我先描述一下，我的项目上有登录过滤器，如没有登录，直接返回登录页面，现有需求，做一个不需要登录的查询页面，能直接访问，请问怎么整一下。是修改web.xml吗？
还有就是我现在web.xml，我不清楚哪项配置，控制了登录拦截，，请指教。 现在的web.xml内容如下：
<?xml version="1.0" encoding="UTF-8"?>

要么在web.xml中过滤器filter-mapping中不过滤那个页面。
要么在filter中做特殊处理（遇到那个页面，直接跳过filter）

如果你用jsf的话，最好使用phaselistener 进行角色控制。filter不符合jsf的生命周期规范。
