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.
  - canRead
```
public boolean canRead(Class<?> clazz,
                       MediaType mediaType)
```
    Description copied from class: AbstractHttpMessageConverter
    This implementation checks if the given class is supported, and if the supported media types include the given media type.
    Specified by:
    canRead in interface HttpMessageConverter<Object>
    Overrides:
    canRead in class AbstractHttpMessageConverter<Object>
    Parameters:
    clazz - the class to test for readability
    mediaType - the media type to read (can be null if not specified); typically the value of a Content-Type header.
    Returns:
    true if readable; false otherwise

    Overrides:
    canWrite in class AbstractHttpMessageConverter<Object>
    Parameters:
    clazz - the class to test for writability
    mediaType - the media type to write (can be null if not specified); typically the value of an Accept header.
    Returns:
    true if writable; false otherwise
  - supports
```
protected 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)
