从maven-Plugins-tomcat7-tomcat7:run启动的
IDEA2020.1
maven3.5.2
jdk1.8
IDEA右键没有 properties
求大佬帮助

Answer 1

项目启动是报错：
org.springframework.web.context.ContextLoaderListener

解决方法：

右键单击工程项目 ->点击 properties
选择 Deployment Assembly
点击 Add -> Java Build Path Entries -> Next
选择 Maven Dependencies -> Finish -> Apply -> OK
Clean project and server. 重启server
