4.Spring如何与struts2结合

1. Struts2的action由Spring来负责进行实例化

Struts.xml
    <!-- 指定Struts 2默认的ObjectFactory Bean，该属性默认值是spring -->
<constant name="struts.objectFactory" value="spring"/>
<!-- 该属性指定整合Spring框架时，是否缓存Bean实例，该属性只允许使用true和 false两个属性值，它的默认值是true。通常不建议修改该属性值 -->
<constant name="struts.objectFactory.spring.useClassCache" value="true"/>
<!-- 指定spring框架的装配模式装配方式有: name, type, auto, and constructor (name 是默认装配模式)  -->
<constant name="struts.objectFactory.spring.autoWire"
value="name"/>

2. 项目启动时由装载Spring

Web.xml
<listener>
    <listener-class>
org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>


3. 配置多个applicationContext.xml配置文件

applicationContext.xml
/*
*  在com/syy文件夹下以applicationContext开头的xml文件都将被加载进去
*/
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
classpath*:com/syy/applicationContext*.xml
</param-value>
</context-param>
