Class DefaultdocumentLoader

java.lang.Object

org.springframework.beans.factory.xml.DefaultdocumentLoader

All Implemented Interfaces:

documentLoader

public class DefaultdocumentLoader
extends 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

Method Details

loaddocument

public document loaddocument(InputSource inputSource,
 EntityResolver entityResolver,
 ErrorHandler errorHandler,
 int validationMode,
 boolean namespaceAware)
                      throws 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:

Exception - if an error occurs

createdocumentBuilderFactory

protected documentBuilderFactory createdocumentBuilderFactory(int validationMode,
 boolean namespaceAware)
                                                       throws 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:

ParserConfigurationException - if we failed to build a proper documentBuilderFactory

createdocumentBuilder

protected documentBuilder createdocumentBuilder(documentBuilderFactory factory,
 @Nullable EntityResolver entityResolver,
 @Nullable 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:

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:

ParserConfigurationException - if thrown by JAXP methods
