I want to gracefully shutdown my spring boot application. I wanted to know what is the difference between configuring it via application.yaml file and programmatically ?
in my application yaml file, i have added this from reference https://www.baeldung.com/spring-boot-web-server-shutdown:
server:
shutdown: graceful
spring:
lifecycle:
timeout-per-shutdown-phase: 30s
and in my code i am also using threadPoolTaskExecuter because I am using @EnableAsync annotation:
@Bean("threadPoolTaskExecutor")
public TaskExecutor getAsyncExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(20);
executor.setMaxPoolSize(200);
executor.setWaitForTasksToCompleteOnShutdown(true);
executor.setAwaitTerminationSeconds(30);
executor.setThreadNamePrefix("async-");
executor.setQueueCapacity(50);
executor.initialize();
return executor;
}
where i added executor.setAwaitTerminationSeconds(30) so my question is do we need both ways to configure it or not? and what is the difference? Also I found that we have other configuration available from spring from here: Spring Boot: gracefully shutdown by controlling termination order involving MongoClient
spring.task.execution.shutdown.await-termination=true
spring.task.execution.shutdown.await-termination-period=60
this is confusing to me. Can someone please explain the different ways ? Thanks in advance
