Quarts(定时)在Spring中应用实例
最近项目要实现一个定时批量提交数据的功能，采用Spring的Quarts的技术来实现。
以下是使用实例：
首先：
编写自己的Service类和方法，这些省略咯。。主要讲怎么使用Quarts：
package com.wonders.hs.registration.healthevent.front.quartz;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Logger;
import javax.xml.datatype.DatatypeConfigurationException;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
import com.wonders.hs.registration.healthevent.front.service.HealthEventFrontService;
public class QuartzJobFront extends QuartzJobBean {
private HealthEventFrontService healthEventFrontService;
private Logger log = Logger.getAnonymousLogger();
@Override
protected void executeInternal(JobExecutionContext arg0)
throws JobExecutionException {
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
log.info("我是用quartz定时器打印出来的"+format.format(new Date()));
try {
long start = System.nanoTime();
//批量注册前置表数据
healthEventFrontService.registHealthEventFront();
long end = System.nanoTime();
log.info("总耗时:" + (end-start)/1000000000.0000);
} catch (DatatypeConfigurationException e) {
e.printStackTrace();
}
}
public void setHealthEventFrontService(
HealthEventFrontService healthEventFrontService) {
this.healthEventFrontService = healthEventFrontService;
}
}
在spring的配置文件中配置相关的Quarts信息：

其中<!-- Quartz Job 定时操作 开始 -->之后的代码是配置Quartz Job 定时操作的，嘿嘿。。
这样万事俱备，搞定啦。。。
另外，定时的时间设置貌似有点复杂，这里一并把他贴出来。。
附表 CronTrigger Expression( 来自http://quartz.sourceforge.net/javadoc/org/quartz/CronTrigger.html) Expression Meaning "0 0 12 * * ?" Fire at 12pm (noon) every day "0 15 10 ? * *" Fire at 10:15am every day "0 15 10 * * ?" Fire at 10:15am every day "0 15 10 * * ? *" Fire at 10:15am every day "0 15 10 * * ? 2005" Fire at 10:15am every day during the year 2005 "0 * 14 * * ?" Fire every minute starting at 2pm and ending at 2:59pm, every day "0 0/5 14 * * ?" Fire every 5 minutes starting at 2pm and ending at 2:55pm, every day "0 0/5 14,18 * * ?" Fire every 5 minutes starting at 2pm and ending at 2:55pm, AND fire every 5 minutes starting at 6pm and ending at 6:55pm, every day "0 0-5 14 * * ?" Fire every minute starting at 2pm and ending at 2:05pm, every day "0 10,44 14 ? 3 WED" Fire at 2:10pm and at 2:44pm every Wednesday in the month of March. "0 15 10 ? * MON-FRI" Fire at 10:15am every Monday, Tuesday, Wednesday, Thursday and Friday "0 15 10 15 * ?" Fire at 10:15am on the 15th day of every month "0 15 10 L * ?" Fire at 10:15am on the last day of every month "0 15 10 ? * 6L" Fire at 10:15am on the last Friday of every month "0 15 10 ? * 6L" Fire at 10:15am on the last Friday of every month "0 15 10 ? * 6L 2002-2005" Fire at 10:15am on every last friday of every month during the years 2002, 2003, 2004 and 2005 "0 15 10 ? * 6#3" Fire at 10:15am on the third Friday of every month
顺便上传quarts的包和一个相关的spring的包。。。。
