如何整合Struts2 Hibernate 和Spring 首先你必须了解三个框架是如何独立运行的:
代码下载:http://download.csdn.net/detail/zhanglinlang/9775160
Struts2 是通过在web.xml 中 Filter拦截器来启动自己的核心类StrutsPrepareAndExecuteFilter,完成事件的分发。
Spring 是通过 在web.xml 注册监听器来监听ContextLoaderListener,监听web应用的启动事件来完成自己的框架启动工作。
Hibernate 是通过创建SessionFactory工厂手动加载配置文件来完成启动工作,Hibernate是可以通过代码创建SessionFactory,就可以交给Spring通过ioc来控制该类的实例化。
下面就是整合代码:目录结构如下
首先在resource目录下创建 config目录方便管理:
首先配置
Hibernate :
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="foo"> <!-- 配置 打印sql语句到控制台 可选 --> <property name="hibernate.show_sql">true</property> <property name="hibernate.format_sql">true</property> <!-- (重要配置)Hibernate自动建表 配置 create:先删除,再创建 update:如果表不存在就创建,不一样就更新,一样就什么都不做。 create-drop:初始化时创建表,SessionFactory执行close()时删除表。 validate:验证表结构是否一致,如果不一致,就抛异常。 --> <property name="hbm2ddl.auto">update</property> <!-- 设置默认的事务隔离级别: 隔离级别 对应的整数表示 READ UNCOMMITED 1 READ COMMITED 2 REPEATABLE READ 4 SERIALIZEABLE 8 --> <property name="connection.isolation">4</property> <!-- 使用二级缓存,默认是未打开的。 --> <!-- 指定要使用的缓存的提供商,这也就打开了二级缓存 <property name="cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property> <property name="cache.provider_class">org.hibernate.cache.EhCacheProvider</property> --> <!-- 开启使用查询缓存 <property name="cache.use_query_cache">true</property> --> <!-- 指定要使用二级缓存的实体类 <class-cache usage="read-write" class="cn.itcast.l_second_cache.Employee"/> <class-cache usage="read-write" class="cn.itcast.l_second_cache.Department"/> <collection-cache usage="read-write" collection="cn.itcast.l_second_cache.Department.employees"/> --> <!-- 导入映射文件 --> <mapping resource="com/zll/entity/User.hbm.xml"/> <mapping resource="com/zll/entity/Student.hbm.xml"/> </session-factory> </hibernate-configuration>
Struts.xml
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="foo"> <!-- 配置 打印sql语句到控制台 可选 --> <property name="hibernate.show_sql">true</property> <property name="hibernate.format_sql">true</property> <!-- (重要配置)Hibernate自动建表 配置 create:先删除,再创建 update:如果表不存在就创建,不一样就更新,一样就什么都不做。 create-drop:初始化时创建表,SessionFactory执行close()时删除表。 validate:验证表结构是否一致,如果不一致,就抛异常。 --> <property name="hbm2ddl.auto">update</property> <!-- 设置默认的事务隔离级别: 隔离级别 对应的整数表示 READ UNCOMMITED 1 READ COMMITED 2 REPEATABLE READ 4 SERIALIZEABLE 8 --> <property name="connection.isolation">4</property> <!-- 使用二级缓存,默认是未打开的。 --> <!-- 指定要使用的缓存的提供商,这也就打开了二级缓存 <property name="cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property> <property name="cache.provider_class">org.hibernate.cache.EhCacheProvider</property> --> <!-- 开启使用查询缓存 <property name="cache.use_query_cache">true</property> --> <!-- 指定要使用二级缓存的实体类 <class-cache usage="read-write" class="cn.itcast.l_second_cache.Employee"/> <class-cache usage="read-write" class="cn.itcast.l_second_cache.Department"/> <collection-cache usage="read-write" collection="cn.itcast.l_second_cache.Department.employees"/> --> <!-- 导入映射文件 --> <mapping resource="com/zll/entity/User.hbm.xml"/> <mapping resource="com/zll/entity/Student.hbm.xml"/> </session-factory> </hibernate-configuration>
Struts.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="person" namespace="/" extends="struts-default"> <!-- (测试使用)action的创建交给Spring来管理,这里的class 只需要填写spring里对应action对象的bean的id --> <action name="userAction" class="userAction" /> </package> </struts>
Spring.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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <!-- (重要步骤)c3p0连接池配置 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"></property> <property name="jdbcUrl" value="jdbc:mysql:///hibernate?characterEncoding=utf-8"></property> <property name="user" value="root"></property> <property name="password" value="root"></property> </bean> <!-- (重要步骤)spring整合Hibernate配置,这里将Hibernate创建sessionFactory的方法交给Spring管理。 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="configLocations" value="classpath:config/hibernate.cfg.xml"></property> </bean> <!-- (重要步骤)配置Hibernate 事务 如果不开启,数据库是 read_only状态 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 开启事务注解 --> <tx:annotation-driven transaction-manager="transactionManager"/> <!-- 配置Hibernate 的jdbc模板 --> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 测试代码,通过导入文件方式,可以将多个模块分开配置 --> <import resource="classpath:config/testTemple.xml"/> </beans>
testTemple.xml(这个不重要,看看如何配置就行)
<?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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <!-- 配置测试用的实体类 --> <bean id="userAction" class="com.zll.action.UserAction" scope="prototype"> <property name="userService" ref="userService"></property> </bean> <bean id="userService" class="com.zll.service.UserService"> <property name="userDao" ref="userDaoImp"></property> </bean> <bean id="userDaoImp" class="com.zll.dao.UserDaoImp"> <property name="hibernateTemplate" ref="hibernateTemplate"></property> </bean> </beans>
最重要的:
web.xml
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <!-- Spring ContextLoaderListener 配置文件的设置,如果不配置 默认读取 WEB-INF下的applicationContext.xml --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:config/spring.xml</param-value> </context-param> <!-- (重要配置) 注册struts的 StrutsPrepareAndExecuteFilter 类,拦截访问,并根据访问路径进行分发 --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> <init-param> <param-name>config</param-name> <param-value>struts-default.xml,struts-plugin.xml,config/struts.xml</param-value> </init-param> </filter> <!-- 拦截/* 的所有访问,都会交给 --> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- (重要配置)Spring 启动代码,注册监听器,监听servlet启动, --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>

整合细节知识点(了解):
Struts2 和 Spring整合:就是将action的创建交由Spring管理。配置文件中class只需要配置Spring中bean的id就可以。
<action name="userAction" class="SpringBeanId" />
Hibernate和Spring整合:
1、创建连接池的对象交由spring管理
2、Spring提供了SessionFactory的封装类LocalSessionFactory,配置该类,并将数据源配置给它。
3、配置Spring的HibernateTemplate,将SessionFactory配置给他。替代session完成数据操作。
4、spring 事务管理配置,替代Hibernate事务管理
