All Implemented Interfaces:

```
public class Jaxb2RootElementHttpMessageConverter
extends AbstractJaxb2HttpMessageConverter<Object>
```
Implementation of HttpMessageConverter that can read and write XML using JAXB2.
This converter can read classes annotated with XmlRootElement and XmlType, and write classes annotated with XmlRootElement, or subclasses thereof.
Note: When using Spring's Marshaller/Unmarshaller abstractions from spring-oxm, you should use the MarshallingHttpMessageConverter instead.

3.0

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`canRead(Class<?> clazz, MediaType mediaType)`	This implementation checks if the given class is supported, and if the supported media types include the given media type.
`boolean`	`canWrite(Class<?> clazz, MediaType mediaType)`	This implementation checks if the given class is supported, and if the supported media types include the given media type.
`boolean`	`isProcessExternalEntities()`	Return whether XML external entities are allowed.
`boolean`	`isSupportDtd()`	Return whether DTD parsing is supported.
`protected Source`	`processSource(Source source)`
`protected Object`	`readFromSource(Class<?> clazz, HttpHeaders headers, Source source)`	Abstract template method called from `AbstractHttpMessageConverter.read(Class, HttpInputMessage)`.
`void`	`setProcessExternalEntities(boolean processExternalEntities)`	Indicate whether external XML entities are processed when converting to a Source.
`void`	`setSupportDtd(boolean supportDtd)`	Indicate whether DTD parsing should be supported.
`protected boolean`	`supports(Class<?> clazz)`	Indicates whether the given class is supported by this converter.
`protected void`	`writeToResult(Object o, HttpHeaders headers, Result result)`	Abstract template method called from `AbstractXmlHttpMessageConverter.writeInternal(Object, HttpOutputMessage)`.

```
public Jaxb2RootElementHttpMessageConverter()
```
- Method Detail
  - setSupportDtd
```
public void setSupportDtd(boolean supportDtd)
```
    Indicate whether DTD parsing should be supported.
    Default is false meaning that DTD is disabled.
  - isSupportDtd
```
public boolean isSupportDtd()
```
    Return whether DTD parsing is supported.
  - setProcessExternalEntities
```
public void setProcessExternalEntities(boolean processExternalEntities)
```
    Indicate whether external XML entities are processed when converting to a Source.
    Default is false, meaning that external entities are not resolved.
    Note: setting this option to true also automatically sets setSupportDtd(boolean) to true.
  - isProcessExternalEntities
```
public boolean isProcessExternalEntities()
```
    Return whether XML external entities are allowed.
  - 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
  - canWrite
```
public boolean canWrite(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:
    canWrite in interface HttpMessageConverter<Object>
    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)
                         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:

  - processSource
```
protected Source processSource(Source source)
```
  - writeToResult
```
protected void writeToResult(Object o,
                             HttpHeaders headers,
