tags: 解决错误

今天在做SSH项目的时候，出现了这个错误。百思不得其解，网上的答案都不能解决我的问题.....

后来，一气之下就重新写，写了之后发现在JSP遍历集合的时候出错了。

最后发现是Hibernate懒加载的问题，在配置文件中设置不懒加载，就解决掉这个问题了。

二次更新: 我把getContextMap()换成是getApplicatoin()，也会出现这样的错误....

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

留意域对象有没有错误！
