# 整合SSH #

## 1、pom文件中锁定版本 ##

## 2、搭建struts2环境 ##

*  创建struts.xml
 *  web.xml中配置核心过滤器

<filter>
    		<filter-name>struts2</filter-name>
    		<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    	</filter>
    	<filter-mapping>
    		<filter-name>struts2</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>

注意struts版本在2.5之上的，过滤器是org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter，2.1.3版本后是org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter。

## 3、搭建spring环境 ##

*  创建配置文件applicationContext.xml
 *  web.xml中配置监听器

<listener>
    		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    	</listener>
    	
    	<context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>classpath:applicationContext.xml</param-value>
    	</context-param>

## 4、搭建Hibernate环境 ##

*  配置hibernate.cfg.xml

<hibernate-configuration>
    	<session-factory>
    		<property name="show_sql">true</property>
    		<property name="format_sql">true</property>
    		
    		<property name="hbm2ddl.auto">update</property>
    		<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    
    		
    		<mapping resource="xxx.hbm.xml" />
    
    	</session-factory>
    </hibernate-configuration>

## 5、整合struts2和spring ##

关键点：action对象的创建，交给spring；

*  创建action类
 *  将action对象配置到spring配置文件中；
 *  struts.xml配置文件中，action标签的class属性值配置为spring工厂中action的id；

## 6、整合spring和hibernate ##

*  配置数据源datasource；

<context:property-placeholder location="classpath:db.properties" ></context:property-placeholder>
    
    	
    	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    		<property name="driverClassName" value="${jdbc.driverClassName}" />
    		<property name="url" value="${jdbc.url}"></property>
    		<property name="username" value="${jdbc.username}"></property>
    		<property name="password" value="${jdbc.password}"></property>
    	</bean>

*  配置sessionFactory

<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    		<property name="dataSource">
    			<ref bean="dataSource" />
    		</property>
    		
    		<property name="configLocations" value="classpath:hibernate.cfg.xml"></property>
    	</bean>

*  配置事务管理：（顶级接口PlatFormTransactionManager）

1.  JDBC: DataSourceTransactionManager
2.  Hibernate: HibernateTransactionManager

<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    		<property name="sessionFactory" ref="sessionFactory" />
    	</bean>

*  事务管理

<tx:advice id="txAdvice" transaction-manager="transactionManager">
    		<tx:attributes>
    			
    			<tx:method name="*" propagation="REQUIRED" />
    		</tx:attributes>
    	</tx:advice>
    	<aop:config>
    		
    		<aop:pointcut id="cut" expression="execution(* cn.com.plagh.service.*.*(..))" />
    		
    		<aop:advisor advice-ref="txAdvice" pointcut-ref="cut" />
    	</aop:config>
    
    	
    	
    	<tx:annotation-driven transaction-manager="transactionManager" />
