设置 Spring Boot 的定时任务线程池以优雅退出

---

1、设置线程池

---

@Component
public class SchedulingPoolConfig 

  @Bean
  TaskScheduler taskScheduler()
    ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
    scheduler.setPoolSize(16);
    scheduler.setThreadNamePrefix("sc");
    scheduler.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
    scheduler.setWaitForTasksToCompleteOnShutdown(true);
    return scheduler;
  

2、置入线程池

---

@Component
public class SchedulingConfig implements SchedulingConfigurer 

  @Autowired
  private TaskScheduler taskScheduler;
  @Override
  public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) 
    scheduledTaskRegistrar.setTaskScheduler(taskScheduler);
