java.io.IOException: Stream closed

今天在作SSH項目的時候，出現了這個錯誤。百思不得其解，網上的答案都不能解決個人問題…..

後來，一氣之下就從新寫，寫了以後發如今JSP遍歷集合的時候出錯了。

<s:iterator value="rolePrivilegeSet">
           <s:property value="#privilegeMap[compositeKey.code]"/>
        </s:iterator>

最後發現是Hibernate懶加載的問題，在配置文件中設置不懶加載，就解決掉這個問題了。

二次更新:
我把getContextMap()換成是getApplicatoin()，也會出現這樣的錯誤….

ActionContext.getContext().getContextMap().put("privilegeMap", Constant.PRIVILEGE_MAP);

留意域對象有沒有錯誤！
