Answer 1

在web.xml没有这种配置，猜测是最后session-config这里的配置使session失效，验证跳转到登陆页

Answer 2

优先考虑session超时导致的首页跳转

1. tomcat的conf/web.xml可以配置，<session-config>标签，一般是30分钟
2. 项目的web.xml里面可以配置<session-config>标签，你给的里面配的是3000，单位是分钟
3. java代码可以通过session.setMaxInactiveInterval来配置session超时
4. 项目里面代码有相关的过滤拦截，你这里有一个checkLoginFilter，看一下里面有没有做判断
   优先级上 4>3>2>1
