Spring如何与struts2结合

4.Spring如何与struts2结合

关键字: 4

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>
