title: how to configure spring job dynamically using quartz scheduler
body: <p>I am new to Spring Batch framework and quartz scheduler. My task is to schedule a new Spring Batch job dynamically using quartz scheduler. All new spring batch job's entries are in my database with trigger expression. Problem is that for every new spring batch job coming from database , we need to wrap it in quartz's scheduler job. so means as many spring batch job will be there that many batch job class should be there to wrap them and run by quartz scheduler.</p>
  
  <p>quartz is storing all the job's and trigger entry into its own data base tables. which i have configure in config file. This job will always be quartz's job not spring batch job.
  here is my main method, here i will write my data base connection code to find out new springbatch job name and trigger expression and will bind them with quartz schedular</p>
  
  <pre><code> public static void main(String[] args) {
        try {
  
          ApplicationContext context = new ClassPathXmlApplicationContext("quartz-context.xml");              
          JobLauncher launcher=(JobLauncher) context.getBean("jobLauncher");
          JobLocator locator= (JobLocator) context.getBean("jobRegistry");
          Scheduler schedulerFactoryBean=(Scheduler) context.getBean("quartzSchedulerFactoryBean");
  
          JobDetail job = newJob(SpringBatchJob.class).withIdentity("myJob001", "group1").build();
  
          Trigger trigger1 =newTrigger().withIdentity("myTrigger001", "group1").startNow().withSchedule(simpleSchedule().withIntervalInSeconds(10).repeatForever()).build();
  
            schedulerFactoryBean.scheduleJob(job, trigger1);
  
             schedulerFactoryBean.start();              
  
        } catch (SchedulerException e) {
             e.printStackTrace();
        }
   }

  <p>Here we can see that we have jobDetail which is quartz job and  whose execute method is use to run spring batch job.</p>

  <p>here in <code>setJobName</code> method i am hard coding my spring batch job name ,
  But in my project we are having nearly 800 jobs, so acc to approarch we need to make 800 wrapper classes.</p>
  
  <p>Please help me , that how to resolve this solution by making generic class.</p>
