春季计划任务未触发 [英] Spring scheduled tasks not firing
本文介绍了春季计划任务未触发的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在自学Spring，目前在计划任务上，下面的代码没有触发计划任务.
我相信这与我设置 Spring 上下文的方式有关，但这只是一个猜测 - 我正在尝试学习 Spring，所以请原谅可笑的 while 循环.

我正在寻找的是打印触发时间的计划任务.没有.
预先感谢您提供的任何帮助.
解决方案
您没有 ScheduledTasks bean.使用 @Component(或其任何特化)注释您的类，或在您的 @Configuration 类中为其声明一个 @Bean 方法.<小时>
@EnableScheduling 属于 @Configuration 类，而不属于具有预定行为的类.您可以从 ScheduledTasks 中删除它.
I'm teaching myself Spring, currently on scheduled tasks, and the following code does not fire the scheduled task.
I believe it has something to do with the way I'm setting up the Spring context but that's only a guess - I'm trying to learn Spring so please excuse the ridiculous while loop.
Application.java:
package hello;

public class Application {
public static void main(String[] args) throws Exception {
AnnotationConfigApplicationContext rootContext =
new AnnotationConfigApplicationContext();
rootContext.register(RootContextConfiguration.class);
rootContext.refresh();
while(rootContext != null) {
try {
Thread.sleep(2500);
} catch(InterruptedException ex) {
Thread.currentThread().interrupt();
}
System.out.println("Loop\n");
}
rootContext.close();
}
}

To be clear, the sleeping for 2.5s and print "Loop" is just there to keep the application running to see if the scheduled tasks fire.
What I'm looking for is the scheduled task which prints the time to fire. It does not.
Thanks in advance for any help you can offer.
解决方案
You don't have a ScheduledTasks bean. Annotate your class with @Component (or any of its specializations) or declare a @Bean method for it in your @Configuration class.
@EnableScheduling belongs on a @Configuration class, not on the class which has the scheduled behavior. You can remove it from ScheduledTasks.
