Class DefaultDocumentLoader

java.lang.Object

org.springframework.beans.factory.xml.DefaultDocumentLoader

All Implemented Interfaces:

DocumentLoader

public class DefaultDocumentLoader
extends java.lang.Object
implements DocumentLoader

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

Since:

2.0

loadDocument

public org.w3c.dom.Document loadDocument(org.xml.sax.InputSource inputSource,
                                         org.xml.sax.EntityResolver entityResolver,
                                         org.xml.sax.ErrorHandler errorHandler,
                                         int validationMode,
                                         boolean namespaceAware)
                                  throws java.lang.Exception

Load the Document at the supplied InputSource using the standard JAXP-configured XML parser.

Specified by:

loadDocument in interface DocumentLoader

Parameters:

inputSource - the source of the document that is to be loaded

entityResolver - the resolver that is to be used to resolve any entities

errorHandler - used to report any errors during document loading

validationMode - the type of validation DTD or XSD)

namespaceAware - true if support for XML namespaces is to be provided

Returns:

the loaded document

Throws:

java.lang.Exception - if an error occurs

createDocumentBuilderFactory

protected javax.xml.parsers.DocumentBuilderFactory createDocumentBuilderFactory(int validationMode,
                                                                                boolean namespaceAware)
                                                                         throws javax.xml.parsers.ParserConfigurationException

Create the DocumentBuilderFactory instance.

Parameters:

validationMode - the type of validation: DTD or XSD)

namespaceAware - whether the returned factory is to provide support for XML namespaces

Returns:

the JAXP DocumentBuilderFactory

Throws:

javax.xml.parsers.ParserConfigurationException - if we failed to build a proper DocumentBuilderFactory

createDocumentBuilder

protected javax.xml.parsers.DocumentBuilder createDocumentBuilder(javax.xml.parsers.DocumentBuilderFactory factory,
                                                                  org.xml.sax.EntityResolver entityResolver,
                                                                  org.xml.sax.ErrorHandler errorHandler)
                                                           throws javax.xml.parsers.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:

factory - the JAXP DocumentBuilderFactory that the DocumentBuilder should be created with

entityResolver - the SAX EntityResolver to use

errorHandler - the SAX ErrorHandler to use

Returns:

the JAXP DocumentBuilder

Throws:

javax.xml.parsers.ParserConfigurationException - if thrown by JAXP methods
