java - quartz xml 配置

Question

我想通过 xml 配置与 Tomcat 服务器一起运行 Quartzjob。但是当我启动 Tomcat 时，我的工作根本没有启动。 任何人都可以帮忙吗？ 这是我的代码:

网络.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app>
<listener>
    <listener-class>
       org.quartz.ee.servlet.QuartzInitializerListener
   </listener-class>
</listener>
</web-app>

我的工作.java

package com.cron;

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


public class MyJob implements Job {

    public void execute(JobExecutionContext context)
     throws JobExecutionException {

      System.out.println("Cron executing ");

    }
}

项目src文件夹下的quartz-config.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>FirstJob</name>
            <group>DummyGroup</group>
            <description>This is FirstJob</description>
            <job-class>com.cron.MyJob</job-class>
        </job>
        <trigger>
            <cron>
                <name>dummyTrigger</name>
                <job-name>FirstJob</job-name>
                <job-group>GroupDummy</job-group>
                <!-- It will run every 2 seconds -->
                <cron-expression>0/2 * * * * ?</cron-expression>
            </cron>
        </trigger>
    </schedule>
</job-scheduling-data>

项目src文件夹下的quartz.properties文件

org.quartz.scheduler.instanceName = MyScheduler
org.quartz.threadPool.threadCount = 3
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
org.quartz.plugin.jobInitializer.class =org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames =quartz-config.xml
org.quartz.plugin.jobInitializer.failOnFileNotFound = true

当我启动 Tomcat 服务器时，它显示在下面的日志

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

我在下面使用的 JAR 文件列表:

quartz-2.2.1.jar
quartz-jobs-2.2.1.jar
slf4j-api-1.7.5.jar
jta-1.1.jar

我在使用 org.quartz.ee.servlet.QuartzInitializerListener 时遇到了问题，我正在使用 servlet 方法。

<!--Quartz-->
<servlet>
    <servlet-name>QuartzInitializer</servlet-name>
    <servlet-class>org.quartz.ee.servlet.QuartzInitializerServlet</servlet-class>
    <init-param>
        <param-name>shutdown-on-unload</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
         <param-name>start-scheduler-on-load</param-name>
         <param-value>true</param-value>
     </init-param>
    <init-param> 
        <param-name>config-file</param-name>
