strust2 2.0.4版本中验证返回类型为chain时执行action配置
struts2 2.0.4中 修改defaultStack，将chain拦截器放到最后
<interceptor-ref name="exception"/> <interceptor-ref name="alias"/> <interceptor-ref name="servletConfig"/> <interceptor-ref name="prepare"/> <interceptor-ref name="i18n"/> <interceptor-ref name="debugging"/> <interceptor-ref name="profiling"/> <interceptor-ref name="scopedModelDriven"/> <interceptor-ref name="modelDriven"/> <interceptor-ref name="fileUpload"/> <interceptor-ref name="checkbox"/> <interceptor-ref name="staticParams"/> <interceptor-ref name="params"> <param name="excludeParams">dojo\..*</param> </interceptor-ref> <interceptor-ref name="conversionError"/> <interceptor-ref name="validation"> <param name="excludeMethods">back,cancel,browse</param> </interceptor-ref> <interceptor-ref name="workflow"> <param name="excludeMethods">back,cancel,browse</param> <!-- 把chain放到最后 --> </interceptor-ref> <interceptor-ref name="chain"/>
<result name="input" type="chain"><param name="namespace">/</param><param name="actionName">updatePUser</param><param name="method ">abc</param></result>
?则会验证失败时会显示错误消息，同时会显示执行chain - action中的方法
