## Class JsrBeanDefinitionDocumentReader

- java.lang.Object
- - org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader
  - - org.springframework.batch.core.jsr.configuration.xml.JsrBeanDefinitionDocumentReader

- All Implemented Interfaces:
    org.springframework.beans.factory.xml.BeanDefinitionDocumentReader

      public class JsrBeanDefinitionDocumentReader
      extends org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader

  `DefaultBeanDefinitionDocumentReader` extension to hook into the pre processing of the provided XML document, ensuring any references to property operators such as jobParameters and jobProperties are resolved prior to loading the context. Since we know these initial values upfront, doing this transformation allows us to ensure values are retrieved in their resolved form prior to loading the context and property operators can be used on any element. This document reader will also look for references to artifacts by the same name and create new bean definitions to provide the ability to create new instances.
