Class XsltPayloadTransformer

java.lang.Object
  org.springframework.integration.transformer.AbstractTransformer
      org.springframework.integration.xml.transformer.XsltPayloadTransformer

All Implemented Interfaces:

Transformer

public class XsltPayloadTransformer
extends AbstractTransformer

Thread safe XSLT transformer implementation which returns a transformed Source, Document, or String. If alwaysUseSourceResultFactories is false (default) the following logic occurs

String payload in results in String payload out

Document payload in Document payload out

Source payload in Result payload out, type will be determined by the ResultFactory, DomResultFactory by default. If an instance of ResultTransformer is registered this will be used to convert the result.

If alwaysUseSourceResultFactories is true then the ResultFactory and SourceFactory will be used to create the Source from the payload and the Result to pass into the transformer. An instance of ResultTransformer can also be provided to convert the Result prior to returning

Method Detail

setSourceFactory

public void setSourceFactory(SourceFactory sourceFactory)

Parameters:

sourceFactory -

setResultFactory

public void setResultFactory(ResultFactory resultFactory)

Parameters:

resultFactory -

setAlwaysUseSourceResultFactories

public void setAlwaysUseSourceResultFactories(boolean alwaysUserSourceResultFactories)

Forces use of ResultFactory and SourceFactory even for directly supported payloads such as String and Document

Parameters:

alwaysUserSourceResultFactories -

doTransform

protected java.lang.Object doTransform(Message<?> message)
                                throws java.lang.Exception

Description copied from class: AbstractTransformer

Subclasses must implement this method to provide the transformation logic. If the return value is itself a Message, it will be used as the result. Otherwise, any non-null return value will be used as the payload of the result Message.
