本文介绍如何正确配置Struts2框架，包括在web.xml中设置字符编码过滤器、使用URL重写及解决文件上传问题等。文章详细展示了各种过滤器及其映射的配置示例。

在qieqie这里http://www.iteye.com/topic/53834

发现了一个好东西，但按照他这里在项目里配置发现不成功

今天在把之前在网上收集的资料找了下，找到答案

在struts的filter-mapping中加入以下就可以了

<filter-mapping> 
        <filter-name>struts2 </filter-name> 
        <url-pattern>*.do </url-pattern> 
        <dispatcher>REQUEST </dispatcher>  
        <dispatcher>FORWARD </dispatcher>  
       <dispatcher>INCLUDE </dispatcher>  
</filter-mapping>

如下：

<!-- Character Encoding filter -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>
			org.springframework.web.filter.CharacterEncodingFilter
		</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<!-- Hibernate Open Session In View filter-->
	<filter>
		<filter-name>osivFilter</filter-name>
		<filter-class>
			org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
		</filter-class>
	</filter>
	<!-- UrlRewriteFilter filter -->
	<filter>
		<filter-name>UrlRewriteFilter</filter-name>
		<filter-class>
			org.tuckey.web.filters.urlrewrite.UrlRewriteFilter
		</filter-class>
		<init-param>
			<param-name>logLevel</param-name>
			<param-value>WARN</param-value>
		</init-param>
	</filter>
		<!-- Struts2 filter -->
	<filter>
		<filter-name>struts2-cleanup</filter-name>
		<filter-class>
			org.apache.struts2.dispatcher.ActionContextCleanUp
		</filter-class>
	</filter>
		<filter>
		<filter-name>struts2</filter-name>
		<filter-class>
			org.apache.struts2.dispatcher.FilterDispatcher
		</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	
	<filter-mapping>
		<filter-name>osivFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<filter-mapping>
		<filter-name>UrlRewriteFilter</filter-name>
		<url-pattern>/*</url-pattern>
		<dispatcher>REQUEST</dispatcher>
		<dispatcher>FORWARD</dispatcher>
	</filter-mapping>


	<filter-mapping>
		<filter-name>struts2-cleanup</filter-name>
		<url-pattern>/*</url-pattern>
		<dispatcher>REQUEST</dispatcher>  
        <dispatcher>FORWARD</dispatcher> 
	</filter-mapping>

	<filter-mapping>
		<filter-name>struts2 </filter-name> 
        <url-pattern>/*</url-pattern> 
        <dispatcher>REQUEST</dispatcher>  
        <dispatcher>FORWARD</dispatcher> 
	</filter-mapping>

1、在web.xml中EncodingFilter的位置应该在Struts2的FilterDispatcher之前，道理很简单，要先调整字符集，再进入Action。

2、如果使用Urlrewrite，要指定filter-mapping的dispatcher方式，如下
<filter-mapping>
    <filter-name>Struts2</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

3、在做上传文件的时候，要在web.xml中增加ActionContextCleanUp这个filter，如果不增加，会发生第一次上传取不到文件的情况
<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>
按照Struts2的API，filter的顺序是
struts-cleanup filter
SiteMesh filter
FilterDispatcher
