java-没有阅读器(仅写程序)的简单1步Spring Batch作业可能吗？

我想知道是否有可能编写一个春季批处理作业,而该步骤只具有一个编写器.我找不到任何有关Spring Batch文档中给定步骤固有必需内容的文档.

我希望做这样的事情：

public class MyBatchConfiguration {

@Bean
public ItemWriter<myInfo> myWriter() {
    return new MyWriter();
}

@Bean
public Step myStep(StepBuilderFactory stepBuilderFactory,
        ItemWriter<? super Object> myWriter,
        PlatformTransactionManager transactionManager) {

    return stepBuilderFactory.get("myStep")
            .chunk(1)
            .writer(myWriter).
            transactionManager(transactionManager).
            build();
}

@Bean
public Job myBatch(JobBuilderFactory jobs, Step myStep, JobExecutionListener listener) {

    return jobs.get("myBatch")
            .incrementer(new RunIdIncrementer())
            .flow(exceptionReporterStep)
            .end()
            .listener(listener)
            .build();

}

}

解决方法:

一言以蔽之.

似乎您应该使用Tasklet步骤,而不是“分块”步骤.

@Bean
public Step myStep(StepBuilderFactory stepBuilderFactory,
        Tasklet myTasklet,
        PlatformTransactionManager transactionManager) {

    return stepBuilderFactory.get("myStep")
            .tasklet(myTasklet)
            .transactionManager(transactionManager)
            .build();
}
