Spring下配置job
没什么可说的, 今天把以前配置的一个job重新整理了下,用maven管理了。?
?
?
应该说用Maven的特性更多一些:打成的jar是可运行的, 打成的jar包里包括了运行所依赖的jar。
?
?
执行“mvn package”后, 再运行“java -jar .\target\rmn190Proj-jar-with-dependencies.jar”命令。
?
如下输出:
?
main started. and current second is: 1
job executed.current second is: 30
job executed.current second is: 35
job executed.current second is: 40
job executed.current second is: 45
job executed.current second is: 50
job executed.current second is: 55
?

============
关于job运行时间点,applicationContext.xml文件中有如下说明
?
??<!--?
?? ? ? ? ?1 Seconds (059)
2 Minutes (059)
3 Hours (023)
4 Day of month (131)
5 Month (112 or JANDEC)
6 Day of week (17 or SUNSAT)
7 Year (19702099)
?? ? ? ? ? -->
?
<!-- 每隔5秒跑一次,30表示首次执行时等30秒, ?
?? ? ? ? ? 实验所得数据如下:
main started. and current second is: 1
job executed.current second is: 30
job executed.current second is: 35
job executed.current second is: 40
job executed.current second is: 45
job executed.current second is: 50
job executed.current second is: 55
job executed.current second is: 30
job executed.current second is: 35
job executed.current second is: 40
?? ? ? ? ? -->
?? ? ? ? ?<property name="cronExpression" value="30/5 * * * * ?" />
?

这样设置成false后,就可以通过如下API来有判断地启动了:
StdScheduler jobStarter =
(StdScheduler)appContext.getBean("jobStarter");
jobStarter.start();
