Spring Boot App在启动时终止 [英] Spring Boot App Terminating at Startup

问题描述

我正在尝试一个简单的spring启动应用程序，它总是自动关闭

主类

  @SpringBootApplication 
 public class RestBootApplication {
 
 public static void main（String [] args）{
 SpringApplication.run（RestBootApplication.class，args）; 
} 
} 
  

控制器

  @Controller 
 public class HelloController {
 
 @RequestMapping（/ hello）
 String helloWorld（）{
返回helloWorld; 
} 
 
} 
  

尝试在spring工具套件中运行。它总是在开始后停止。在查看了一些stackoverflow问题之后，我甚至添加了spring-boot-starter-web，但仍然面临着这个问题。

请你指点一下这个问题。

解决方案

这发生在我身上，结果证明是一个损坏的maven apache存储库。

要修复它，我删除了apache repo - 在我的Mac上，它位于/Users/myname/.m2/repository/org/apache。

在电脑上它应该是c：\ usersrs \myname.m2 \\\ store \\\\\\\\\\\\\\\\\\\ b $ b

然后我运行了Maven - 更新项目，然后我运行了我的课程并修复了它。

Main Class

@SpringBootApplication
public class RestBootApplication {

    public static void main(String[] args) {
        SpringApplication.run(RestBootApplication.class, args);
    }
}

Controller

@Controller
public class HelloController {

    @RequestMapping("/hello")
    String helloWorld(){
        return "helloWorld";
    }

}

Trying to run in spring tool suite. it always stops after starting. I even added "spring-boot-starter-web" after looking at some stackoverflow questions, but still facing the issue.

Please can you someone point out the issue.

解决方案

This was happening to me and it turned out to be a corrupted maven apache repository.

To fix it I removed the apache repo - on my Mac it was located at /Users/myname/.m2/repository/org/apache.

On a pc it should be c:\users\myname.m2\repository\org\apache.

I then ran Maven - Update Project and then I ran my class and it was fixed.
