springbatch自学之路-05（flow的创建与使用）

本文主要是介绍springbatch自学之路-05（flow的创建与使用），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.配置类

package com.springbatch._03new_flow;import org.springframework.batch.core.Job;
import org.springframework.batch.core.Step;
import org.springframework.batch.core.StepContribution;
import org.springframework.batch.core.configuration.annotation.JobBuilderFactory;
import org.springframework.batch.core.configuration.annotation.StepBuilderFactory;
import org.springframework.batch.core.job.builder.FlowBuilder;
import org.springframework.batch.core.job.flow.Flow;
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.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** 任务配置器** @Package: com.springbatch._01helloworld* @ClassName: jobConfig* @author: zq* @since: 2020/5/22 21:00* @version: 1.0* @Copyright: 2020 zq. All rights reserved.*/
@Configuration
public class JobConfig {//创建 创建job的对象@Autowiredprivate JobBuilderFactory jobBuilderFactory;//创建 创建step的对象@Autowiredprivate StepBuilderFactory stepBuilderFactory;@Beanpublic Job newJob() {return jobBuilderFactory.get("newJob").start(flow1()).next(step4()).end().build();}@Beanpublic Step step3() {return stepBuilderFactory.get("step03").tasklet(new Tasklet() {@Overridepublic RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {System.out.println("step03");return RepeatStatus.FINISHED;}}).build();}@Beanpublic Step step4() {return stepBuilderFactory.get("step04").tasklet(new Tasklet() {@Overridepublic RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {System.out.println("step04");return RepeatStatus.FINISHED;}}).build();}@Beanpublic Step step2() {return stepBuilderFactory.get("step02").tasklet(new Tasklet() {@Overridepublic RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {System.out.println("step02");return RepeatStatus.FINISHED;}}).build();}@Beanpublic Step step1() {return stepBuilderFactory.get("step01").tasklet(new Tasklet() {@Overridepublic RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {System.out.println("step01");return RepeatStatus.FINISHED;}}).build();}@Beanpublic Flow flow1() {return new FlowBuilder<Flow>("flow01").start(step1()).next(step2()).next(step3()).build();}}

2.启动类

package com.springbatch._03new_flow;import org.springframework.batch.core.configuration.annotation.EnableBatchProcessing;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;/*** SpringBatchDemo项目启动类** @Package: PACKAGE_NAME* @ClassName: com.springbatch._01helloworld.SpringBatchConfig* @author: zq* @since: 2020/5/22 20:31* @version: 1.0* @Copyright: 2020 zq. All rights reserved.*/
@SpringBootApplication
@EnableBatchProcessing
public class SpringBatchConfig {public static void main(String[] args) {SpringApplication.run(SpringBatchConfig.class, args);}}

3.执行结果
