已采纳

你将PUSH到服务器的war放到目录后，手动解压一下，然后重启服务器看看。

【mysql8的驱动jar包】我突然发现服务器上的war包里面的mysql驱动jar包还是5点几。 ||| 于是我想通过gradle依赖下载最新的驱动jar包，但是idea下载不了。我从其他途径下载了mysql-connector-java-8.0.19，传输到服务器上，然后拷贝到对应的webapps-italker/ROOT/WEB-INF/lib/下面。 ||| 重启tomcat后，访问index.jsp直接404。 ||| 心态炸裂。老师，我能不能在qq发你远程登录的账户和密码，您能不能帮我上去看一看？？？ o(╥﹏╥)o
