Question

我正在尝试使用Spring计划任务。这是我的代码：

@Service
public class MyWork implements Runnable {
    @Override
    public void run() {
        workToDo();
    }


    private void workToDo()  { /*do it*/}
}

@Service
public class MySchedulerInvoker {
    @Autowired
    private TaskScheduler scheduler;

    @Async
    public void executeTask() {
    scheduler.schedule(new MyWork(), new CronTrigger(
            "* 15 9-17 * * MON-FRI"));
}

当我跑步时，我收到以下错误：

ava.lang.ExceptionInInitializerError

缺少什么？

Answer 1

在与TaskScheduler相同的上下文中，没有MySchedulerInvoker bean可用。您需要为某人显示一些配置以指出原因。

Spring中的TaskScheduler的NoSuchBeanDefinition
