1、检查服务器启动的时候的后台日志，确认启动正常与端口正确
2、先使用FireFox连接服务器，如果不正确，将url-pattern中的内容改成如*.do，再重启服务器，使用Firefox连接服务器，看看是否正常，如果正常，则是filter中的内容异常。

我感觉，一般是你的服务器没有正常启动。应该是filter中发生异常了吧。
如果是filter异常，可以贴一下filter的代码。

把你怎樣添加的filter以及filter貼出來唄，不然你讓大家看什麼？

Answer 10

1、检查服务器启动的时候的后台日志，确认启动正常与端口正确
2、先使用FireFox连接服务器，如果不正确，将url-pattern中的内容改成如*.do，再重启服务器，使用Firefox连接服务器，看看是否正常，如果正常，则是filter中的内容异常。

我感觉，一般是你的服务器没有正常启动。应该是filter中发生异常了吧。
如果是filter异常，可以贴一下filter的代码。
