**错误信息如上。
tomcat8 jdk1.8

tomcat eclipse jdk 所有环境都是 新装的 运行其他项目没有任何问题。
maven构建项目 jar包都是正常导入 项目没有显示任何错误。
找了很久还是不知道什么原因造成的。如果需要其他信息 请留言。
谢谢各位~~

Answer 1

G:Serversapache-tomcat-8.0.39confCatalinalocalhostWebApplication1.xml What content has been changed

Answer 2

I answered a person’s question last time. If you use the troubleshooting method, first clear all your projects and see if there is any problem with starting tomcat again. If there is any problem, it is recommended that you replace tomcat. If not, you need to check the deployment project. If there is no problem with your web.xml file, check your spring-related files because it plays the role of a listener and will be instantiated when it is started. I think there should be a problem with your WebApplication1.xml

Answer 3

Is the installation path to tomcat correct?
