在web.xml沒有這種配置，猜測是最后session-config這里的配置使session失效，驗(yàn)證跳轉(zhuǎn)到登陸頁

優(yōu)先考慮session超時(shí)導(dǎo)致的首頁跳轉(zhuǎn)

tomcat的conf/web.xml可以配置，<session-config>標(biāo)簽，一般是30分鐘
項(xiàng)目的web.xml里面可以配置<session-config>標(biāo)簽，你給的里面配的是3000，單位是分鐘
java代碼可以通過session.setMaxInactiveInterval來配置session超時(shí)
項(xiàng)目里面代碼有相關(guān)的過濾攔截，你這里有一個(gè)checkLoginFilter，看一下里面有沒有做判斷
優(yōu)先級(jí)上 4>3>2>1
