Tomcat启动报错 Failed to start component [StandardServer[8005]]解决

Posted 2020-06-19 亲爱的村姑

SEVERE: The required Server component failed to start so Tomcat is unable to start. org.apache.catalina.LifecycleException: Failed to start component [StandardServer[8005]]

之前在Eclipse上部署了Tomcat服务器，今天在MyEclipse上部署，结果Tomcat启动失败，报错。在网上搜了半天，有的说是因为端口被占用，有的说因为Tomcat的JDK版本不对。其实都不是。原因是Tomcat的server.xml配置文件最后多出来的这几行，估计是以前在Eclipse上跑的项目自动生成的。把它们删了之后Tomcat就正常运行了。
