我需要对AEM Scheduler进行任何其他更改吗？

我正在尝试为我的项目需求实现简单的调度程序，我的项目正在使用pixels。到目前为止，我浏览了Adobe网站并尝试实现所提供的示例，但是没有一个示例更新我的Adobe AEM文件。

error.log

因此，根据this，它应该可以工作

package sling.docu.examples; import com.majesco.logger.service.impl.Logger; import org.apache.felix.scr.annotations.Component; import org.apache.felix.scr.annotations.Service; import org.apache.felix.scr.annotations.Property; import com.majesco.dcf.common.util.CommonConstants; @Component @Service(value = Runnable.class) @Property( name = "scheduler.period", longValue = 10) public class ScheduledPeriodicJob implements Runnable { Logger logger = new Logger().getInstance(CommonConstants.COMMONSERVICE_MODULE_ID); public void run() { logger.debug("#########################################"); logger.debug("*****************************************"); logger.debug("*****************************************"); logger.debug("*****************************************"); logger.debug("******** ScheduledPeriodicJob ***********"); logger.debug("*****************************************"); logger.debug("*****************************************"); logger.debug("*****************************************"); logger.debug("#########################################"); } } 的依赖性

pom.xml

是否需要进行其他任何更改才能使调度程序正常工作？请提出缺失的内容。

2 个答案:

答案 0 :(得分：1)

您未设置immediate = true。通过bundle-start自动启动/激活组件/服务。否则，仅当另一个（已启动）服务请求此服务（或具有依赖项）时，才启动该服务。

在OSGi中，所有服务都是延迟启动的，一旦没有人需要它们便立即停止。我同意，如果调度程序服务将自动启动它将触发的所有服务，则可以进行改进。就是这样。

这是一个有效的示例。 

@Component(immediate = true, metatype = true)
@Service({ Runnable.class, AnotherServiceInterface.class})
@Properties({
   // run every 5 seconds
   @Property(name = "scheduler.period", longValue = 5),
   // no concurrent execution
   @Property(name = "scheduler.concurrent", propertyPrivate = true, boolValue = false)
})

以下解决方案按要求工作，这里处理了三种情况

  • 使用addJob()：每分钟执行一次工作
  • 使用addPeriodicJob()：每3分钟执行一次作业

  • with fireJobAt()：在特定日期（部署日期+ 30秒的延迟）执行作业
