如何使用 java Spring MVC 安排邮件

Question

I have created an application in which I want to add schedule mail feature. I have created application using Java spring MVC. Is there a way to schedule mail using Java spring. I want to send mail 24 hours before the event is occured.

Answer 1

You can create a job with using the @Scheduled annotation. Every job's tick (for example, every day at 6 AM) you can check which messages are ready to be sent and then send them. Don't forget also to add the @EnableScheduling annotation in your config.

@Component
public class MailSenderJob {

   @Scheduled(cron = "0 0 6 * * ?")
   public void execute() {
      ...
      send(messages);
    }
}

For more information about scheduling check the Scheduling Tasks guide.
