定時器使用場景（固定時間程序自動執行部分功能）。
使用步驟
一：配置初始化bean
<bean class="com.sinotrans.visualizationplatform.InstantiationTracingBeanPostProcessor" />二：代碼實現
1、QuartzTest,.java
package com.sinotrans.visualizationplatform.test;
import java.text.SimpleDateFormat;
import java.util.Date;
public class QuartzTest {
/** *//**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
SimpleDateFormat DateFormat = new SimpleDateFormat("yyyyMMddHHmmss");
Date d = new Date();
String returnstr = DateFormat.format(d);
TestJob job = new TestJob();
String job_name ="11";
try {
System.out.println(returnstr+ "【系統啓動】");
QuartzManager.addJob(job_name,job,"0/2 * * * * ?"); //每2秒鐘執行一次
// QuartzManager.addJob("",null,"0/2 * * * * ?"); //每2秒鐘執行一次
// Thread.sleep(10000);
// System.out.println("【修改時間】");
// QuartzManager.modifyJobTime(job_name,"0/10 * * * * ?");
// Thread.sleep(20000);
// System.out.println("【移除定時】");
// QuartzManager.removeJob(job_name);
// Thread.sleep(10000);
//
// System.out.println("/n【添加定時任務】");
// QuartzManager.addJob(job_name,job,"0/5 * * * * ?");
} catch (Exception e) {
e.printStackTrace();
}
}
}

3、要執行的任務
package com.sinotrans.visualizationplatform.test;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class TestJob implements Job {
SimpleDateFormat DateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date d = new Date();
String returnstr = DateFormat.format(d);
public void execute(JobExecutionContext arg0) throws JobExecutionException {
// TODO Auto-generated method stub
System.out.println(returnstr+"★★★★★★★★★★★");
}
}
