Spring Timer Simple to use

Move from spring timed task

Spring Scheduled task is very powerful, the last simple application, to share the next, I hope we have a lot of communication!

This is a timed print time console, which is a simple scheduled task!

Please look at the program's Running source code:

First create a new class: Tellingthetimejob This class is inherited from Spring rewrite executeinternal this method.

package jobs;    import org.quartz.jobexecutioncontext;  import  org.quartz.jobexecutionexception;  import org.springframework.scheduling.quartz.quartzjobbean;   import service. itellingthetimeservice;      /**  *  @ProjectName: Chime demo      *  @ClassName:tellingthetimejob     *  @Description:      *  @author:sheep  *  @date:2012-4-19  pm 03:58:11      *  @Modifier:   *  @Modify  date:    *   @Modify  Note:     *  @version   */  public  class tellingthetimejob extends quartzjobbean {             private itellingthetimeservice tellingthetimeservice = null;         @Override       protected  void executeinternal (jobexecutioncontext arg0)  throws jobexecutionexception {           //Call Chime Method            this.tellingthetimeservice.tellingthetime ();      }         public itellingthetimeservice gettellingthetimeservice ()  {          return tellingTheTimeService;       }        public void  Settellingthetimeservice (               Itellingthetimeservice tellingthetimeservice)  {           this.tellingthetimeservice = tellingthetimeservice;      }  }   Establish an interface Itellingthetimeservice, function in order to implement timed call [java] view plaincopypackage service;       /**  *  @ProjectName: Chime demo   * @ classname:itellingthetimeservice     *  @Description:      *  @author:sheep  *  @date:2012-4-19  pm 03:59:37     *   @Modifier:   *  @Modify  Date:    *  @Modify  note:      *  @version   */  public interface  itellingthetimeservice {            /**       *  @Title:  tellingthetime       *   @Description:  Current Time        &Nbsp;    *  @throws       */       void tellingthetime ();   }

Establish an interface Itellingthetimeservice function in order to implement a timed call

package service;      /**  *  @ProjectName: Chime demo    *  @ClassName:itellingthetimeservice     *  @Description:      *  @author:sheep  *  @date:2012-4-19  pm 03:59:37      *  @Modifier:   *  @Modify  Date:    *  @Modify  Note:     *  @version   */  public interface  itellingthetimeservice {            /**       *  @Title:  tellingthetime       *   @Description:  Current Time             * @ Throws      */      void tellingthetime ();   }

This allows you to implement spring timed tasks, the referenced jar is: Commons-collections.jar,commons-logging-1.0.4.jar, Log4j-1.2.15.jar,quartz-1.6.1-rc1.jar and Spring.jar (2.5).

Summarize

Main steps:

First step: Create a new class and integrate Quartzjobbean and override the Executeinternal method ()

Step Two: Configure the Applicationcontent.xml file

(1) <!--  Configure a job -->      <bean id= "Tellthetimejob"   class= "Org.springframework.scheduling.quartz.JobDetailBean" >           <property name= "Jobclass"  value= "jobs. Tellingthetimejob "/>          <property name=" Jobdataasmap ">              <map >                   <entry key= "Tellingthetimeservice"  value-ref= "Tellingthetimeservice" ></entry>               </map>           </property>      </bean >   (2)  <!--  Complex trigger  -->  &nbsP;   <bean id= "Complextellthetimetrigger"  class= " Org.springframework.scheduling.quartz.CronTriggerBean ">           <property name= "Jobdetail" >               <ref bean= "Tellthetimejob"/>           </property>          <property  name= "Cronexpression" >               <!--  Here is the focus, you can customize the expression to implement timed triggering. The following meanings are triggered once per minute  -->               <value>0 0/1 * * * ?</value>           </property>      </bean>   (3) <!--  spring Trigger Factory  --&Gt;      <bean class= " Org.springframework.scheduling.quartz.SchedulerFactoryBean ">           <property name= "Triggers" >               <list>                   <ref bean= "Complextellthetimetrigger"/>                   <!--&nbsp, ..... You can continue to add additional triggers below  -->               </list>          </property>       </bean>

Step Three: Configure the spring context in XML

<!--Configure the spring XML context path--<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext*.xml</param-value> </context-param> <l Istener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> & Lt;/listener>
