Spring Batch CommandRunner and XML

org.springframework.batch.core.launch.support.CommandLineJobRunner

This is legacy way to run spring batch program.

The simple way to make program and run spring batch program is Spring Batch Get Started.
If you are not familiar with Spring Application with gradle please read Spring Boot Gradle

Config is Configuration class.(with Annotation)

To run with CommandLineJobRunner, we need to use XML file for bean and job definition.

Let’s prepare for it.

Preparation

This example is very simple.
No database, No file input.
Only One job and one tasklet(no reader, ….)

bean definition(XML)

Create job definition file under src/main/java
job.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:batch="http://www.springframework.org/schema/batch"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://www.springframework.org/schema/batch
       http://www.springframework.org/schema/batch/spring-batch.xsd">
       
	   <bean id="transactionManager"
		class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />

  	   <bean id="jobRepository"
    		class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean">
    		<property name="transactionManager" ref="transactionManager" />
  	   </bean>

  	   <bean id="jobLauncher"
       		class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
    		<property name="jobRepository" ref="jobRepository" />
  	   </bean>
       
       <batch:job id="firstjob" job-repository="jobRepository">
        	<batch:step id="task1">
            	<batchlet
                	class="com.atmarkplant.batchsample.task.FirstTasklet" />
        	</batch:step>
    	</batch:job>
</beans>

com.atmarkplant.batchsample.task.FirstTasklet is my codes, others are spring prepared class.
In this time, I don’t use any datasource, for example, database
Job definition is under batch:job

com.atmarkplant.batchsample.task.FirstTasklet

public class FirstTasklet implements Tasklet {

	@Override
	public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
		System.out.println("task 1");
		return RepeatStatus.FINISHED;
	}
}

Run(Debug) from eclipse

To run this project project, we need to change default run configuration.

Change main class

Add arguments
