="60" /> <property name="checkoutTimeout" value="3000" /> </bean> <!-- 配置SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <!-- 向SessionFactory中注入数据源 --> <property name="dataSource" ref="dataSource" /> <property name="hibernateProperties"> <props> <!-- 定义Hibernate的方言 --> <prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </prop> <!-- 是否根据需要每次自动更新数据库 <prop key="hibernate.hbm2ddl.auto">update</prop> --> <!-- 控制台显示SQL --> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <!-- 使用SQL注释 --> <prop key="hibernate.use_sql_comments">true</prop> </props> </property> <!-- 浏览entitys包下的所有使用Hibernate注解的JavaBean --> <property name="packagesToScan"> <list> <value>com.wode.bean</value> </list> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 事物配置的模板-偷的 --> <!-- 定义个通知，指定事务管理器 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="delete*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" /> <tx:method name="save*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" /> <tx:method name="update*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" /> <tx:method name="load*" propagation="SUPPORTS" read-only="true" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="userPointCut" expression="execution(* com.wode.service.*.*(..))" /> <aop:aspect id="logAspect" ref="userLogger"> <aop:before method="testLogger" pointcut-ref="userPointCut"></aop:before> </aop:aspect> </aop:config> </beans>
2.2：mySpring-servlet.xml
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd"> <mvc:annotation-driven /> <context:component-scan base-package="com.wode.controller" /> <!-- ViewResolver视图解析器 用于将返回的ModelAndView对象进行分离 --> <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property> <property name="prefix" value="/"></property> <property name="suffix" value=".jsp"></property> </bean></beans>
3：导入核心jar包，放入WEB-INF/lib里面：
4：在src中创建项目，项目结构如下：（根据自己情况命名，尽量按照三层架构的方式创建）
5：创建数据库（省略。。。注意数据库中变量的名字与bean中的Column对应）
6：创建UserBean:
package com.wode.bean;import java.io.Serializable;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.Table;@Entity@Table(name="users")public class User implements Serializable{ @Id @GeneratedValue(strategy=GenerationType.IDENTITY) @Column(name="user_id") private int userId; @Column(name="user_name") private String userName; @Column(name="user_pwd") private String userPwd; @Column(name="user_type") private int userType; public int getUserId() { return userId; } public void setUserId(int userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserPwd() { return userPwd; } public void setUserPwd(String userPwd) { this.userPwd = userPwd; } public int getUserType() { return userType; } public void setUserType(int userType) { this.userType = userType; }}
7：创建dao层和service层的接口：
8：创建dao层的实现类：
package com.wode.dao.impl;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.stereotype.Repository;import com.wode.bean.User;import com.wode.dao.UserDao;@Repositorypublic class UserDaoImpl implements UserDao{ @Autowired @Qualifier("sessionFactory") //等价于@Resource private SessionFactory sessionFactory; public void addUser(User user){ Session session=sessionFactory.getCurrentSession(); session.save(user); }}
9：创建service层的实现类：
package com.wode.service.impl;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.wode.bean.User;import com.wode.dao.UserDao;import com.wode.service.UserService;@Servicepublic class UserServiceImpl implements UserService{ @Resource(name="userDaoImpl") private UserDao userDao; //在接口定义常量 public void login(String name,String pwd){ System.out.println("数据库查询了"+name+" "+pwd); } public void addUser(User user){ System.out.println(user.getUserName()+" "+user.getUserPwd()); user.setUserType(1); userDao.addUser(user); }}
10:创建Controller层对象
package com.wode.controller;import javax.annotation.Resource;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.wode.bean.User;import com.wode.service.UserService;@Controllerpublic class UserController { @Resource(name="userServiceImpl") private UserService service; @RequestMapping("regist.do") public String login(User user){ service.addUser(user); return "success"; }}
11：创建Aop切面，记录日志:
package com.wode.log;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.annotation.AfterThrowing;import org.aspectj.lang.annotation.Around;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.springframework.stereotype.Component;@Component("userLogger")public class UserLogger { public int testLogger(JoinPoint jpt) throws Throwable{ System.out.println("前置记录日志"); return 1; }}
12：如果需要JUnit测试，则需要注意：
package com.wode.dao;import static org.junit.Assert.*;import javax.annotation.Resource;import org.junit.After;import org.junit.Before;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.transaction.annotation.Transactional;import com.wode.bean.User;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations="../../../applicationContext.xml")//这里路径和文件根据自己情况适当修改@Transactional //这里是关键点public class TestUserDao { @Resource(name="userDaoImpl") private UserDao userDao; @Test public void addUserTest() { User user=new User(); user.setUserName("hehe"); user.setUserPwd("admin"); userDao.addUser(user); }}
