如何以正确的方式关闭Spring Boot应用程序？

@SpringBootApplication
public class MyApplication {
    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(MyApplication.class, args);
        
        // 在某个条件满足时关闭应用
        if (shouldShutdown()) {
            SpringApplication.exit(context);
        }
    }
    
    private static boolean shouldShutdown() {
        // 实现你的关闭逻辑
        return false;
    }
}

@SpringBootApplication
public class MyApplication {
    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(MyApplication.class, args);
        
        Runtime.getRuntime().addShutdownHook(new Thread(() -> {
            System.out.println("Shutting down application...");
            context.close();
        }));
    }
}

@Service
public class MyService {
    @PreDestroy
    public void cleanup() {
        System.out.println("Cleaning up resources...");
        // 释放资源
    }
}
