我解决了:右键单击JavaSe properties- CustomerManager Build Path - Librarires - JRE System LibrrariesJavaSe-13-编辑-将JavaSe-13更改为JavaSe-9 -finish -apply。
项目正在运行。但是为什么不使用JavaSe 13呢？

快速解决方案:如果您从集成开发环境(eclipse或intellij)运行，打开文件/.settings文件。查看标记的值：<property name="context-root" value=获取该值，该值是URL的根元素。例如:如果它是"abc"，那么你可以使用http://localhost:8082/abc/，如果值是其他值，则使用该值。
另一种选择是检查tomcat服务器下的server.xml下的值，并查看标记<Context docBase="abc" path="/abc"、take value of path和use in your URL。例如：http://localhost:8082/abc/
