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

           -->

          <property name="cronExpression" value="30/5 * * * * ?" />

class="org.springframework.scheduling.quartz.SchedulerFactoryBean"有属性配置：
<property name="autoStartup" value="false" />。


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();

有点奇怪， quartz用到了javax.transaction，如果不加如下的dependency：

<dependency>
        <groupId>javax.transaction</groupId>
        <artifactId>jta</artifactId>
        <version>1.1</version>
        <scope>runtime</scope>
</dependency>

就报下面的异常：
