我在jsp 页面总是出现这个错误原来以为是hibernate 的错误; 每次跳转的时候都会报错; 我以为是hibernate 的问题; 有时候会提示什么structs json 错误;

郁闷了半天; 后来看到structs json 错误; 发现方法配置错误了;

    <action name="findQuestionByIndexAction" class="question"
           method="findQuestionByIndex" >
            <result type="json">
           /front/exercise/exercise00.jsp
   </result>

原来是返回json 对象; 后来是进行转发;

把 type="json"去掉

改为    <action name="findQuestionByIndexAction" class="question"
           method="findQuestionByIndex" >
            <result>
           /front/exercise/exercise00.jsp
   </result>

就不报错了
