ssh 整合 （spring + Struts2 + hibernate)

1.配置spring 初始化监听器

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
<!-- 修改request and response 字符 -->
<filter>

<filter-mapping>
<filter-name>CharsetFilter</filter-name>

</filter>
<filter-mapping>

<filter-name>Verification</filter-name>
<url-pattern>/interceptor-jsp/*</url-pattern>
<!-- 过滤服务器url -->
<dispatcher>INCLUDE</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
</filter-mapping>

<!-- struts2 过滤器 -->
<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>
<!-- 配置全局参数   -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-ssh.xml</param-value>
</context-param>
<!-- 配置spring 初始化监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

</web-app>

2.配置jdbc.properties

user=bookmanager
password=test
driver=oracle.jdbc.driver.OracleDriver
url=jdbc\:oracle\:thin\:@localhost\:1521\:orcl

3.配置spring-ssh.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans  xmlns = "http://www.springframework.org/schema/beans"
xmlns:aop = "http://www.springframework.org/schema/aop"
xmlns:context = "http://www.springframework.org/schema/context"
xmlns:tx = "http://www.springframework.org/schema/tx"
xmlns:instance = "http://www.w3.org/2001/XMLSchema-instance"
instance:schemaLocation = " http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/tx 
103a7 http://www.springframework.org/schema/tx/spring-tx-4.1.xsd "
>
<!-- 配置组件扫描器 -->
<context:component-scan base-package="com.book.manager.*">
</context:component-scan>

<!-- 配置外部资源引用文件 -->
<context:property-placeholder location="classpath:jdbc.properties"/>

<!-- 配置数据源 -->
<bean id = "dataSource" class = "org.apache.commons.dbcp.BasicDataSource" >
<property name="url" value="${url}"></property>
<property name="username" value="${user}"></property>
<property name="password" value="${password}"></property>
<property name="driverClassName" value="${driver}"></property>
</bean>

<!-- 配置hibernate sessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" >
<!-- 注入数据源 -->
<property name="dataSource" ref="dataSource"></property>
<!-- 注入关系映射文件 -->
<property name="mappingResources">
<list>
<value>com/book/manager/entity/bookEntityOrm.xml</value>
<value>com/book/manager/entity/userEntityOrm.xml</value>
</list>
</property>
<!-- 注入hibernate 的属性配置 -->
<property name="hibernateProperties">
<props>
<!-- console 显示 sql 语句 -->
<prop key="show_sql">true</prop>
<!-- 格式化sql 语句，可读性更直观 -->
<prop key="format_sql">true</prop>
<!-- 设置数据库要使用的方言 -->
<prop key="dialect">
org.hibernate.dialect.Oracle10gDialect
</prop>

</props>
</property>

</bean>

<!--  配置hibernate 模板 -->
<bean id = "hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate" >
<!-- 注入sessionFactory -->
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<!-- 配置hibernate 事务管理器，让spring来管理事务 -->
<bean id = "transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager" >
<property name="sessionFactory" ref="sessionFactory"></property>
<property name="dataSource" ref="dataSource"></property>
</bean>

<!-- 定义事务通知 -->
<tx:advice id="txAdivse" transaction-manager="transactionManager" >
<tx:attributes >
<tx:method name="add*" isolation="DEFAULT" propagation="REQUIRED" timeout="2" rollback-for="java.lang.Exception" />
<tx:method name="update*" isolation="DEFAULT" propagation="REQUIRED" timeout="2" rollback-for="java.lang.Exception"/>
<tx:method name="delete*" isolation="DEFAULT" propagation="REQUIRED" timeout="2" rollback-for="java.lang.Exception"/>
<tx:method name="*" read-only="true" />
</tx:attributes>
</tx:advice>

<!-- aop 切面 -->
<aop:config>
<aop:pointcut expression ="execution(* com.book.manager.service.*.*(..))" id="pointCut"/>
<aop:advisor advice-ref = "txAdivse" pointcut-ref="pointCut"/>
</aop:config>

</beans>

4.把管理权给予spring

<?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.action.extension"  value="action,do"/>
<!-- 让 sping 来管理控制 -->
<constant name="struts.objectFactory" value="spring"></constant>
</struts>

5.所有DaoImpl继承 hibernateDaoSupper

package com.book.manager.dao;

import javax.annotation.Resource;

import org.apache.log4j.Category;
import org.apache.log4j.Logger;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate4.HibernateTemplate;
import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
// 所以 dao 层的实现类必须继承 hibernateDaoSupport
//这里继承SuperDao 就 可以通过getSeeion 来获取session
public class SuperDao extends HibernateDaoSupport {
@Resource(name="hibernateTemplate")
public void setChildHibernateTemplate(HibernateTemplate template){
logger.debug("----> " + template);
//设置父类的hibernateTemplate
super.setHibernateTemplate(template);
}
@Resource(name="sessionFactory")
public void setChildSessionFactory(SessionFactory sessionFactory){
//设置父类的sessionFactory
super.setSessionFactory(sessionFactory);
}
public Session getSession(){
logger.debug("----> "+this.getClass().getName());
logger.debug("----> 1"+getHibernateTemplate());
logger.debug("----> 2"+getHibernateTemplate().getSessionFactory());
logger.debug("----> 3"+getHibernateTemplate().getSessionFactory().getCurrentSession());
return getHibernateTemplate().getSessionFactory().getCurrentSession();
//return getSessionFactory().getCurrentSession();
}
}
