我正在自学Spring，目前正在执行计划任务，以下代码不会触发计划任务。
我认为这与我设置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，所以请原谅荒谬的while循环。
Application.java：
package hello;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
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();
}
}

要清楚，睡眠2.5秒并打印“循环”就可以让应用程序继续运行，以查看计划任务是否会触发。
我正在寻找的是计划任务，它会打印出来的时间。它没有。
提前感谢您提供的任何帮助。

你没有ScheduledTasks豆。使用@Component（或其任何专业化）为您的课程添加注释，或在@Bean课程中为其声明@Configuration方法。
@EnableScheduling属于@Configuration类，而不属于具有预定行为的类。您可以将其从ScheduledTasks删除。
