All Implemented Interfaces:
MessageConverter, SmartMessageConverter
```
public class MarshallingMessageConverter
extends AbstractMessageConverter
```
Implementation of MessageConverter 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.

- Constructor Detail
  - MarshallingMessageConverter
```
public MarshallingMessageConverter()
```
    Default construct allowing for setMarshaller(Marshaller) and/or setUnmarshaller(Unmarshaller) to be invoked separately.
  - MarshallingMessageConverter
```
public MarshallingMessageConverter(MimeType... supportedMimeTypes)
```
    Constructor with a given list of MIME types to support.
    Parameters:
    supportedMimeTypes - the MIME types
  - MarshallingMessageConverter
```
public MarshallingMessageConverter(Marshaller marshaller)
```
    Constructor with Marshaller. If the given Marshaller also implements Unmarshaller, it is also used for unmarshalling.
    Note that all Marshaller implementations in Spring also implement Unmarshaller so that you can safely use this constructor.
    Parameters:
    marshaller - object used as marshaller and unmarshaller
- Method Detail
  - setMarshaller
```
public void setMarshaller(Marshaller marshaller)
```
    Set the Marshaller to be used by this message converter.
  - getMarshaller
```
public Marshaller getMarshaller()
```
    Return the configured Marshaller.
  - setUnmarshaller
```
public void setUnmarshaller(Unmarshaller unmarshaller)
```
    Set the Unmarshaller to be used by this message converter.
  - getUnmarshaller
```
public Unmarshaller getUnmarshaller()
```
    Return the configured unmarshaller.
  - canConvertFrom
```
protected boolean canConvertFrom(Message<?> message,
                                 Class<?> targetClass)
```
    Overrides:
    canConvertFrom in class AbstractMessageConverter
  - canConvertTo
```
protected boolean canConvertTo(Object payload,
                               MessageHeaders headers)
```
    Overrides:
    canConvertTo in class AbstractMessageConverter
  - supports
```
protected boolean supports(Class<?> clazz)
```
    Description copied from class: AbstractMessageConverter
    Whether the given class is supported by this converter.
    Specified by:
    supports in class AbstractMessageConverter
    Parameters:
    clazz - the class to test for support
    Returns:
    true if supported; false otherwise
  - convertFromInternal
```
protected Object convertFromInternal(Message<?> message,
                                     Class<?> targetClass,
                                     Object conversionHint)
```
    Description copied from class: AbstractMessageConverter
    Convert the message payload from serialized form to an Object.
    Overrides:
    convertFromInternal in class AbstractMessageConverter
    Parameters:
    message - the input message
    targetClass - the target class for the conversion
    conversionHint - an extra object passed to the MessageConverter, e.g. the associated MethodParameter (may be null}
    Returns:
    the result of the conversion, or null if the converter cannot perform the conversion
  - convertToInternal
```
protected Object convertToInternal(Object payload,
                                   MessageHeaders headers,
                                   Object conversionHint)
```
    Description copied from class: AbstractMessageConverter
    Convert the payload object to serialized form.
    Overrides:
    convertToInternal in class AbstractMessageConverter
    Parameters:
    payload - the Object to convert
    headers - optional headers for the message (may be null)
    conversionHint - an extra object passed to the MessageConverter, e.g. the associated MethodParameter (may be null}
    Returns:
    the resulting payload for the message, or null if the converter cannot perform the conversion
