.

import org.quartz.jobexecutioncontext; import org.quartz.jobexecutionexception; import org.springframework.scheduling.quartz.quartzjobbean;  import com.spring.server.tasks.sharemetask;  public class sharemejob extends quartzjobbean {     private sharemetask sharemetask;      public void setrunmetask(sharemetask sharemetask) {         this.sharemetask = sharemetask;     }      protected void executeinternal(jobexecutioncontext context)             throws jobexecutionexception {         system.out.println("sharemejob");         sharemetask.printme1();      } } 

.

public class sharemetask {      public void printme2() {          system.err.println("spring 3 + quartz 1.8.6 ~");       }     public void printme1() {          system.err.println("spring job execution");       }  } 

when time reached above class call , method run. if admin want configure cron @ run time how can configure , please tell me code run time configuration , starting scheduler.

i found there methods in shecduler shutdown , start how can use these method @ run time.

we can store cron-expression properties fil configure dynamically, can modify when ever need without touching application code , repacking.

step(1): create file under /path/myfile.properties cronexp.value=* 0/10 * * * ?

step (2): modify spring xml below:

<context:property-placeholder location= "file:/path/myfile.properties" />  <bean id="crontrigger" class="org.springframework.scheduling.quartz.crontriggerbean">         <property name="jobdetail" ref="runmejob" />         <property name="cronexpression" value="${cronexp.value}" /> </bean>
