Spring 啓動記錄（7）

Spring建立Document對象

一、XmlBeanDefinitionReader的doLoadDocument

protected Document doLoadDocument(InputSource inputSource, Resource resource) throws Exception {
   return this.documentLoader.loadDocument(inputSource, getEntityResolver(), this.errorHandler,
         getValidationModeForResource(resource), isNamespaceAware());
}

DefaultDocumentLoader的loadDocument

@Override
public Document loadDocument(InputSource inputSource, EntityResolver entityResolver,
      ErrorHandler errorHandler, int validationMode, boolean namespaceAware) throws Exception {

   DocumentBuilderFactory factory = createDocumentBuilderFactory(validationMode, namespaceAware);
   if (logger.isDebugEnabled()) {
      logger.debug("Using JAXP provider [" + factory.getClass().getName() + "]");
   }
   DocumentBuilder builder = createDocumentBuilder(factory, entityResolver, errorHandler);
   return builder.parse(inputSource);
}
