本文介绍Quartz中如何为任务添加监听器，包括全局注册监听器、为特定任务添加监听器及按组匹配任务的方法。展示了JobCountListener类的具体实现，并提供了一个简单的Job示例。

全局注册,所有Job都会起作用

JobCountListener listener = new JobCountListener();
sched.getListenerManager().addJobListener(listener);

给固定的job添加监听器

JobCountListener listener = new JobCountListener();
Matcher<JobKey> matcher = KeyMatcher.keyEquals(new JobKey("hello3", "group1"));
scheduler.getListenerManager().addJobListener(listener, matcher);

指定一组任务

GroupMatcher<JobKey> matcher = GroupMatcher.jobGroupEquals("group1");
sched.getListenerManager().addJobListener(new MyJobListener(), matcher);

可以根据组的名字匹配开头和结尾或包含

JobCountListener listener = new JobCountListener();
GroupMatcher<JobKey> matcher = GroupMatcher.groupStartsWith("g");
//GroupMatcher<JobKey> matcher = GroupMatcher.groupContains("g");
scheduler.getListenerManager().addJobListener(listener, matcher);

/**

public class JobCountListener implements org.quartz.JobListener {
    private Integer count;

    public String getName() {
        return "job监听";
    }

    public void jobToBeExecuted(JobExecutionContext jobExecutionContext) {
        System.out.println("任务执行前。");
    }

    public void jobExecutionVetoed(JobExecutionContext jobExecutionContext) {
        System.out.println("如果当TriggerListener中的vetoJobExecution方法返回true时,那么执行这个方法。任务被终止");
    }

    public void jobWasExecuted(JobExecutionContext jobExecutionContext, JobExecutionException e) {
        JobDetail jobDetail = jobExecutionContext.getJobDetail();
        System.out.println("Job :" + jobDetail.getKey().getGroup() + "." + jobDetail.getKey().getName());
        Integer current = (Integer) jobExecutionContext.getJobDetail().getJobDataMap().get("count");
        System.out.println("调用次数:" + current);
    }

}

package com.sky.JobSchedule.Job;

import org.quartz.*;
import org.springframework.stereotype.Component;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * @author sky
 */
@Component
@DisallowConcurrentExecution
@PersistJobDataAfterExecution
public class JobCron implements Job {
    String name;

    public JobCron() {
        System.out.println("Hello, Quartz sky! ----------------------");
    }

    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        JobDataMap jobDataMap = jobExecutionContext.getJobDetail().getJobDataMap();
        Integer count = (Integer) jobDataMap.get("count");
        if(count==null){
            count=0;
        }
        count++;
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        System.out.println("Hello, " + count + " sky !" + formatter.format(new Date()));
        jobExecutionContext.getJobDetail().getJobDataMap().put("count", count);
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

重启服务，需要重新添加监听器。
