正如在Batch Domain Language中叙述的,Step是一个独立封装域对象,包含了所有定义和控制实际处理信息批任务的序列。这是一个比较抽象的描述,因为任意一个Step的内容都是开发者自己编写的Job。一个Step的简单或复杂取决于开发者的意愿。一个简单的Step也许是从本地文件读取
请注意,CompositeItemWriter是委托模式的一个示例,这在Spring batch处理中很常见。委托本身可能实现回调接口,例如StepListener。如果它们确实存在,并且作为作业步骤的一部分与Spring Batch Core一起使用,那么几乎肯定需要在该步骤中手动注册它们。如果直接连接到Step的读卡器、写卡器或处理器实现了ItemStream或StepListener接口...

Transactions are important in almost any application, but handling transactions in batch applications is something a little more tricky. In standard online applications you usually have one transaction for one user action, and as a developer you normally just have to assure that your code picks up...
With the above configuration, we instruct Spring Batch framework to skip on any Exception (within a configured limit) except SAXException. This means SAXException always causes a step failure. The order of the skip() and noSkip() calls doesn’t matter. 4. Using Custom SkipPolicy Sometimes we...
