我正在使用inbuild tomcat服务器构建一个非常基本的spring-boot服务。春季启动内置tomcat服务器不启动

我在application.properties
文件server.port=8089
设置端口。有一个平URI在控制器类添加为:
@RequestMapping("/ping")
@RestController
public class helloController {
@RequestMapping(method= RequestMethod.GET,produces = {MediaType.APPLICATION_JSON_VALUE})
public ResponseEntity<String> ping(){
return new ResponseEntity<>("Hello World Spring-boot app", HttpStatus.OK);
}
当我做了mvn clean package
一切正常,并构建是成功的。但是,当我从Main()
运行应用程序,这是什么日志的样子:

日志没有显示什么端口的服务正在启动。
还有什么要做,以启动指定端口上的服务,并保持服务器运行?
对于初学者,删除'spring-web'依赖项。删除编译器插件并重新添加'spring-boot-maven-plugin'。另外你如何运行'main'方法?命令行? IDE?或者?... –
告诉你什么,尽管它没有真正相关,但我会尽快从代码中删除lombok。这是一个残酷的想法。 –
@ M.Deinum - 根据你的建议重新添加了spring-boot-maven -plugin,这次通过** spring-boot:start **选项启动服务器。现在在日志中,我看到应用程序从端口8089开始,但服务器再次停止。 – worrynerd
