1.添加依赖

            </plugins>
        </build>
    
    
    </project>

2.添加数据库数据

spring.datasource.url=jdbc:mysql:///springbatch_test?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8
    spring.datasource.username=root
    spring.datasource.password=123456
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    #用于初始化springbatch相关的表
    spring.datasource.schema=classpath:/org/springframework/batch/core/schema-mysql.sql
    spring.batch.initialize-schema=always

3.执行job

    import org.springframework.batch.core.Job;
    import org.springframework.batch.core.Step;
    import org.springframework.batch.core.StepContribution;

    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;

     */
    @Configuration
    public class JobConfig {
    
        //创建 创建job的对象
        @Autowired
        private JobBuilderFactory jobBuilderFactory;
    
        //创建 创建step的对象
        @Autowired
        private StepBuilderFactory stepBuilderFactory;
    
        @Bean
        public Job helloWorldJob() {
    
            return jobBuilderFactory.get("helloWorldJob")
                    .start(helloWorldStep())
                    .build();
    
        }
    
        @Bean
        public Step helloWorldStep() {
    
            return stepBuilderFactory.get("helloWorldStep")
                    .tasklet(new Tasklet() {
                        @Override
                        public RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {
                            System.out.println("hello world !!!");
                            return RepeatStatus.FINISHED;
                        }
                    }).build();
    
        }
    
    }

package com.springbatch._01helloworld;
    
    import org.springframework.batch.core.configuration.annotation.EnableBatchProcessing;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;

        public static void main(String[] args) {
    
            SpringApplication.run(SpringBatchConfig.class, args);
    
        }
    
    }

4.运行日志

5.查看数据库已经建好了springbatch相关的数据表
