dojo

struts2.1.X结合使用dojo：
struts2.0及以前，其对dojo的ajax支持是放在struts2-core-2.0.X.jar包中的；
struts2.1后，默认的dojo ajax支持被从core包中抽出放入了struts2-dojo-plugin-2.1.8.jar中。网上2.0及之前版本与dojo的结合例子多的是，这里说下2.1.8.1配置dojo：

Reference the new taglib in your JSP or FTL pages.
Before （2.0的用法）

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags"%>

After （2.1及之后的用法）

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>

Update the head tag
Before:

<s:head theme="ajax"/>

After:

<sx:head parseContent="true"/>

The web.xml before (matching all requests):

<filter>
	<filter-name>struts2</filter-name>
	<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>

<filter-mapping>
	<filter-name>struts2</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

Change to use the new StrutsPrepareAndExecuteFilter and match just struts requests.

The web.xml after:

<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>*.action</url-pattern>
</filter-mapping>

<filter-mapping>
	<filter-name>struts2</filter-name>
	<url-pattern>/struts/*</url-pattern>
</filter-mapping>

Well, that won't work well unless you've extracted the static files out of the Struts jar.

As the S2 documentation states, the expected filter mapping is "/*". This is because Struts contains static files (the Dojo libraries, in this case), and expects to see *every* request, so it can serve those files.

By mapping to something other than the recommended mapping you're bypassing the default S2 behavior, and must adjust your deployment accordingly.
