Question

我的工作没有开始。

我使用2.1.1版本的石英，我的servlet是tomcat。当在triggers_jobs.xml中写入设置时，我必须运行作业。该文件如下所示：

<?xml version='1.0' encoding='utf-8'?>
<quartz>
  <job>
    <job-detail>
      <name>my_job1</name>
      <group>my_group</group>
      <job-class>com.crossreader.webapi.scheduler.ScheduledTasksJob</job-class>
    </job-detail>

      <trigger>
          <cron>
              <name>dailyTrigger</name>
              <group>my_group</group>
              <job-name>my_job1</job-name>
              <job-group>my_group</job-group>
              <!-- trigger that fires every 5 minutes -->
              <cron-expression>0 0/5 * * * _</cron-expression>
          </cron>
      </trigger>
  </job>
</quartz>

我创建了一个如下所示的servlet：

public class SchedulerServlet extends GenericServlet {

  static private final CRLogger LOG = CRLogger.createCRLogger();

  public void init(ServletConfig servletConfig) throws ServletException {
    super.init(servletConfig);

try{
      LOG.info("........ Start SchedulerManager ..............");
      // Grab the Scheduler instance from the Factory
      SchedulerFactory schedulerFactory = new StdSchedulerFactory();
      final Scheduler scheduler = schedulerFactory.getScheduler();

      // start the scheduler
      scheduler.start();

    } catch(SchedulerException e) {
      e.printStackTrace();
    }
  }
}

我创建了一个继承自Job的ScheduledTasksJob类，它看起来像这样：

public class ScheduledTasksJob implements Job{
  public ScheduledTasksJob() {
    LOG.info("........ ScheduledTasksJob Starts - constructor ..............");
  }

  public void execute(JobExecutionContext context) throws JobExecutionException {

    try{
      MyServletClass.runAllJobs();
    } catch(Exception e) {
      e.printStackTrace();
    }
  }
}

这是我的quartz.properties文件：

# This scheduler's name will be "MyQuartzScheduler"
org.quartz.scheduler.instanceName: MyQuartzScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.rmi.export: false
org.quartz.scheduler.rmi.proxy: false

org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
# There are 3 threads in the thread pool, which means that a maximum of 3 jobs can be run simultaneously.
org.quartz.threadPool.threadCount: 3

# All of Quartz's data, such as details of jobs and triggers, is held in memory (rather than in a database).
org.quartz.jobStore.class: org.quartz.simpl.RAMJobStore

org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.fileName = jobs/triggers_jobs.xml
org.quartz.plugin.jobInitializer.overWriteExistingJobs = true
org.quartz.plugin.jobInitializer.failOnFileNotFound = true

这是我在LOG文件中得到的：

为什么类ScheduledTasksJob没有运行？

感谢您的帮助。

作业未使用triggers_jobs.xml配置文件运行
