内容来自<Spring Batch 批处理框架>,作者:刘相.我只是个搬运工. 一.Spring Batch提供了独立的标签用来顶一个Job配置,分别是job.step.tasklet.chunk等.共有6个外层标签使用,如下: <batch:job id=""></batch:job><batch:flow id=""></batch:flow> <batch:job-listener><…

1.批处理: 类似于SQL里面的批处理提交 2.场景: 业务定时进行批处理操作,但是批处理的编程模型是怎么的呢? 3.开源框架 Spring Batch 4.编程模型: reader-processor-writer JobLauncher - Job - JobExecution -JobParametersValidator JobExecution result = launcher.run(job, new JobParameters()); //runJob机制 5.策略 a.批量提交…

并发处理业务 数据量大,并发度高,要支持事物,回滚,并发机制.事务.并发.监控.执行等,并不提供相应的调度功能.因此,如果我们希望批处理任务定期执行,可结合 Quartz 等成熟的调度框架实现. 业务场景: ///分布式下面的批处理系统有Hadoop,有时间可以研究一下,它需要特定的场景 ================================================================================================ 1.系统业务量很…

第一篇讲到普通job 配置 那么spring  batch 给我们提供了丰富的配置,包括定时任务,校验,复合监听器,父类,重启机制等. 下面看一个动态设置读取文件的配置 1.动态文件读取 <?xml version="1.0" encoding="UTF-8"?> <bean:beans xmlns="http://www.springframework.org/schema/batch" xmlns:bean="ht…
