Springboot process keeps running even after completion in batch mode-CodePudding

I need to run the springboot application in the batch mode. As soon as the processes get finished, the process should exit. I have written a mock code to achieve the same but even after the print statement is completed, the process is not getting completed and I have to manually abort the process.

@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();
    }

}

Test.class :

package com.example.demo.service;

import org.springframework.stereotype.Component;

@Component
public class Test{

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

}

CodePudding user response：

It keeps running because you are using an ApplicationContext. You should close the context. You can use ConfigurableApplicationContext and call the close() method .

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