All Implemented Interfaces:

HttpMessageConverter<Object>

public class MarshallingHttpMessageConverter
extends AbstractXmlHttpMessageConverter<Object>

Implementation of HttpMessageConverter that can read and write XML using Spring's Marshaller and Unmarshaller abstractions.

This converter requires a Marshaller and Unmarshaller before it can be used. These can be injected by the constructor or bean properties.

By default, this converter supports text/xml and application/xml. This can be overridden by setting the supportedMediaTypes property.

3.0

Constructor Detail

MarshallingHttpMessageConverter

public MarshallingHttpMessageConverter()

Construct a new MarshallingHttpMessageConverter with no Marshaller or Unmarshaller set. The marshaller and unmarshaller must be set after construction by invoking setMarshaller(Marshaller) and setUnmarshaller(Unmarshaller) .

MarshallingHttpMessageConverter

public MarshallingHttpMessageConverter(Marshaller marshaller)

Construct a new MarshallingMessageConverter with the given Marshaller set.

If the given Marshaller also implements the Unmarshaller interface, it is used for both marshalling and unmarshalling. Otherwise, an exception is thrown.

Note that all Marshaller implementations in Spring also implement the Unmarshaller interface, so that you can safely use this constructor.

Parameters:

marshaller - object used as marshaller and unmarshaller

MarshallingHttpMessageConverter

public MarshallingHttpMessageConverter(Marshaller marshaller,
                                       Unmarshaller unmarshaller)

Construct a new MarshallingMessageConverter with the given Marshaller and Unmarshaller.

Parameters:

marshaller - the Marshaller to use

unmarshaller - the Unmarshaller to use

Method Detail

setMarshaller

public void setMarshaller(Marshaller marshaller)

Set the Marshaller to be used by this message converter.

setUnmarshaller

public void setUnmarshaller(Unmarshaller unmarshaller)

Set the Unmarshaller to be used by this message converter.

supports

public boolean supports(Class<?> clazz)

Description copied from class: AbstractHttpMessageConverter

Indicates whether the given class is supported by this converter.

Specified by:

supports in class AbstractHttpMessageConverter<Object>

Parameters:

clazz - the class to test for support

Returns:

true if supported; false otherwise

readFromSource

protected Object readFromSource(Class<?> clazz,
                                HttpHeaders headers,
                                Source source)
                         throws IOException

Description copied from class: AbstractXmlHttpMessageConverter

Abstract template method called from AbstractHttpMessageConverter.read(Class, HttpInputMessage).

Specified by:

readFromSource in class AbstractXmlHttpMessageConverter<Object>

Parameters:

clazz - the type of object to return

headers - the HTTP input headers

source - the HTTP input body

Returns:

the converted object

Throws:

IOException - in case of I/O errors

writeToResult

protected void writeToResult(Object o,
                             HttpHeaders headers,
                             Result result)
                      throws IOException

Description copied from class: AbstractXmlHttpMessageConverter

Abstract template method called from AbstractXmlHttpMessageConverter.writeInternal(Object, HttpOutputMessage).

Specified by:

writeToResult in class AbstractXmlHttpMessageConverter<Object>

Parameters:

o - the object to write to the output message

headers - the HTTP output headers

result - the HTTP output body

Throws:

IOException - in case of I/O errors
