SpringBatch的起源是2006年埃森哲(Accenture)将自己的私有批处理框架开源,与SpringSource(Spring Framework 的背后公司)合作发布了Spring Batch 1.0。 后续SpringBatch的设计也经过多次重构,但是在今天看来已经存在严重的设计问题,对于性能优化、代码复用都极为不友好。本文将分析SpringBatch的设计问题,并结合NopBatch这一新...

As shown in our batch processing example, a batch process is typically encapsulated by aJobconsisting of multipleSteps. EachSteptypically has a singleItemReader,ItemProcessor, andItemWriter. AJobis executed by aJobLauncher, and metadata about configured and executed jobs is stored in aJobRepository...

2.2. Enabling Batch Processing When ‘spring-boot-starter-batch‘ is added, Spring boot automatically configures the Spring Batch related beansusingBatchAutoConfiguration.java. The use of@EnableBatchProcessingis discouraged by Spring Batch if we are using Spring Boot 3because it disables the auto-conf...
