即使在批處理模式下完成后，Springboot行程也會繼續運行

我需要以批處理模式運行springboot應用程式。一旦行程完成，行程應該退出。我撰寫了一個模擬代碼來實作相同的目標，但即使在列印陳述句完成后，該程序也沒有完成，我必須手動中止該程序。

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        ApplicationContext applicationContext = SpringApplication.run(DemoApplication.class, args);
        Test test = applicationContext.getBean(Test.class);
        test.printTest();
    }

}

測驗類：

package com.example.demo.service;

import org.springframework.stereotype.Component;

@Component
public class Test{

    public void printTest(){
        System.out.println("Test class !");
    }

}

uj5u.com熱心網友回復：

它一直在運行，因為您使用的是 ApplicationContext。您應該關閉背景關系。您可以使用 ConfigurableApplicationContext 并呼叫 close() 方法。

ConfigurableApplicationContext applicationContext = SpringApplication.run(DemoApplication.class, args);
        Test test = applicationContext.getBean(Test.class);
        test.printTest();
        applicationContext.close();
