如何解决JobBuilderFactory和StepBuilderFactory的弃用警告-解网

问：

我正在使用以下工厂来设置我的 Spring Batch 应用程序：

private JobBuilderFactory jobBuilderFactory;
private StepBuilderFactory stepBuilderFactory;

但是，我收到以下弃用警告：

The type JobBuilderFactory has been deprecated since version 5.0.0 and marked for removal

这些是我正在使用的 bean 声明：

@Bean
public Step step1() {
    return stepBuilderFactory
        .get("csv-step")
        .<MSTabcNEUser, MSTabcNEUser>chunk(10)
        .reader(reader())
        .processor(processor())
        .writer(writer())
        .taskExecutor(taskExecutor())
        .build();
}

@Bean
public Job runJob() {
    return jobBuilderFactory
        .get("MSTabcNEUser")
        .flow(step1())
        .end()
        .build();
}

我还收到以下错误：

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'jobController': Unsatisfied dependency expressed through field 'job': Error creating bean with name 'runJob' defined in class path resource [com/nissan/auraQuantics/config/SpringBatchConfig.class]: Failed to instantiate [org.springframework.batch.core.Job]: Factory method 'runJob' threw exception with message: Error creating bean with name 'step1' defined in class path resource [com/nissan/auraQuantics/config/SpringBatchConfig.class]: Unsatisfied dependency expressed through method 'step1' parameter 2: No qualifying bean of type 'org.springframework.batch.item.database.JdbcBatchItemWriter<com.nissan.auraQuantics.entity.MSTAuraQuanticNEUser>' available: expected at least 1 bean which qualifies as autowire candidate.

spring-boot spring-batch

@Bean
public Step step1() {
    return new StepBuilder("csv-step", jobRepository)
        .<MSTabcNEUser, MSTabcNEUser>chunk(10, transactionManager)
        .reader(reader())
        .processor(processor())
        .writer(writer())
        .taskExecutor(taskExecutor())
        .build();
    }

@Bean
public Job runJob() {
    return new JobBuilder("MSTabcNEUser", jobRepository)
        .start(step1())
        .build();
}

最大的区别在于，您需要将 a 传递给这些构建器，将 a 传递给方法。您可以将这些字段作为字段添加到配置类中。例如：JobRepositoryPlatformTransactionManagerchunk()

private JobRepository jobRepository;
private PlatformTransactionManager transactionManager;

另请注意，接口已从支持项目集合更改为。您可能需要重构一些编写器。另请查看 Spring Batch 5.0 迁移指南。ItemWriterChunk<? extends T>
