本文介绍如何在Spring框架中使用Quartz调度框架实现邮件自动发送任务。通过配置Quartz与Spring集成，并创建定时任务及触发器，实现邮件发送功能。
昨天 老大 交下一件任務,在Spring框架下構建一個郵件自動發送模塊,接到此任務的第一個想法是利用Timer, 它小巧功能夠用.
以下是寫的一個測試類.写道
package umt.michael.tsk.test;
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;
/**
* @Title: Test.java
* @Package umt.michael.tsk.test
* @Description: TODO
* @author MichaelYang
* @Email apac.yang@gmail.com
* @date 2011/10/13 下午9:19:01
* @version V1.0
*/
class DateTask extends TimerTask{
@Override
public void run() {
System.out.println("現在時間：" + new Date());
}
}
public class Test {
/**
* @Title: main
* @Description: TODO
* @param args
* @return void
*/
public static void main(String[] args) {
Timer timer = new Timer();
timer.schedule(new DateTask(), 1000,5000);
try{
Thread.sleep(20000);
}catch(Exception e){
System.err.println(e.getMessage());
e.printStackTrace();
}
System.out.println("結束時間是：" + new Date());
timer.cancel();
}
}
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;
/**
* @Title: Test.java
* @Package umt.michael.tsk.test
* @Description: TODO
* @author MichaelYang
* @Email apac.yang@gmail.com
* @date 2011/10/13 下午9:19:01

*/
class DateTask extends TimerTask{
@Override
public void run() {
System.out.println("現在時間：" + new Date());
}
}
public class Test {
/**
* @Title: main
* @Description: TODO
* @param args
* @return void
*/
public static void main(String[] args) {
Timer timer = new Timer();
timer.schedule(new DateTask(), 1000,5000);
try{
Thread.sleep(20000);
}catch(Exception e){
System.err.println(e.getMessage());
e.printStackTrace();
}
System.out.println("結束時間是：" + new Date());
timer.cancel();
}
}
結果為:
現在時間：Thu Oct 13 21:30:12 CST 2011
現在時間：Thu Oct 13 21:30:17 CST 2011
現在時間：Thu Oct 13 21:30:22 CST 2011
現在時間：Thu Oct 13 21:30:27 CST 2011
結束時間是：Thu Oct 13 21:30:31 CST 2011頭兒卻明確要用Quartz 這個任務調度框架.沒辦法,只好拼了,从Quartz官网 http://www.quartz-scheduler.org/ 上下载jar包 现在该版本已经到了2.10，但是在国外一个网站发现貌似 2.1 和Spring3.x 无法兼容，没有验证，为了安全起见，我下载的是穩定版本quartz1.8.5. 相關配置如下.

PROPAGATION_REQUIRED 支持当前事务，如果当前没有事务，就新建一个事务。这是最常见的选择。
PROPAGATION_SUPPORTS 支持当前事务，如果当前没有事务，就以非事务方式执行。
PROPAGATION_MANDATORY 支持当前事务，如果当前没有事务，就抛出异常。
PROPAGATION_REQUIRES_NEW 新建事务，如果当前存在事务，把当前事务挂起。
PROPAGATION_NOT_SUPPORTED 以非事务方式执行操作，如果当前存在事务，就把当前事务挂起。
PROPAGATION_NEVER 以非事务方式执行，如果当前存在事务，则抛出异常。
PROPAGATION_NESTED 如果当前存在事务，则在嵌套事务内执行。如果当前没有事务，则进行与PROPAGATION_REQUIRED类似的操作。
