我正在开发一个 Spring Batch 项目，在这个项目中，我正在与 Oracle DB 进行通信，但是当我的主要方法加载XML文件时，其内容如下错误。我真的很努力使其工作。有帮助吗？
在我看来，某些bean不希望包含作用域步骤，但调试器没有给出详细的错误。
以下错误可供参考：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.jobRepository': Scope 'step' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No context holder available for step scope
