因为会报红如下所示信息，一直百度搜索如下关键字，大部分都是jdk配的不对，没解决问题

 后来注意到第一行如下提示

Identify and stop the process that's listening on port 8080 or configure this application to listen on another port.

报的是端口错误，想着有可能是端口的原因，修改端口如下，编辑src/resources/application.properties文件

server.port=9099

在控制台执行如下命令，清理下缓存

./mvnw clean install

重启服务

./mvnw spring-boot:run -X

效果如下，可以正常访问了
