질문입니다.

Program Arguments가 없어서 VM options에

-Dspring.batch.job.names=helloWorldJob

이와같이 설정하여 실행하였고 test파일의 경우 -Dspring.batch.job.names=helloWorldJob -DfileName=test.csv

이렇게 설정하였는데

fileName의 경우 null이 나오는데

현재 저의 코드는 package com.example.SpringBatchTutorial.job.ValidatedParam; import lombok.RequiredArgsConstructor; import org.junit.Test; import org.springframework.batch.core.*; import org.springframework.batch.core.configuration.annotation.JobBuilderFactory; import org.springframework.batch.core.configuration.annotation.JobScope; import org.springframework.batch.core.configuration.annotation.StepBuilderFactory; import org.springframework.batch.core.configuration.annotation.StepScope; import org.springframework.batch.core.launch.JobLauncher; import org.springframework.batch.core.launch.support.RunIdIncrementer; import org.springframework.batch.core.scope.context.ChunkContext; import org.springframework.batch.core.step.tasklet.Tasklet; import org.springframework.batch.repeat.RepeatStatus; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; /* desc : 파일 이름 파라미터 전달 그리고 검증 run : --spring.batch.job.names=helloWorldJob - fileName=test.csv * */ @Configuration @RequiredArgsConstructor public class ValidatorParamJobConfig { @Autowired private JobBuilderFactory jobBuilderFactory; @Autowired private StepBuilderFactory stepBuilderFactory; @Autowired private JobLauncher jobLauncher; @Autowired private Job validatedParamJob; @Test public void testJob() throws Exception { // JobParameters에 fileName을 명시적으로 추가 JobParameters jobParameters = new JobParametersBuilder() .addString("fileName", "test.csv") // fileName 전달 .toJobParameters(); // Job 실행 jobLauncher.run(validatedParamJob, jobParameters); } @Bean public Job ValidatedParamJob(Step ValidatedParamStep){ return jobBuilderFactory.get("ValidatedParamJob") .incrementer(new RunIdIncrementer()) .start(ValidatedParamStep) .build(); } @JobScope @Bean public Step ValidatedParamStep(Tasklet ValidatedParamTasklet){ return stepBuilderFactory.get("ValidatedParamStep") .tasklet(ValidatedParamTasklet) .build(); } @Bean @StepScope public Tasklet ValidatedParamTasklet(@Value("#{jobParameters['fileName']}") String fileName){ return new Tasklet() { @Override public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception { System.out.println(fileName); System.out.println("Validated Param Tasklet"); return RepeatStatus.FINISHED; } }; } }이렇게 되어있습니다.
