You can add the Shutdown hook in my application.

Java shutdown hook runs in these two cases.

  • The program exits normally, or we call System.exit() method to terminate the program. Read more about Java System Class.
  • User interrupts such as Ctrl+C, system shutdown etc.

Code:

Runtime.getRuntime().addShutdownHook(new Thread("Shutdownhook") {
            public void run() {
                //code here
                //compare redis cache  
                //syn data and save local file.  
                try {
                    mainThread.join();
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    instance.logger.error(e.getMessage(), e);
                }
            }
        });

Incase if you are using spring-boot-devtools dependency in your pom.xml file, when any new changes are made to existing project it will automatically restart the project. It helps in cases where on making minor changes, the project is automatically restarted and the application start time is also significantly small compared to normal scenario. If you don't wish to have this behavior you can just remove the following dependency from you pom.xml file, thereby there is no automatic restart of application.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <optional>true</optional>
 </dependency>
