【Spring】Spring+Struts2+Hibernate3整合（十七）

即：

Spring与Struts整合

Spring与Hibernate整合

 

需求：

JSP页面显示员工信息  （查询）

 

 

整合步骤：

1） 引入SSH Jar文件

Struts 核心jar

Hibernate 核心jar

Spring

Core  核心功能

Web  对web模块支持

Aop   aop支持

Orm   对hibernate支持

Jdbc/tx  jdbc支持包、事务相关包

 

2）配置

Web.xml

初始化struts功能、spring容器

Struts.xml   配置请求路径与映射action的关系

Spring.xml  IOC容器配置

bean-base.xml     【公用信息】

bean-service.xml

bean-dao.xml

bean-action.xml

 

3）开发

Entity/Dao/service/action

Bean-base.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: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.xsd      http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context.xsd         http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop.xsd         http://www.springframework.org/schema/tx      http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 所有配置的公共部门 --><!-- 1) 连接池实例 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="com.mysql.jdbc.Driver"></property><property name="jdbcUrl" value="jdbc:mysql:///hib_demo"></property><property name="user" value="root"></property><property name="password" value="root"></property><property name="initialPoolSize" value="3"></property><property name="maxPoolSize" value="6"></property></bean> <!-- 2) SessionFactory实例创建 --><!-- 所有的配置都由spring维护(项目中不需要hibernate.cfg.xml啦) --><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><!-- a. 连接池 --><property name="dataSource" ref="dataSource"></property><!-- b. hibernate常用配置： 方言、显示sql、自动建表等 --><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.hbm2ddl.auto">update</prop></props></property><!-- c. 映射配置 --><property name="mappingLocations"><list><value>classpath:cn/itcast/entity/*.hbm.xml</value></list></property></bean><!-- 3) 事务配置 --><!-- # 事务管理器 --><bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property></bean><!-- # 事务增强 --><tx:advice id="txAdvice" transaction-manager="txManager"><tx:attributes><tx:method name="*" read-only="false"/></tx:attributes></tx:advice><!-- # AOP配置 --><aop:config><aop:pointcut expression="execution(* cn.itcast.service.*.*(..))" id="pt"/><aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/></aop:config></beans>     

 

 

Struts.xml(与Spring整合的时候，aciton的class应该写springbean的名称)

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN""http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <package name="emp" extends="struts-default"> <!-- action实例交给spring容器创建 --><action name="show" class="employeeAction" method="execute"><result name="success">/index.jsp</result></action> </package> </struts>
