'我刚刚开始使用spring batch。我已经完成了spring batch的所有配置。但是作业没有启动。相反,tomcat服务器正在启动。以下是我的配置

@Bean
public FlatFileItemReader<CustomerDetailsDTO> customerCsvFileReader(){
   return  new FlatFileItemReaderBuilder<CustomerDetailsDTO>()
             .name("customerCsvFileReader")
             .delimited()
             .names(JobUtils.CREATE_CUSTOMER_DTO_FIELDS)
             .linesToSkip(1)      //skip the header
             .fieldSetMapper(new CustomerDetailsDTOMapper())
             .targetType(CustomerDetailsDTO.class)
             .resource(new ClassPathResource("cust_data.csv"))
             .build();

 }


    @Bean
    public Job sampleJob(JobRepository jobRepository, Step sampleStep) {
        return new JobBuilder("sampleJob", jobRepository)
                .incrementer(new RunIdIncrementer())
                .start(sampleStep)
                .build();
    }

@Bean
public Step sampleStep(JobRepository jobRepository, PlatformTransactionManager transactionManager,ItemWriter<CustomerDetailsDTO> restItemWriter) {
    return new StepBuilder("sampleStep", jobRepository)
            .<CustomerDetailsDTO, CustomerDetailsDTO>chunk(1, transactionManager)
            .reader(customerCsvFileReader())
            .writer(restItemWriter)
            .build();
}`

但是作业根本没有启动,我在writer中使用的是RestTemplate,所以我包含了spring-boot-starter-web依赖项,我哪里出错了?
以下是日志

我是这个 Spring 批次的新手,我希望作业能运行

如果你使用的是SpringBoot 3,你需要禁用@EnableBatchProcessing,这在this问题中已经提到过

hsvhsicv

hsvhsicv2#

1.应使用@Configuration注解对包含批处理相关Bean的类进行注解
1.在配置中考虑@EnableBatchProcessing注解。
1.还要检查您的应用程序属性中是否有(实际上默认情况下是启用的,但无论如何):

spring:
  batch:
    job:
      enabled: true
