ssh框架整合
一.思路
1.导包
struts2: appsstruts2-blankWEB-INFlib所有包
struts2-spring-plugin-2.3.28.jar
hibernate: lib
equired所有包
libjpahibernate-jpa-2.0-api-1.0.0.Final(持久化规范,接口)
hibernate3.jar
slf4j-api.jar
slf4j-log4j12.jar
spring: 4+2个:libs目录 beans|context|core|expression|
commons-logging|log4j
aop包4个：libs目录 spring-aop|spring-aspect
aopalliance(联盟包)|aspectj.weaver.jar(织入包)
jdbc+事务:spring-jdbc|spring-tx|spring-orm|c3p0
web包:spring-web
数据库驱动包： mysql-connector-java.jar
注：总共目前先用的包是38个包
2.创建配置文件
struts
hibernate
spring
3.整合hibernate
三个重要的对象
1)HibernateTemplate ，操作我们po类（可以配置bean也可以继承HibernateDaoSupport）
2)LocalSessionFactoryBean:创建sessionFactory
3)HibernateTransactionManager:hibernate管理事务
李老师讲了两种方法，第一种是不用c3po数据源，另外一种使用c3p0数据源。
二 整合（c3p0数据源）
2.0配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>myssh_2</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- spring的监听 用于启动applicationContext.xml -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext2.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- struts2过滤器要放在最下面 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
2.1 配置struts.xml
<?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>
<constant name="struts.devMode" value="true"></constant>
<!-- 把Action实列交由spring来管理,这个常量必须配置 -->
<constant name="struts.objectFactory" value="spring"></constant>
<package name="" namespace="/" extends="struts-default">
<!-- 把Action创建交于spring容器去创建，class：名字对应的是applicationContext.中，要配置的 Action的bean的名字 -->
<action name="userAction_*" class="userAction" method="{1}">
<result name="success" type="redirect">/success.jsp</result>
</action>
</package>
</struts>
2.2 hibernate.cfg.xml和User.hbm.xml
说明：此时我们是用Spring去整合hibernate,这里不用配置
配置User.hbm.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.icss.pojo">
<class name="User" table="user">
<id name="uid">
<generator class="native"></generator>
</id>
<property name="name"></property>
<property name="pwd"></property>
</class>
</hibernate-mapping>
2.3 applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans"

<!-- 是要引用外部properties文件来使用 c3p0连接池 -->
<!-- 0.1读取properties文件 -->
<context:property-placeholder location="classpath:db.properties"/>
<!-- 0.2配置c3po -->
<bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<!-- 1.整合hibernate-->
创建sessionFactory
<bean name="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<!-- 连接数据源 -->
<property name="dataSource" ref="dataSource"></property>
<!-- spring 代替 hibernate.cfg.xml文件 -->
<property name="hibernateProperties">

<!-- <prop key="hibernate.current_session_context_class">thread</prop> -->

</property>
<!-- mapping 映射文件引入方式有两种 -->
<!-- 1单个文件引入 -->
<property name="mappingResources" value="com/icss/pojo/User.hbm.xml"></property>
<!-- 2 全部引入 -->
<!-- <property name="mappingDirectoryLocations" value="classpath:cn/icss/pojo"></property> -->
</bean>
<!-- 3配置dao -->
<bean name="userDao" class="com.icss.dao.impl.UserDaoImpl2">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 4配置service -->
<bean name="userService" class="com.icss.service.impl.UserServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>
<!-- 5配置action -->
<bean name="userAction" class="cn.icss.action.UserAction">
<property name="userService" ref="userService"></property>
</bean>
hibernate管理事务
<!--6配置事物分为三步走 -->
<!-- 6.1核心事物管理器 -->
<bean name="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 6.2配置通知 -->
