Java 春季批量问题,java,spring,spring-batch,Java,Spring,Spring Batch,我有在我的项目中，我想在固定长度的文件处理数据的要求。数据文件包含一个标题行和多个细节行。标题行包含明细行的汇总和合并信息。e、 g.报告期、报告雇主、总金额等。详细信息行包含每个员工的信息。e、 g.员工供款、供款期限等。将有许多来自不同雇主的数据文件需要由工作处理 <bean id="erLoadFolderReader" class="org.springframework.batch.item.file.MultiResourceItemReader" scope="ste

  • 我希望在ItemWriter中为文件夹中处理的每个文件提供一个报表对象。因此，我可以将所有MemberRecord对象[详细信息行]添加到报表对象，并将其保存到DB[我正在使用hibernate for ORM]。我试图通过将报表对象添加到JobExecutionContext并在ItemWriter中访问它来实现这一点。因此，我从MemberRecordHeaderLineHandler类扩展了StepExecutionListenerSupport[这实现了LineCallbackHandler]。和重写beforeStep方法。我能够在beforstep方法中获取JobExecution对象，并将JobExecution对象存储到MemberRecordHeaderLineHandler类中的一个局部变量中。但当控件转到handleLine方法时，JobExecution变量为null。我正在解析标题行并将其转换为handleLine方法中的Report对象。由于JobExecution为null，因此我无法将重新写入对象添加到JobExecutionContext对象。我不确定如何将报表对象传递给ItemWriter。请告诉我如何将值从LineCallBackHandler转换为ItemWriter

  • 配置Spring集成以侦听ftp服务器
    • 

  • 一旦检测到传入文件，Spring Integration将运行作业
    • 

  • SpringBatch将处理传入文件并将数据保存到数据库中
    • 

  • 注意：要添加归档功能，您需要在Spring Batch的JobListener或StepListener上添加它
    • 

    我的要求和你的类似：处理传入文件，将正确处理的文件移到“成功”目录，将错误文件移到“错误”目录。你是如何实现的？
