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 (0–59)
2 Minutes (0–59)
3 Hours (0–23)
4 Day of month (1–31)
5 Month (1–12 or JAN–DEC)
6 Day of week (1–7 or SUN–SAT)
7 Year (1970–2099)
?? ? ? ? ? -->
?
<!-- 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
