关于ERROR LazyInitializationException:19 - could not initialize proxy - no Session的错误;

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
