Spring Batch Commandline Arugments

Spring Batch Commandline Arguments

To use commandline arguments, it’s easy to use org.springframework.batch.core.launch.support.CommandLineJobRunner
About CommandLineJobRunner, I already posted one Spring Batch CommandRunner and XML

Prepare tasklet to use arguments

public class ArgumentTask implements Tasklet {

	private String param1;
	
	@Override
	public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
		System.out.println("Arguments");
		
		System.out.println("Argument 1 :" + param1);
		return RepeatStatus.FINISHED;
	}
	
	/**
	 * Required
	 * @param param1
	 */
	public void setParam1(String param1) {
		this.param1 = param1;
	}
}

Setter is required to set parameter

XML to receive

This is batch tasklet configuration(not full)

<batch:job id="argumentjob" job-repository="jobRepository">
        	<batch:step id="task2">
            	<batchlet scope="step"
                	class="com.atmarkplant.batchsample.task.ArgumentTask">
                	<property name="param1" value="#{jobParameters&#91;'param1'&#93;}"></property>
                </batchlet>
        	</batch:step>
</batch:job>

#{jobParameters[‘param1’] is parameter reference. param1 is key

Run configuration

Add key=value to run(debug) arguments

job.xml argumentjob param1=xxxx
