1、严重: Exception sending context initialized event to listener instance of class ch.qos.logback.ext.spring.web.LogbackConfigListener
java.lang.IllegalStateException: Web app root system property already set to different value: 'springmvc.root' = [C:\Users\15057\Downloads\entertainmentSoftware\SoftWare\jdk\javaWorkSpace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\crs\] instead of [C:\Users\15057\Downloads\entertainmentSoftware\SoftWare\jdk\javaWorkSpace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\drs\] - Choose unique values for the 'webAppRootKey' context-param in your web.xml files!
2、这是因为启动了crs、drs两个项目，web.xml中webAppRootKey无法识别
3、在Add and Remove中可以看到Tomcat启动了两个项目，本次启动是为了查看drs项目
4、移除暂时不用的crs项目
5、重新启动Tomcat，如图所示启动成功
6、测试项目可正常访问
