以编程方式创建Spring Framework任务？ [英] Creating Spring Framework task programmatically?

问题描述

我需要在我的应用中动态创建任务。我怎样才能做到这一点？我可以使用 @autowired 注释来获取调度程序，但调度程序需要 Runnable 对象。我需要提供Spring对象，以便我的任务也可以使用 @autowired 注释。

I need to create task on the fly in my app. How can I do that? I can get scheduler with @autowired annotation, but scheduler takes Runnable objects. I need to give Spring objects, so that my tasks can use @autowired annotation too.

@Autowired private TaskScheduler taskScheduler;

推荐答案

您只需要将目标对象包装在 Runnable ，并提交：

You just need to wrap your target object in a Runnable, and submit that:

private Target target;  // this is a Spring bean of some kind
@Autowired private TaskScheduler taskScheduler;

public void scheduleSomething() {
    Runnable task = new Runnable() {
       public void run() {
          target.doTheWork();
       }
    };
    taskScheduler.scheduleWithFixedDelay(task, delay);
}
