Spring Batch Quartz Java Config Example

Spring Batch
Quartz

Learn to configure Quartz scheduler to run Spring batch jobs configured using Spring boot Java configuration. Although, Spring’s default scheduler is also good, but quartz does the scheduling and invocation of tasks much better and in more configurable way. This leaves Spring batch to focus on creating batch jobs only, and let quartz execute them.

Project overview and structure

In this spring batch with quartz example, we will create two different batch jobs with different number of steps. And then we will schedule jobs execution using quart job data maps and triggers and watch the output in console.

Maven dependencies

Spring boot has inbuilt support for quartz, so all you need is to import dependencies such as spring-boot-starter-quartz and spring-boot-starter-batch.

Please note that quartz needs at least one database available to store job execution details. In this example, I am using H2 database which Spring boot supports out of the box. So include, 'h2' dependency as well.

Create batch jobs with multiple tasks

  1. Create Tasklets

    First create few tasklets. These are strategy for processing in a step within single batch job.

    import org.springframework.batch.core.StepContribution;
import org.springframework.batch.core.scope.context.ChunkContext;
import org.springframework.batch.core.step.tasklet.Tasklet;
import org.springframework.batch.repeat.RepeatStatus;

public class MyTaskOne implements Tasklet {

	public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
		System.out.println("MyTaskOne start..");

	    // ... your code
	    
	    System.out.println("MyTaskOne done..");
	    return RepeatStatus.FINISHED;
	}    
}

    public class MyTaskTwo implements Tasklet {

	public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
		System.out.println("MyTaskTwo start..");

	    // ... your code
	    
	    System.out.println("MyTaskTwo done..");
	    return RepeatStatus.FINISHED;
	}    
}

  2. Create batch jobs

    Now create spring batch jobs and configure steps in them. I am creating two batch jobs.

    • demoJobOne with 2 steps i.e. stepOne and stepTwo.
    • demoJobTwo with single step i.e. stepOne.
    import org.springframework.batch.core.Job;
import org.springframework.batch.core.Step;
import org.springframework.batch.core.configuration.annotation.EnableBatchProcessing;
import org.springframework.batch.core.configuration.annotation.JobBuilderFactory;
import org.springframework.batch.core.configuration.annotation.StepBuilderFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.howtodoinjava.demo.tasks.MyTaskOne;
import com.howtodoinjava.demo.tasks.MyTaskTwo;

@Configuration
@EnableBatchProcessing
public class BatchConfig {
	
	@Autowired
	private JobBuilderFactory jobs;

	@Autowired
	private StepBuilderFactory steps;
	
	@Bean
	public Step stepOne(){
	    return steps.get("stepOne")
	            .tasklet(new MyTaskOne())
	            .build();
	}
	
	@Bean
	public Step stepTwo(){
	    return steps.get("stepTwo")
	            .tasklet(new MyTaskTwo())
	            .build();
	}   
	
	@Bean(name="demoJobOne")
	public Job demoJobOne(){
	    return jobs.get("demoJobOne")
	            .start(stepOne())
	            .next(stepTwo())
	            .build();
	}
	
	@Bean(name="demoJobTwo")
	public Job demoJobTwo(){
	    return jobs.get("demoJobTwo")
	            .flow(stepOne())
	            .build()
	            .build();
	}
}

Create quartz job runner with QuartzJobBean

Now we need to create standard QuartzJobBean instance which we will use to execute batch jobs.

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.JobParametersBuilder;
import org.springframework.batch.core.configuration.JobLocator;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.scheduling.quartz.QuartzJobBean;

public class CustomQuartzJob extends QuartzJobBean {

	private String jobName;
	private JobLauncher jobLauncher;
	private JobLocator jobLocator;

	public String getJobName() {
		return jobName;
	}

	public void setJobName(String jobName) {
		this.jobName = jobName;
	}

	public JobLauncher getJobLauncher() {
		return jobLauncher;
	}

	public void setJobLauncher(JobLauncher jobLauncher) {
		this.jobLauncher = jobLauncher;
	}

	public JobLocator getJobLocator() {
		return jobLocator;
	}

	public void setJobLocator(JobLocator jobLocator) {
		this.jobLocator = jobLocator;
	}

	@Override
	protected void executeInternal(JobExecutionContext context) throws JobExecutionException 
	{
		try 
		{
			Job job = jobLocator.getJob(jobName);
			JobParameters params = new JobParametersBuilder()
					.addString("JobID", String.valueOf(System.currentTimeMillis()))
					.toJobParameters();

			jobLauncher.run(job, params);
		} 
		catch (Exception e) 
		{
			e.printStackTrace();
		}
	}
}

Configure quartz job details and triggers in SchedulerFactoryBean

  1. Now time to configure create quartz JobDetail and triggers and register them to spring’s context.
  2. JobDetail instances contain information about QuartzJobBean and information to inject using JobDataMap.
  3. Trigger instances are also created to configure batch job execution time and frequency.
  4. Finally, add job details and triggers to SchedulerFactoryBean which configure quartz and manages its lifecycle as part of the Spring application context. It automatically starts the scheduler on initialization and shut it down on destruction.

import java.util.Properties;

	}
}

Customize quartz with properties file

In quartz, You can control lots of things from simple properties file. e.g.

#scheduler name will be "MyScheduler"
org.quartz.scheduler.instanceName = MyScheduler

#maximum of 3 jobs can be run simultaneously
org.quartz.threadPool.threadCount = 3

#All of Quartz data is held in memory (rather than in a database). 
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

Demo

Before running the application, make sure you have disabled batch jobs auto-start feature in application.properties file.

#Disable batch job's auto start 
spring.batch.job.enabled=false

#enable h2 databse console
spring.h2.console.enabled=true

Now run the application as Spring batch application and check the logs.

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App
{
	public static void main(String[] args) 
	{
		SpringApplication.run(App.class, args);
	}
}

Clearly both Spring batch jobs are executing based on their schedule configured in quartz triggers.
