所有已实现的接口:
HttpMessageConverter<Object>
```
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.
从以下版本开始:
3.0

修饰符和类型	方法	说明
`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.

```
public Jaxb2RootElementHttpMessageConverter()
```
- 方法详细资料
  - 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)
```
