Spring Comes with timer

Http://www.cnblogs.com/pengmengnan/p/6714203.html

Note Mode Spring Timer
1, first configure our Spring.xml
xmlns add the following content,
xmlns:task= "http://www.springframework.org/ SCHEMA/TASK&NBSP
 
and xsi:schemalocation Add the following,
1. Http://www.springframework.org/schema/task  
2. 
http://www.springframework.org/schema/task/spring- 
task-3.1.xsd 
2, Task Task Scan note
<task:annotation-driven/>
3, the configuration scan location is:
<context:annotation-config/> 
<bean 
class= "ORG.SPRINGFRAMEWORK.BEANS.FACTORY.ANNOTATION.AU&NBSP;
Towiredannotationbeanpostprocessor "/>&NBSP;
<context:component-scan base- 
package=" Com.jk.spring "/>&NBSP;
4, write an interface
public interface Springhorodateuri {
public void myTest ();  
}
5, interface implementation class
//import 
org.springframework.scheduling.annotation.Scheduled;
Import org.springframework.stereotype.Component;

@Component//import
Org.springframework.stereotype.Component;
public class Springhorodateur implements
springhorodateuri{

@Scheduled (cron= "0/5 * * * *?) ")//every 5 seconds to perform a
Times
@Override
public void MyTest () {
System.out.println (">>>>>>>>>>>>> entry test
Try it! ");
}

}

Complete!
A few things to note:
1, spring @scheduled annotations need to write on the implementation,
2, the Timer task method can not have a return value (if there is a return value, spring initial
Will tell you that there is a mistake, you need to set a Proxytargetclass
A value of true, specific to Baidu Google bar)
3, the implementation of the class to have component annotations @component
