推荐答案

Tomcat 8引用了 sun.misc.GC ，在Java 9中已将其删除-因此会出现错误.

Tomcat 8 references sun.misc.GC, which was removed in Java 9 - hence you get the error.

请不要告诉我尽可能降低版本，因为我喜欢使用最新技术.

Please don't tell me to decrease the version if possible, because I love to use latest technology.

那我就告诉你做相反的事情！您应该使用的是Tomcat 9，而不是Tomcat8.然后该错误应消失.

I'll tell you to do the opposite then! You should be using Tomcat 9, not Tomcat 8. The error should then disappear.
