Gracefull shutdown for Spring boot Application

Question

Я запускаю приложение для загрузки весны, и все хорошо, за исключением случаев, когда я пытаюсь его закрыть. Я получил ошибку ниже код

while (true) { 
     try { 
      if(level2List == null) 
       break; 
      CDR cdr = level2List.poll(2, TimeUnit.SECONDS); 

генерируется ошибка на последней строке, весна ботинок выключая level2List до 2 вторых ждать сделано, как показано ниже

Есть ли способ заказать процесс закрытия или убедиться, что я не использую level2List, прежде чем отключать его?

Answer 1

Я две вещи

добавить

@Bean(destroyMethod = "shutdown") 
public ThreadPoolTaskExecutor level1ES() { 

также

} catch (InterruptedException e) { 
     log.warn("Closing application while CDR still in queue");   }
