SSH整合

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

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.xml 【公用信息】

web.xml

<?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">
    <display-name></display-name>

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

    
        Spring配置，在服务器启动时创建
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:bean*.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

        Struts2配置
    <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>

struts2常量配置

<?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>

    <!-- 0，修改接收参数和页面编码 (默认为:UTF-8, 所以这项可以不用设置) -->
    <constant name="struts.i18n.encoding" value="UTF-8"></constant>

    <!-- 1，修改struts的默认访问后缀 struts.action.extension=action,, -->
    <constant name="struts.action.extension" value="action,do,"></constant>

    <!-- 2，当struts配置文件修改时是否自动重新加载该文件，开发条件下开启，生产阶段关闭 struts.configuration.xml.reload=false 
        默认关闭 -->
    <constant name="struts.configuration.xml.reload" value="true"></constant>

    <!-- 3，设置浏览器是否自动缓存静态内容，生产模式开启，开发模式关闭 struts.serve.static.browserCache=false -->
    <constant name="struts.serve.static.browserCache" value="false"></constant>

    <!-- 4，设置上传文件大小限制 struts.multipart.maxSize=2097152 -->
    <constant name="struts.multipart.maxSize" value="100000000"></constant>

</struts>

Action配置

<?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="emp" extends="struts-default">
    
        <action name="test" class="action.UserAction" method="insert">
            <result name="success">/success.jsp</result>
        </action>
        
    </package>
    
    <include file="struts.xml"></include>
     
</struts>

Spring自动装配和hibernate的SessionFactory配置（其中连接池交给spring)

        </property> -->
    </bean>
    
    <!-- ####################spring与hibernate整合######################## -->
    
    <!-- 4，事务管理配置 -->
     <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="*" read-only="false"/>
            <tx:method name="get*" read-only="true"/>
        </tx:attributes>
    </tx:advice>
    <aop:config>
        <aop:pointcut expression="execution(* service..*(..))" id="pt"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
    </aop:config>
    
</beans>

dao service 和action使用注解自动装配
