具体代码见： https://gitee.com/hongdu_dudua1/spring_quartz_mq/tree/master/batch_quartz

spring batch 主要是任务批处理的框架， 对每个任务分成三个步骤： 

1： reader

2： processor

3： writer

spring对quartz的集成主要在 spring-context-support这个包中

quartz的任务调度集成要点：

1： QuartzJobBean  

  这个是集成Quartz的job类： 使用springbatch进行集成的时候，在这个类的方法中：

protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
   //todo spring batch的job执行
}

上面这个部分涉及到很重要的一个类： 

SchedulerContext：是调度器 Scheduler的一个属性， 可以存储spring管理的bean， 因此我们在配置的时候可以将springbatch的任务启动器及任务名字还有job定位器JobLocator存放在这个调度器的上下文里面： 参考如下：

Scheduler scheduler = context.getScheduler();
SchedulerContext schedulerContext = scheduler.getContext();
String jobName = schedulerContext.getString("jobName");
JobLauncher jobLauncher = (JobLauncher) schedulerContext.get("jobLauncher");
JobLocator jobLocator = (JobLocator) schedulerContext.get("jobLocator");
System.out.println("jobName : " + jobName);
System.out.println("jobLauncher : " + jobLauncher);
System.out.println("jobLocator : " + jobLocator);
SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String date = sf.format(new Date());
System.out.println("Current Time : " + date);
Job job = jobLocator.getJob(jobName);
if (job != null) {
    /*启动spring batch的批处理作业*/
    JobExecution jobExecution = jobLauncher.run(job,
            new JobParametersBuilder().addDate("date", new Date()).toJobParameters());
}

---------------------------------springbatch的配置：

1： job配置
