springBoot: 启动Tomcat失败

Problem1：

SpringBoot启动Tomcat失败：[StandardEngine[Tomcat].StandardHost[localhost]

Solution：

原因是挂了SSR，ip地址跳转到了境外的原因！

解决方案：

进入Tomcat的目录，“手动启动” 之后再 “手动关闭” Tomcat服务器。
之后cmd，ping localhost ，如果成功则说明SSR已彻底关闭可使用！

修正： 观察ActiveMQ和redis命令行的状态，如有异常，关闭重启即可！

Problem2：

启动Tomcat报错:

java.lang.IllegalStateException: Illegal access: this web application instance has been stopped already. Could not load []. The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access.

Solution2：

在IDE中关闭Tomcat后，有些线程还未被杀死，所以，需要手动关闭/重启Tomcat！
