SpringBoot Application Exiting Time

Every single time when i'm exiting my program, I have to wait a minute to shutdown the application. (I am currently using Spring Initalizr to get project skeleton & Spring's extra classes.) enter image description here So, the project is total empty except the output you see and folders (and json files in resources). This is the xml.pom file.

I have controller class: enter image description here

I couldn't find any solution to this problem in my IDE (IntelliJ Ultimate).

I will be glad to get helped! : )

Solution

  • This problem is related to spring-data-jpa . If you initialize spring-data-jpa, it keeps alive the application for at least 60 seconds before shutdown hook is invoked. I did not find the reason.

    One workaround is shutdown the application manually.

    @Autowired
ConfigurableApplicationContext applicationContext;

@Override
public void run(String... args){
    applicationContext.close();
}
