启动Tomcat闪退 java.net.BindException: Address already in use: JVM_Bind

启动Tomcat闪退 java.net.BindException: Address already in use: JVM_Bind

问题：因为需求，需要将另一个tomcat上的项目迁移到另一个tomcat上，部署完毕之后启动tomcat闪退，查看catalina日志，查看报错信息

解决： 再看报错信息，初步怀疑是端口占用，但是在部署新的tomcat时，已经在server.xml中修改过tomcat端口，网上搜索问题端口被占用描述的是java.net.BindException: Address already in use: JVM_Bind+(端口)，但是如上错误并没有显示被占用的端口；然后发现是因为我是直接复制的上一个项目的tomcat，虽然修改了端口，但是还是不行；最后重新解压一个tomcat即可。
