spring3.1集成struts2.1.6配置文件集成

【引言】 本来spring就有mvc，可是大家用struts习惯了，最近用spring来管理后台dao，struts2来响应请求。面对一大堆的配置文件，classes路径下一堆， /WEB-INF/下一堆，很分散，看着也不爽。于是就想把他们放在一起。

1、配置文件及位置分布：

log4j.properties    src目录下

spring相关配置文件： src/config/spring/*.xml

    

     applicationContext.xml  src/config/spring/applicationContext.xml

     applicationContext-action.xml   src/config/spring/applicationContext-action.xml 

     applicationContext-dao.xml      src/config/spring/applicationContext-dao.xml

     applicationContext-service.xml   src/config/spring/applicationContext-service.xml

struts相关配置文件： src/config/struts/*.xml

     struts.xml src/config/struts/struts.xml

     struts_query.xml   src/config/struts/struts_query.xml

     struts_common.xml  src/config/struts/struts_common.xml

2.web.xml文件

<?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">

	<!-- 用于初始化Spring的Listener -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 设置Spring的log4j监听器 -->
	<listener>
		<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
	</listener>

	<!-- Spring核心配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
    		classpath:config/spring/applicationContext.xml,
    		classpath:config/spring/applicationContext-*.xml
    	</param-value>
	</context-param>	

	<filter>
		<filter-name>struts2-prepare</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
		<init-param>
			<param-name>config</param-name>
			<!--  config files for struts2, struts-default.xml, struts-plugin.xml can't delete -->
			 <param-value>
			 	struts-default.xml,
			 	struts-plugin.xml,
			 	/config/struts/struts.xml
			 </param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>struts2-prepare</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<filter>
		<filter-name>struts2-execute</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>struts2-execute</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<filter>
		<filter-name>struts-cleanup</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>struts-cleanup</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
	<welcome-file-list>
		<welcome-file>login.jsp</welcome-file>		
	</welcome-file-list>
	
</web-app>

说明：

1、要是struts.xml文件不放在默认的src文件夹下，需要增加struts-default.xml, struts-plugin.xml两个配置文件。然后在需要配置的Filter下增加以下参数：

<init-param>
			<param-name>config</param-name>
			<!--  config files for struts2, struts-default.xml, struts-plugin.xml can't delete -->
			 <param-value>
			 	struts-default.xml,
			 	struts-plugin.xml,
			 	/config/struts/struts.xml
			 </param-value>
		</init-param>

2、没有使用  ActionContextCleanUp Filter的话，直接配置 PrepareAndExecuteFilter就ok了。

 <filter>
	<filter-name>struts2</filter-name>
	<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
	<init-param>
		<param-name>config</param-name>
		<!--  config files for struts2, struts-default.xml, struts-plugin.xml can't delete -->
		 <param-value>
		 	struts-default.xml,
		 	struts-plugin.xml,
		 	/config/struts/struts.xml
		 </param-value>
	</init-param>
</filter>
<filter-mapping>
	<filter-name>struts2-prepare</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

若已经使用了 ActionContextCleanUp  Filter的话，需同时配置两个如下Filter。

<filter>
	<filter-name>struts2-prepare</filter-name>
	<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
	<init-param>
		<param-name>config</param-name>
		<!--  config files for struts2, struts-default.xml, struts-plugin.xml can't delete -->
		 <param-value>
		 	struts-default.xml,
		 	struts-plugin.xml,
		 	/config/struts/struts.xml
		 </param-value>
	</init-param>
</filter>
<filter-mapping>
	<filter-name>struts2-prepare</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

<filter>
	<filter-name>struts2-execute</filter-name>
	<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
</filter>
<filter-mapping>
	<filter-name>struts2-execute</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

<filter>
	<filter-name>struts-cleanup</filter-name>
	<filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>
</filter>
<filter-mapping>
	<filter-name>struts-cleanup</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>
