SpringBoot之解决多个定时任务阻塞的问题

protected void scheduleTasks() {
  if (this.taskScheduler == null) {
   this.localExecutor = Executors.newSingleThreadScheduledExecutor();
   this.taskScheduler = new ConcurrentTaskScheduler(this.localExecutor);
  }
}

@Configuration
public class ScheduleConfig implements SchedulingConfigurer {
    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        //设定一个长度10的定时任务线程池
        taskRegistrar.setScheduler(Executors.newScheduledThreadPool(10));
    }
}

spring.task.scheduling.pool.size=10

@Bean
public ThreadPoolTaskExecutor taskExecutor() {
    ThreadPoolTaskExecutor poolTaskExecutor = new ThreadPoolTaskExecutor();
    poolTaskExecutor.setCorePoolSize(4);
    poolTaskExecutor.setMaxPoolSize(6);
    // 设置线程活跃时间（秒）
    poolTaskExecutor.setKeepAliveSeconds(120);
    // 设置队列容量
    poolTaskExecutor.setQueueCapacity(40);
    poolTaskExecutor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
    // 等待所有任务结束后再关闭线程池
    poolTaskExecutor.setWaitForTasksToCompleteOnShutdown(true);
    return poolTaskExecutor;
}

@Async
@Scheduled(cron = "0/2 * * * * ? ")
public void test2() {
    System.out.println("..................执行test2.................");
}
