首先配置好struts2的过滤器:web.xml中的配置
<filter>
<filter-name>struts-prepare</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts-prepare</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
然后在<url-pattern>/*</url-pattern>后加上
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
就可以了...
