Spring scheduled annotation

 Spring has nice feature called scheduler. Just simply create class and annotate method with @Scheduled(...) annotation and it's all. You have scheduled task, that wil be executed based on your time expression. Example:

package com.test.jobs;

@Component("testTask")
public class TestTask {

       //Fire at 8:30am every day
        @Scheduled(cron="0 30 8 ? * *")
        public void doSmth(){
          //do it...
        }
}

Of course spring config:
