[springBoot] spring batch 사용자 정의 ExitStatus

job/stepExecutionListener를 이용해서 job, step 전후로 로그 출력하는 예제

jobTestConfig 🤗

package com.dev.lsy.springbatchremind.batch;

import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.batch.core.Job;
import org.springframework.batch.core.Step;
import org.springframework.batch.core.configuration.annotation.JobBuilderFactory;
import org.springframework.batch.core.configuration.annotation.StepBuilderFactory;
import org.springframework.batch.core.launch.support.RunIdIncrementer;
import org.springframework.batch.repeat.RepeatStatus;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Slf4j
@RequiredArgsConstructor
@Configuration
public class JobTestConfig {

    private final JobBuilderFactory jobBuilderFactory;
    private final StepBuilderFactory stepBuilderFactory;

    @Bean
    //job
    public Job job1() {
        return jobBuilderFactory.get("job1")
                //jobParameter 자동 증감
                .incrementer(new RunIdIncrementer())
                .listener(new CustomJobExecutionListener())
                .start(step1())
                .next(step2())
                .build();
    }

    @Bean
    //step
    public Step step1() {
        return stepBuilderFactory.get("step1")
                .tasklet(((contribution, chunkContext) -> {
                    log.info("=======================================");
                    log.info("여기는 step1입니다.");
                    log.info("=======================================");
                    return RepeatStatus.FINISHED;
                }))
                //step1에만 리스너 추가
                .listener(new CustomStepExecutionListener())
                .build();
    }

    @Bean
    //step
    public Step step2() {
        return stepBuilderFactory.get("step2")
                .tasklet(((contribution, chunkContext) -> {
                    log.info("=======================================");
                    log.info("여기는 step2입니다.");
                    log.info("=======================================");
                    return RepeatStatus.FINISHED;
                }))
                .build();
    }
}

CustomJobExecutionListener 😊

package com.dev.lsy.springbatchremind.batch;

import lombok.extern.slf4j.Slf4j;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobExecutionListener;

@Slf4j
public class CustomJobExecutionListener implements JobExecutionListener {

    @Override
    //job 시작 전 이벤트
    public void beforeJob(JobExecution jobExecution) {
        log.info("job이 시작되었다.");
        log.info("jobName ==> [{}]", jobExecution.getJobInstance().getJobName());
    }

    @Override
    //job 종료 후 이벤트
    public void afterJob(JobExecution jobExecution) {
        log.info("{}이 종료되었다.", jobExecution.getJobInstance().getJobName());
        //jobExecution 이 친구를 이용해서 시작, 종료시간을 구할 수 있다.
        long start = jobExecution.getStartTime().getTime();
        long end = jobExecution.getEndTime().getTime();

        log.info("job 소요시간 ==> [{}]", start - end);
    }
}

CustomStepExecutionListener 🤗

package com.dev.lsy.springbatchremind.batch;

import lombok.extern.slf4j.Slf4j;
import org.springframework.batch.core.ExitStatus;
import org.springframework.batch.core.StepExecution;
import org.springframework.batch.core.StepExecutionListener;

@Slf4j
public class CustomStepExecutionListener implements StepExecutionListener {

    @Override
    public void beforeStep(StepExecution stepExecution) {
        log.info("스텝 시작 전~~~");
        //데이터 추가
        stepExecution.getExecutionContext().put("name", "ironMan");
    }

    @Override
    public ExitStatus afterStep(StepExecution stepExecution) {
        log.info("스텝 종료~~~");
        //종료코드
        log.info("exitStatus ==> [{}]", stepExecution.getExitStatus().getExitCode());
        //beforeStep에서 설정한 데이터 출력
        log.info("name ==> [{}]", stepExecution.getExecutionContext().get("name"));
        return ExitStatus.COMPLETED;
    }
}
