关于修改URL导致Struts Problem Report能否跳转到errorPage的问题

零下疯度 2014-12-21 08:16:41
最近做一个购物网站的项目，在一些页面跳转的过程中url会暴露出id等信息，在修改url中的id后页面会报空指针，因为id修改了，后台action取不到了，针对这个情况，能否让页面跳转到errorPage上面，如果给用户出来一堆空指针错误提示，显得不是很友好。希望大家给给意见。
url范例：http://localhost:8080/WSstore/memCenter/buy_toPayAccount.do?id=ab763fd7-3864-497e-9969-ecce8b7c5e8a
删除末尾a之后跳转页面触发错误，页面提示信息如下：
Struts Problem Report

Struts has detected an unhandled exception:

比如说页面出现400.404等错误可以通过配置跳转到errorPage，这种空指针异常信息能否也跳转到相应的错误页面呢？
