调试 Spring Batch 应用程序

Question

我在作业中定义了四个步骤，JobExecution 说完成了，但我想确保我的所有步骤都被正确调用和执行。

我们有什么方法可以调试每个步骤吗？

通过定义端点从 RestController 调用我的批处理作业

在配置文件下方找到。

@Configuration
@Log4j2
public class PickUpBatchConfig {

    @Autowired
    public JobBuilderFactory jobBuilderFactory;

    @Autowired
    public StepBuilderFactory stepBuilderFactory;


    @Bean
    public Job pickupJob() {
        return this.jobBuilderFactory.get("pickupJob")
            .listener(new JobResultListener())
            .start(a())
            .next(b())
            .next(c())
            .next(d())
            .build();
    }

    @Bean
    public Step a() {
        System.out.println("PickUpBatchConfig.a");
        return this.stepBuilderFactory.get("step1")
            .Responsechunk(0)
            .reader(new One())//dummy ,does nothing in step1
            .processor(new Two())
            .writer(new Three())
            .build();
    }

    @Bean
    public Step b() {
        System.out.println("PickUpBatchConfig.b");
        return this.stepBuilderFactory.get("step2")
            .Responsechunk(0)
            .reader(new Four())// Need to implement
            .processor(new Five())
            .writer(new Six())
            .build();
    }

    @Bean
    public Step c() {
        System.out.println("PickUpBatchConfig.c");
        return this.stepBuilderFactory.get("step3")
            .Responsechunk(0)
            .reader(new Seven())//need to implement
            .processor(new Eight())
            .writer(new nine())
            .build();
    }

    @Bean
    public Step d() {
        System.out.println("PickUpBatchConfig.d");
        return this.stepBuilderFactory.get("step4")
            .Responsechunk(0)
            .reader(new Ten())
            .processor(new Elevan())
            .writer(new Twelve())
            .build();

    }


}

JobExecution says completed

如果您可以访问作业执行并能够检查其状态，那么您可以使用 JobExecution#getStepExecutions 获取所有步骤执行并检查每个步骤的状态。
