我正在尝试一个简单的 spring boot 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);
    }
}

Controller

@Controller
public class HelloController {

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

}

尝试在 spring 工具套件中运行。它总是在启动后停止。在查看了一些 stackoverflow 问题后，我什至添加了“spring-boot-starter-web”，但仍然面临这个问题。

请有人指出这个问题。

最佳答案

在我的例子中，只是将以下内容添加到 pom 文件中

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

关于java - Spring Boot 应用程序在启动时终止，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40205600/
