v5는 많은 것이 바뀌어서 test해보려는데 왜 Tasklet에 있는 System.out.println는 실행되지 않을까요??

EnableBatchProcessing is no longer required. I tried your sample with Spring Boot 3.0.0-RC2 (Spring Batch 5.0.0-RC2) by removing @EnableBatchProcessing and the sample works as expected.
@Configuration
public class HelloJobConfiguration{
@Bean
public DataSource batchDataSource() {
return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2)
.addScript("/org/springframework/batch/core/schema-h2.sql")
.generateUniqueName(true).build();
}
@Bean
public JdbcTransactionManager batchTransactionManager(DataSource dataSource) {
return new JdbcTransactionManager(dataSource);
}
@Bean
public Job job(JobRepository jobRepository, JdbcTransactionManager transactionManager) {
return new JobBuilder("job", jobRepository)
.start(step(jobRepository, transactionManager))
.build();
}
@Bean
public Step step(JobRepository jobRepository, PlatformTransactionManager transactionManager) {
return new StepBuilder("step", jobRepository)
.tasklet((StepContribution contribution, ChunkContext chunkContext) -> {
System.out.println("Hello, world!");
return RepeatStatus.FINISHED;
}, transactionManager)
.build();
}
