org.springframework.beans.factory.xml.DocumentLoader
Imports
javax.xml.parsers.DocumentBuilder, .DocumentBuilderFactory, .ParserConfigurationException, org.apache.commons.logging.Log, .LogFactory, org.w3c.dom.Document, org.xml.sax.EntityResolver, .ErrorHandler, .InputSource, org.springframework.lang.Nullable, org.springframework.util.xml.XmlValidationModeDetector
Spring's default DocumentLoader implementation.

Simply loads documents using the standard JAXP-configured XML parser. If you want to change the DocumentBuilder that is used to load documents, then one strategy is to define a corresponding Java system property when starting your JVM. For example, to use the Oracle DocumentBuilder, you might start your application like as follows: 

java -Djavax.xml.parsers.DocumentBuilderFactory=oracle.xml.jaxp.JXDocumentBuilderFactory MyMainClass

protected DocumentBuilder createDocumentBuilder(DocumentBuilderFactory factory, EntityResolver entityResolver, ErrorHandler errorHandler) throws ParserConfigurationException

Create a JAXP DocumentBuilder that this bean definition reader will use for parsing XML documents. Can be overridden in subclasses, adding further initialization of the builder.

Parameters

entityResolver:EntityResolver

the SAX EntityResolver to use

errorHandler:ErrorHandler

the SAX ErrorHandler to use

Returns:DocumentBuilder

the JAXP DocumentBuilder

Parameters

namespaceAware:boolean

whether the returned factory is to provide support for XML namespaces

Returns:DocumentBuilderFactory

the JAXP DocumentBuilderFactory
