**1、新增pom依赖**

除了按照《[quartz2.3.0系列目录——带您由浅入深全面掌握quartz2.3.0][quartz2.3.0_quartz2.3.0]》添加依赖之外，pom.xml里新增加依赖：

<dependency>
                <groupId>opensymphony</groupId>
                <artifactId>quartz-all</artifactId>
                <version>1.6.3</version>
    </dependency>
    <dependency>
                <groupId>javax.transaction</groupId>
                <artifactId>jta</artifactId>
                <version>1.1</version>
    </dependency>

**2、quartz.properties配置**

#============================================================================
    # Configure Main Scheduler Properties  
    #============================================================================
    
    org.quartz.scheduler.instanceName: TestScheduler
    org.quartz.scheduler.instanceId: AUTO
    
    #============================================================================
    # Configure ThreadPool  
    #============================================================================
    
    org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
    org.quartz.threadPool.threadCount: 3
    org.quartz.threadPool.threadPriority: 5
    
    #============================================================================
    # Configure JobStore  
    #============================================================================
    
    org.quartz.jobStore.misfireThreshold: 60000
    
    org.quartz.jobStore.class: org.quartz.simpl.RAMJobStore
    
    #============================================================================
    # Configure Plugins 
    #============================================================================
    
    org.quartz.plugin.triggHistory.class: org.quartz.plugins.history.LoggingJobHistoryPlugin
    
    org.quartz.plugin.jobInitializer.class: org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
    org.quartz.plugin.jobInitializer.fileNames: quartz_data.xml
    org.quartz.plugin.jobInitializer.failOnFileNotFound: true
    org.quartz.plugin.jobInitializer.scanInterval: 120
    org.quartz.plugin.jobInitializer.wrapInUserTransaction: false

**3、quartz\_data.xml配置**

<?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"

        </pre-processing-commands>
        
        <processing-directives>
            
            <overwrite-existing-data>true</overwrite-existing-data>
            
            <ignore-duplicates>false</ignore-duplicates> 
        </processing-directives>
        
        <schedule>
            <job>

                    <job-name>TestJob2</job-name>

                </cron>
            </trigger>
        </schedule>    
    </job-scheduling-data>

**4、任务类，xml配置文件里指向的job任务类**

package org.quartz.examples.example10;
    
    import java.util.Date;
    import java.util.Set;
    
    import org.quartz.Job;
    import org.quartz.JobExecutionContext;
    import org.quartz.JobExecutionException;
    import org.quartz.JobKey;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    /**
     * job任务类
     */
    public class SimpleJob implements Job {
    
        private static Logger LOG = LoggerFactory.getLogger(SimpleJob.class);
    
        // 必须要有public修饰的无参构造函数
        public SimpleJob() {
        }
    
        // 定时器执行方法
        @SuppressWarnings("unchecked")
        public void execute(JobExecutionContext context) throws JobExecutionException {
            JobKey jobKey = context.getJobDetail().getKey();
            LOG.info("--------- job任务执行: " + jobKey + " executing at " + new Date() + ", fired by: "
                    + context.getTrigger().getKey());
    
            if (context.getMergedJobDataMap().size() > 0) {
                Set<String> keys = context.getMergedJobDataMap().keySet();
                for (String key : keys) {
                    String val = context.getMergedJobDataMap().getString(key);
                    LOG.info("--------- job任务执行。 - jobDataMap entry: " + key + " = " + val);
                }
            }
    
            context.setResult("hello");
        }
    
    }

**5、PlugInExample调度器类**

package org.quartz.examples.example10;
    
    import org.quartz.Scheduler;
    import org.quartz.SchedulerFactory;
    import org.quartz.SchedulerMetaData;
    import org.quartz.impl.StdSchedulerFactory;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    /**
     * 这个示例将生成大量要运行的作业
     */
    public class PlugInExample {
    
        public void run() throws Exception {
            Logger log = LoggerFactory.getLogger(PlugInExample.class);
    
            // 初始化一个调度工厂，并实例化一个调度类
            SchedulerFactory sf = new StdSchedulerFactory();
            Scheduler sched = null;
            try {
                sched = sf.getScheduler();
            } catch (NoClassDefFoundError e) {
                log.error(" 无法加载类——很可能类路径上没有jta.jar。 如果在examples/lib文件夹中没有，请将它添加到这里，以便运行这个示例。", e);
                return;
            }
    
            log.info("----------- 不调度任何作业——依赖于XML定义 ");
    
            sched.start();
            Thread.sleep(300L * 1000L);
    
            sched.shutdown(true);
    
            SchedulerMetaData metaData = sched.getMetaData();
            log.info("Executed " + metaData.getNumberOfJobsExecuted() + " jobs.");
        }
    
        public static void main(String[] args) throws Exception {
    
            PlugInExample example = new PlugInExample();
            example.run();
        }
    
    }
