弹簧批次将不同类别中的步骤分开

Question

您好，如何将不同类中的步骤分开。 @Configurationpublic class JobBatch { @Beanpublic Job jobCC5(JobBuilderFactory jobBuilders, StepBuilderFactory stepBuilders) throws IOException {    return jobBuilders.get("jobCC5").start(chStep1(stepBuilders)).build();              }  } @Configurationpublic class Step1{@Beanpublic Step Step1(StepBuilderFactory stepBuilders) throws IOException {return stepBuilders.get("step1").<CSCiviqueDTO, String>chunk(100)    .reader(readerStep1VerifLenghtNir(null)).processor(processorStep1())        .writer(writerStep1(null)).faultTolerant().skipLimit(9).skip(Exception.class).build();}

下面是一个示例。创建一个类，在其中定义步骤：

import org.springframework.batch.core.Step;

import org.springframework.batch.core.configuration.annotation.StepBuilderFactory;

import org.springframework.batch.repeat.RepeatStatus;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

@Configuration

public class StepConfig {

    @Autowired

    private StepBuilderFactory steps;

    @Bean

    public Step step() {

        return steps.get("step")

                .tasklet((contribution, chunkContext) -> {

                    System.out.println("hello world");

                    return RepeatStatus.FINISHED;

                })

                .build();

    }

}

然后在作业配置中导入该类：

import org.springframework.batch.core.Job;

import org.springframework.batch.core.Step;

import org.springframework.batch.core.configuration.annotation.EnableBatchProcessing;

import org.springframework.batch.core.configuration.annotation.JobBuilderFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.context.annotation.Import;

@EnableBatchProcessing

@Configuration

@Import(StepConfig.class)

public class JobConfig {

    @Autowired

    private JobBuilderFactory jobs;

    @Bean

    public Job job(Step step) {

        return jobs.get("job")

                .start(step)

                .build();

    }

}

希望这有帮助。
