您好，请问您是怎样配置的？烦请截图上传，谢谢。

您好,本地测试,设计模式的视图下,跟您类似的配置没有问题哦.
请问您那边的视图是设么类型的视图呢?然后请问您的视图对应是否有记录存在?

我的也是设计模式的视图，过滤中没有写任何代码

您好,请问您那边在后台预览的时候是什么效果?
tomcat是否也会报错??

后台预览合适，tomcat中没有报错信息，但是我有一条记录，可是显示无数据，呵呵

您好，方便的话我远程帮您看看，QQ：654105893

通过使用客户的数据，该问题已经重现，稍候会把问题整理并转交给研发，对您带来的不便表示歉意

嗯，希望你能把优先级放到最高，因为我的项目特别急，今天客户催我呢
