Spring Batch는 @StepScope와 @JobScope 라는 아주 특별한 Bean Scope를 지원합니다. 아시다시피, Spring Bean의 기본 Scope는 singleton인데요. 그러나 아래처럼 Spring Batch 컴포넌트 (Tasklet, ItemReader, ItemWriter, ItemProcessor 등)에 @StepScope를 사용하게 되면
In Spring Batch, a Taskletis an interface that performs a single task within a Step. A typical use case for implementing a Taskletis the setup up or cleaning of resources before or after the execution of a Step. In fact, Spring Batch offers two different ways for implementing a step of a batch job: using Chunksor using a Tasklet.

Spring Batch is a great framework offering functionality for complex processings like skipping or retrying failed items, but you still need to understand what Spring Batch does to avoid problems. In this article we saw potential stumbling blocks when using skip and retry functionality.
Spring Batch is a framework to drive batch jobs, but doesn't provide support to launch them. It leaves this task to dedicated schedulers and one of them is a Spring Scheduler. A scheduler triggers launch Spring Batch jobs, by accessing the Spring Batch runtime.
