您好，NullPointerException ，光看这个没办法判断是什么原因造成的。

后台登录正常，登陆后新建栏目和内容没问题，但之前建的点击开来会报下面的错。新建的过段时间也会报下面的错

，请问版主这是为什么呢？

上面的那个是日志。好像是geturl出的错，但是在我本地的tomcat上跑没问题，放上空间上就报这样的错了，后台登陆和其他部分功能都正常的，就栏目和内容会这样

光看这个异常没办法判断的了，您上传的时候选择了编码吗？

没有选择编码，就上传到ftp上，然后解压的代码。数据库是直接用mysql导出来再那边执行的，好像我这边用的是utf-8，那里用的是gbk，不知道有没影响，我先试试改成一致的数据库编码。但是我新建的都没问题，但是重启tomcat后又出现同样的问题了

有影响的，系统需要使用utf-8编码。上传的时候，有选择编码，那里也要选择utf-8编码

jsp容器的问题。我怀疑空间商的tomcat6的lib共享包部分和我工程下的lib包产生冲突，我切换成7.0就没问题了。怪不得在我本地都可以，上传上去就不行。从这句信息也印证这个问题：信息: The listener "org.springframework.web.context.ContextLoaderListener" is already configured for this context. The duplicate definition has been ignored. 
只是空间商的共享lib我无法看到

您可以联系下他们，看看具体是怎么样的。
