You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set:

  struts.devMode=false

in your WEB-INF/classes/struts.properties file.

出现这个问题的原因，是因为配置文件设置了当前的模式为开发模式，如

struts.xml

<constant name="struts.devMode" value="true"/>

将value设置为false就可以了；

 

如果设置为false还是不行，应该是你的异常处理采用了struts来处理，如

<global-results>              
            <!-- 异常结果 -->
            <result name="exception">/nodata.jsp</result>
            <result name="sqlException">/sqlException.jsp</result>
        </global-results>
       
        <!-- 异常处理 -->
        <global-exception-mappings>
         <exception-mapping result="exception" exception="java.lang.Exception"></exception-mapping>
         <exception-mapping result="sqlException" exception="java.lang.SQLException"></exception-mapping>
                 </global-exception-mappings>

 这个对于大部分的异常，都能够拦截处理，那是因为请求已经进入了

拦截器（Interceptor）或action，然后才出现的异常；但是对于某些情况，

请求只进入到了StrutsPrepareAndExecuteFilter，并没有进入到

拦截器（Interceptor）或action，就出现异常了，源码如下

 public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest request = (HttpServletRequest) req;
        HttpServletResponse response = (HttpServletResponse) res;

        try {
            prepare.setEncodingAndLocale(request, response);
            prepare.createActionContext(request, response);
            prepare.assignDispatcherToThread();
   if ( excludedPatterns != null && prepare.isUrlExcluded(request, excludedPatterns)) {
    chain.doFilter(request, response);
   } else {
    request = prepare.wrapRequest(request);
    ActionMapping mapping = prepare.findActionMapping(request, response, true);
    if (mapping == null) {
     boolean handled = execute.executeStaticResourceRequest(request, response);
     if (!handled) {
      chain.doFilter(request, response);
     }
    } else {
     execute.executeAction(request, response, mapping);
    }
   }
        } finally {
            prepare.cleanupRequest(request);
        }
    }

 当执行execute.executeAction(request, response, mapping)时，出现了异常，

struts的异常处理机制就处理不了了 ，

解决办法：

在web.xml中配置异常处理机制，如下：

<error-page>
  <exception-type>java.lang.Exception</exception-type>
  <location>/nodata.jsp</location>
 </error-page>
 
 <error-page>
  <error-code>404</error-code>
  <location>/404.jsp</location>
 </error-page>
 <error-page>
  <error-code>505</error-code>
  <location>/505.jsp</location>
 </error-page>
