Difference between Spring Batch StepScope class and annotation?

问题

以下是翻译好的内容:

  1. StepScope 注解

StepScope

之间的区别是什么?

除了一个是注解,另一个是类之外。

StepScope 类的用途是什么?

我大致知道 StepScope 注解的用途,但是类的用途是什么?

英文:

Can someone explain what is the difference between the Spring Batch's:

StepScope Annotation

and

StepScope Class

Other than the fact one is an annotation another is a class.

What is the use of the StepScope class ?

I have an idea of what the StepScope annotation is used for but what is the use for the class ?

不要使用 StepScope 类,它是实现,允许Spring容器处理使用Step范围声明的Bean的生命周期(用@StepScope注释)。基本上,该实现将在一个步骤内返回相同的Bean,并在另一个步骤中返回一个新实例。

英文:

You should not use StepScope class, it is the implementation allowing the Spring container to handle lifetime of bean declared with Step scope (annotated with @StepScope). Basically the implementation will return the same bean inside a step and return a new instance for an other step.
