Question

我提到了Quartz properties does not trigger Quartz Job上发现的上一个问题，并从中大量借用（作为Quartz和所有人的新手），但我的工作似乎没有解雇。

我的quartz.properties：

org.quartz.scheduler.instanceName = MyScheduler
org.quartz.threadPool.threadCount = 3
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

#===================================================
# Configure the Job Initialization Plugin
#===================================================

org.quartz.plugin.triggerHistory.class: org.quartz.plugins.history.LoggingTriggerHistoryPlugin
org.quartz.plugin.jobInitializer.class: org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames: quartz-jobs.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound: true
org.quartz.plugin.jobInitializer.scanInterval: 10
org.quartz.plugin.jobInitializer.wrapInUserTransaction: false

我的quartz-job.xml：

<?xml version='1.0' encoding='utf-8'?>
<job-scheduling-data xmlns="http://www.quartz-scheduler.org/xml/JobSchedulingData"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.quartz-scheduler.org/xml/JobSchedulingData http://www.quartz-scheduler.org/xml/job_scheduling_data_1_8.xsd"
version="1.8">

    <schedule>
        <job>
            <name>myjob</name>
            <group>MYJOBGROUP</group>
            <description>Job to Test</description>
            <job-class>com.mpm.epick.enotify.EmailNotifier</job-class>
        </job>
        <trigger>
            <cron>
                <name>my-trigger</name>
                <group>MYTRIGGER_GROUP</group>
                <job-name>myjob</job-name>
                <job-group>MYJOBGROUP</job-group>
                <cron-expression>* * * * * ?</cron-expression>
            </cron>
        </trigger>
    </schedule>

</job-scheduling-data>

我在web.xml中添加的部分：

我希望运行的类文件，`EmailNotifier'（现在它只是一个存根实现）：

package com.mpm.epick.enotify;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class EmailNotifier implements Job {

    public EmailNotifier() {}

    public void execute(JobExecutionContext context) throws JobExecutionException {
        System.out.println("Cron executing ");
    }

}

所以我观察到我的调度程序可以正常启动/停止，如以下调试行所示：

INFO: QuartzInitializer: Scheduler has been started...
INFO: QuartzInitializer: Quartz Scheduler successful shutdown.

但是在我的控制台上我根本看不到调试行。我尝试了日志文件，但它也没有。

我错过了解雇工作的事情吗？

我想知道这是否是因为你的cron表达式很奇怪。我不确定“* * * * *？”的意图是什么表达式，但是如果你想让它每秒开一次你应该使用“0/1 * * * *？”。有关构建cron表达式的更多信息，请参阅http://quartz-scheduler.org/documentation/quartz-2.x/tutorials/tutorial-lesson-06。
