Spring Boot应用程序启动后立即关闭

使用Spring Boot框架开发应用程序可以极大地提高开发效率和简化配置过程。然而，有时候我们可能希望在应用程序启动后立即关闭，例如在测试过程中或者在某些特定场景下。本文将介绍如何在Spring Boot应用程序启动后立即关闭，并提供一个案例代码来演示。

xml
    
        org.springframework.boot
        spring-boot-starter-web
    

java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@RestController
public class Application {
    @GetMapping("/")
    public String home() {
        return "Hello, World!";
    }
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

java
SpringApplication app = new SpringApplication(Application.class);
app.run(args);
app.close();

java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(Application.class);
        ConfigurableApplicationContext context = app.run(args);
        context.close();
    }
}
