内容图文

我有调度程序：

@Bean("one")
ThreadPoolTaskScheduler taskScheduler(){
    ThreadPoolTaskScheduler threadPoolTaskScheduler = new ThreadPoolTaskScheduler();
    threadPoolTaskScheduler.setPoolSize(5);
    threadPoolTaskScheduler.setAwaitTerminationSeconds(60);
    threadPoolTaskScheduler.setThreadNamePrefix("Test-");
    return threadPoolTaskScheduler;
}

@Bean("two")
ThreadPoolTaskScheduler taskScheduler2(){
    ThreadPoolTaskScheduler threadPoolTaskScheduler = new ThreadPoolTaskScheduler();
    threadPoolTaskScheduler.setPoolSize(50);
    threadPoolTaskScheduler.setAwaitTerminationSeconds(60);
    threadPoolTaskScheduler.setThreadNamePrefix("Test2-");
    return threadPoolTaskScheduler;
}

和方法：

@Scheduled(fixedRate = 1000L)
public void test() {

第二种方法：

@Scheduled(fixedRate = 1000L)
public void test2() {

如何使用具体的计划程序配置每个@Scheduled方法？

如果我这样实现：

@Slf4j
@Component
public class MyScheduler {

    private final ThreadPoolTaskScheduler taskSchedulerFirst;
    private final ThreadPoolTaskScheduler taskSchedulerSecond;
    private final TestBean testBean;

    public MyScheduler(@Qualifier("first") ThreadPoolTaskScheduler taskSchedulerFirst, @Qualifier("second")ThreadPoolTaskScheduler taskSchedulerSecond, TestBean testBean) {
        this.taskSchedulerFirst = taskSchedulerFirst;
        this.taskSchedulerSecond = taskSchedulerSecond;
        this.testBean = testBean;
    }

    @PostConstruct
    public void test() {
        taskSchedulerFirst.scheduleAtFixedRate(testBean::test, 1000L);
        taskSchedulerSecond.scheduleAtFixedRate(testBean::test2, 1000L);
    }

Bouth调度程序未使用,已使用TaskExecutor：

2018-09-05 11:10:30.812  INFO 10724 --- [TaskExecutor-41] com.example.scheduling.TestBean          : hz
2018-09-05 11:10:31.747  INFO 10724 --- [TaskExecutor-43] com.example.scheduling.TestBean          : hz
2018-09-05 11:10:31.748  INFO 10724 --- [TaskExecutor-46] com.example.scheduling.TestBean          : hz2
2018-09-05 11:10:32.747  INFO 10724 --- [TaskExecutor-45] com.example.scheduling.TestBean          : hz
2018-09-05 11:10:32.748  INFO 10724 --- [TaskExecutor-48] com.example.scheduling.TestBean          : hz2
2018-09-05 11:10:33.747  INFO 10724 --- [TaskExecutor-47] 

但是使用TaskExecutor为什么呢？

解决方法:

TL; DR否

根据Spring scheduling,它们是TaskScheduler抽象的不同实现

> ThreadPoolTask??Scheduler作为实现：

ThreadPoolTaskScheduler, can be used whenever external thread management is not a requirement. Internally, it delegates to a ScheduledExecutorService instance. ThreadPoolTaskScheduler actually implements Spring’s TaskExecutor interface as well, so that a single instance can be used for asynchronous execution as soon as possible as well as scheduled, and potentially recurring, executions.

> @Scheduled作为任务计划的注释支持

The @Scheduled annotation can be added to a method along with trigger metadata.

另请参阅answer for best way to schedule task,投票最多：

The simplest way to schedule tasks in Spring is to create method annotated by @Scheduled in spring managed bean.
