Ways for Clean Shutdown of Spring Boot Applications, whether in Developer mode or in Production Mode. Code Samples are provided Inline and via Git Repo. - springboot springbootshutdown
For the last 3-4 years, I have been working on Spring Boot and its associations like Spring Cloud, Spring Data and Spring Security. I have always been tempted to use the combination of [Ctrl+C] and [taskkill] for the purpose of killing spring boot applications or processes.
This is a very convenient way especially if you are a Software Architect or an Engineer who has lots of Microservices to develop/manage/maintain. It will be useful when you are in depths of testing/debugging/fixing.The most 'cleanest' way among the ones I described until now is the usage of Actuator to shutdown the spring boot applications.
The application context needs to be stored when you start/run the spring boot application in your spring boot application class. // Starting Threads using Runnable is Not Always the Best Way.. // Do Explore Other Integrated Approaches such as Async Servlet @RequestMapping public ResponseEntity rule { System.out.println: " + Thread.currentThread.getName); Runnable runnable= -> { try { Thread.sleep; } catch { System.out.println"); } System.out.println.getName); SpringBootDockerApplication.ctx.close; }; new Thread.start; System.out.println: " + Thread.currentThread.
// Clean Shutdown Method 2 - Actuator Shutdown Endpoint - Store the Context // Not a Recommended Way to Use public static - Only for the Demo Purposes.. private static ConfigurableApplicationContext ctx; public static void main { // Clean Shutdown Method 2 - Actuator Shutdown Endpoint - Store the Context ctx=SpringApplication.run; } public static void exitApplication { int staticExitCode=SpringApplication.exit { @Override public int getExitCode { // no errors return 0; } }); System.
