public class XsltPayloadTransformer
extends AbstractXmlTransformer
implements BeanClassLoaderAware

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 results in Document payload out

Source payload in results 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)

Sets the SourceFactory.

Parameters:

sourceFactory - The source factory.

setResultFactory

public void setResultFactory(ResultFactory resultFactory)

Sets the ResultFactory.

Overrides:

setResultFactory in class AbstractXmlTransformer

Parameters:

resultFactory - The result factory.

setAlwaysUseSourceFactory

public void setAlwaysUseSourceFactory(boolean alwaysUseSourceFactory)

Specify whether to always use source factory even for directly supported payload types.

Parameters:

alwaysUseSourceFactory - true to always use the source factory.

setAlwaysUseResultFactory

public void setAlwaysUseResultFactory(boolean alwaysUseResultFactory)

Specify whether to always use result factory even for directly supported payload types

Parameters:

alwaysUseResultFactory - true to always use the result factory.

setXslParameterMappings

public void setXslParameterMappings(Map<String,Expression> xslParameterMappings)

setXsltParamHeaders

public void setXsltParamHeaders(String... xsltParamHeaders)

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

setResultType

public void setResultType(String resultType)

Overrides:

setResultType in class AbstractXmlTransformer

setResultFactoryName

public void setResultFactoryName(String resultFactoryName)

Overrides:

setResultFactoryName in class AbstractXmlTransformer

getComponentType

public String getComponentType()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this method to provide component type information.

Specified by:

getComponentType in interface NamedComponent

Overrides:

getComponentType in class IntegrationObjectSupport

onInit

protected void onInit()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this for initialization logic.

Overrides:

onInit in class AbstractXmlTransformer

doTransform

protected Object doTransform(Message<?> message)

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.

Specified by:

doTransform in class AbstractTransformer

Parameters:

message - The message.

Returns:

The result of the transformation.
