最近公司要做个接口定时任务，本来考虑使用java API中的Timer + TimerTask，其实这个类还是蛮强大的，对于执行时间和执行间隔，调控起来也比较容易。
timer.schedule(new MyTask(),calendar.getTime(), 24*60*60*1000)
也就准备用着个了，写个listener监听器，启动服务器一直报null错误。因为服务器启动的时候会去执行监听器，而监听器会执行到这个schedule方法，也就是
说会去执行new MyTask()，此时不知道是Spring未加载的原因还是什么？MyTask()中声明的service方法一直为空，弄了好长时间也没解决，放弃。
第二方案准备使用spring自带的监听器
<bean id="interfaceInvokeAutoTestTask" class="*.InterfaceInvokeAutoTestTask" > </bean> <bean id="scheduledTask" class="org.springframework.scheduling.timer.ScheduledTimerTask"> <property name="timerTask"> <ref bean="interfaceInvokeAutoTestTask"/> </property> <!-- 任务执行周期 关于一些任务的参数请参考JDK doc文档和Spring相关文档--> <property name="period"> <value>10000000</value> </property> <!-- 延时10s 执行任务 --> <property name="delay"> <value>5000000</value> </property> </bean> <!-- 启动定时器 --> <bean id="timerBean" class="org.springframework.scheduling.timer.TimerFactoryBean"> <property name="scheduledTimerTasks"> <list> <ref bean="scheduledTask" /> </list> </property> </bean>
问题1：执行时间控制起来会麻烦点；
问题2：多次执行后执行时间会有延迟，这方面参考其他文档，
ScheduledTimerTask //执行任务单线程
问题3：spring本身已经抛弃
于是考虑使用quarts，下载，导jar就不说了。
直接开始说例子1吧
public class HelloJob implements Job {
private static Logger _log = LoggerFactory.getLogger(HelloJob.class);
/**

public void execute(JobExecutionContext context)
throws JobExecutionException {

关于简单的定时任务上面的例一已经说明
下面看例2，从任务开始时间，执行次数，执行间隔来控制任务
JobDetail job = newJob(SimpleJob.class)
.withIdentity("job1", "group1")
.build();
SimpleTrigger trigger = (SimpleTrigger) newTrigger()
.withIdentity("trigger1", "group1")
.startAt(startTime)
.build(); //默认执行一次，也就无间隔
Date ft = sched.scheduleJob(job, trigger);
log.info(job.getKey() +
" will run at: " + ft +
" and repeat: " + trigger.getRepeatCount() +
" times, every " + trigger.getRepeatInterval() / 1000 + " seconds");
//group1.job1 will run at: Mon Dec 17 10:05:30 CST 2012 and repeat: 0 times, every 0 seconds
// job3 will run 11 times (run once and repeat 10 more times)
// job3 will repeat every 10 seconds
job = newJob(SimpleJob.class)
.withIdentity("job3", "group1")
.build();
trigger = newTrigger()
.withIdentity("trigger3", "group1")
.startAt(startTime)
.withSchedule(simpleSchedule()
.withIntervalInSeconds(10)
.withRepeatCount(10))
.build();
//group1.job3 will run at: Mon Dec 17 10:05:30 CST 2012 and repeat: 10 times, every 10 seconds
// the same job (job3) will be scheduled by a another trigger
// this time will only repeat twice at a 70 second interval
trigger = newTrigger()
.withIdentity("trigger3", "group2")
.startAt(startTime)
.withSchedule(simpleSchedule()
.withIntervalInSeconds(10)
.withRepeatCount(2))
.forJob(job)
.build();
//group1.job3 will [also] run at: Mon Dec 17 10:24:30 CST 2012 and repeat: 2 times, every 10 seconds
// job4 will run 6 times (run once and repeat 5 more times)
// job4 will repeat every 10 seconds
job = newJob(SimpleJob.class)
.withIdentity("job4", "group1")
.build();
trigger = newTrigger()
.withIdentity("trigger4", "group1")
.startAt(startTime)
.withSchedule(simpleSchedule()
.withIntervalInSeconds(10)
.withRepeatCount(5))
.build();
//group1.job4 will run at: Mon Dec 17 10:24:30 CST 2012 and repeat: 5 times, every 10 seconds
// job5 will run once, five minutes in the future
job = newJob(SimpleJob.class)
.withIdentity("job5", "group1")
.build();
trigger = (SimpleTrigger) newTrigger()
.withIdentity("trigger5", "group1")
.startAt(futureDate(5, IntervalUnit.MINUTE))
.build();
//group1.job5 will run at: Mon Dec 17 10:29:18 CST 2012 and repeat: 0 times, every 0 seconds
// job6 will run indefinitely, every 40 seconds
job = newJob(SimpleJob.class)
.withIdentity("job6", "group1")
.build();
trigger = newTrigger()
.withIdentity("trigger6", "group1")
.startAt(startTime)
.withSchedule(simpleSchedule()
.withIntervalInSeconds(40)
.repeatForever())
.build();
//group1.job6 will run at: Mon Dec 17 10:24:30 CST 2012 and repeat: -1 times, every 40 seconds
// jobs can also be scheduled after start() has been called...
// job7 will repeat 20 times, repeat every five minutes
job = newJob(SimpleJob.class)
.withIdentity("job7", "group1")
.build();
trigger = newTrigger()
.withIdentity("trigger7", "group1")
.startAt(startTime)
.withSchedule(simpleSchedule()
.withIntervalInMinutes(5) //5* 60000
.withRepeatCount(20))
.build();
//group1.job7 will run at: Mon Dec 17 10:24:30 CST 2012 and repeat: 20 times, every 300 seconds
// jobs can be fired directly... (rather than waiting for a trigger)
job = newJob(SimpleJob.class)
.withIdentity("job8", "group1")
.storeDurably()
.build();
sched.addJob(job, true);
log.info("'Manually' triggering job8...");
sched.triggerJob(jobKey("job8", "group1"));
//手动触发一个任务
重新触发
// jobs can be re-scheduled...
// job 7 will run immediately and repeat 10 times for every second
log.info("------- Rescheduling... --------------------");
trigger = newTrigger()
.withIdentity("trigger7", "group1")
.startAt(startTime)
.withSchedule(simpleSchedule()
.withIntervalInMinutes(5)
.withRepeatCount(20))
.build();
显示执行信息
// display some stats about the schedule that just ran
SchedulerMetaData metaData = sched.getMetaData();
log.info("Executed " + metaData.getNumberOfJobsExecuted() + " jobs.");
//Executed 35 jobs.
接下来看例子3，执行条件表达式
// job 1 will run every 20 seconds
JobDetail job = newJob(SimpleJob.class)
.withIdentity("job1", "group1")
.build();
CronTrigger trigger = newTrigger()
.withIdentity("trigger1", "group1")
.withSchedule(cronSchedule("0/20 * * * * ?")) // 20秒执行一次 0,20,40,0---
.build();
Date ft = sched.scheduleJob(job, trigger);
log.info(job.getKey() + " has been scheduled to run at: " + ft
+ " and repeat based on expression: "
+ trigger.getCronExpression());
//group1.job1 has been scheduled to run at: Mon Dec 17 13:11:40 CST 2012 and repeat based on expression: 0/20 * * * * ?
// job 2 will run every other minute (at 15 seconds past the minute)
job = newJob(SimpleJob.class)
.withIdentity("job2", "group1")
.build();
trigger = newTrigger()
.withIdentity("trigger2", "group1")
.withSchedule(cronSchedule("15 0/2 * * * ?")) //没隔一分钟，15秒时执行一次
.build();
下面不贴代码了，将例子中所写的表达式做个说明
// job 3 will run every other minute but only between 8am and 5pm "0 0/2 8-17 * * ?" // job 4 will run every three minutes but only between 5pm and 11pm 0 0/3 17-23 * * ? // job 5 will run at 10am on the 1st and 15th days of the month 0 0 10am 1,15 * ? // job 6 will run every 30 seconds but only on Weekdays (Monday through Friday) 0,30 * * ? * MON-FRI // job 7 will run every 30 seconds but only on Weekends (Saturday and Sunday) 0,30 * * ? * SAT,SUN

| Quartz Cron 表达式支持到七个域 | |||
| 名称 | 是否必须 | 允许值 | 特殊字符 |
| 秒 | 是 | 0-59 | , - * / |

| 年 | 否 | 空 或 1970-2099 | , - * / |
可以看到基本结构是 秒_分_小时_日_月_[周]_[年] 后面的周和年是可选的
其次，通配符，主要的有星号(*)；问号(?)；减号(-)；逗号(,)；斜杠(/)；L字母；W字母；井号(#).
- 星号：表示任意时刻
- 问号：只能在日或周字段上使用，http://blog.csdn.net/chh_jiang/article/details/4603529 这里有比较清晰的解释，简单的理解就是日期和星期是有冲突的，指定其中一个的话，另外一个是没办法指定的，比如每个月12号和每个星期二，这两个是"互斥"的，不能用日期和周来指定所有“每个是星期二的12号”这个时间。
- 减号：范围，如 1-5秒
- 逗号：列表，如 1,5,10 秒
- 斜杠：等步长序列，如3/13秒 表示 3,16,29,42,55,3,16...
- L：仅在日和周上支持，表示允许的最后一个值，注意不要让范围和列表与L连用
- W：工作日
- 井号：为给定月份指定具体的工作日实例。把“MON#2”放在周内日期字段中，表示把任务安排在当月的第二个星期一。(引用)
例4主要讲解下job中的JobDataMap
// pass initialization parameters into the job
job1.getJobDataMap().put(ColorJob.FAVORITE_COLOR, "Green");
job1.getJobDataMap().put(ColorJob.EXECUTION_COUNT, 1);
public void execute(JobExecutionContext context)
throws JobExecutionException {
// This job simply prints out its job name and the
// date and time that it is running
JobKey jobKey = context.getJobDetail().getKey();
// Grab and print passed parameters
JobDataMap data = context.getJobDetail().getJobDataMap();
String favoriteColor = data.getString(FAVORITE_COLOR);
int count = data.getInt(EXECUTION_COUNT);
}

Map<String, Object> wrappedMap = jobDataMap.getWrappedMap();
Collection<Object> values = wrappedMap.values();
String templateId = null;
for (Object object : values) {
templateId = (String)object; //获得当前任务的ID号
}
try {
/* 设置为 一个触发器触发一个任务
* 获得当前触发器的下一次执行时间，如果为null的话
* 则表示当前的任务已经执行完
*/
Date nextFireTime = context.getScheduler().getTrigger(new TriggerKey(templateId,templateId)).getNextFireTime();
//当任务的下一次执行时间为null的时候，表示任务已经结束了，此时将任务的运行状态设置为停止 (0)
if(nextFireTime == null){
SysInterfaceTimerTask selectByTemplateID = sysInterfaceTimerTaskMapper.selectByTemplateID(templateId);
selectByTemplateID.setIsRun("0");
sysInterfaceTimerTaskMapper.updateByTempId(selectByTemplateID);
}
} catch (SchedulerException e) {
e.printStackTrace();
}
System.out.println("任务执行完成了");
}
}
至此，计划任务基本完成。
