  - SourceHttpMessageConverter
```
public SourceHttpMessageConverter()
```
    Sets the supportedMediaTypes to text/xml and application/xml, and application/*-xml.

  - 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.
  - supports
```
public boolean supports(Class<?> clazz)
```
    从类复制的说明: AbstractHttpMessageConverter
    Indicates whether the given class is supported by this converter.
    指定者:
    supports 在类中 AbstractHttpMessageConverter<T extends Source>
    参数:
    clazz - the class to test for support
    返回:
    true if supported; false otherwise
  - readInternal
```
protected T readInternal(Class<? extends T> clazz,
                         HttpInputMessage inputMessage)
                  throws IOException,
                         HttpMessageNotReadableException
```
    从类复制的说明: AbstractHttpMessageConverter
    Abstract template method that reads the actual object. Invoked from AbstractHttpMessageConverter.read(java.lang.Class<? extends T>, org.springframework.http.HttpInputMessage).
    指定者:
    readInternal 在类中 AbstractHttpMessageConverter<T extends Source>
    参数:
    clazz - the type of object to return
    inputMessage - the HTTP input message to read from
    返回:
    the converted object
    抛出:
    IOException - in case of I/O errors
    HttpMessageNotReadableException - in case of conversion errors
  - getContentLength
```
@Nullable
protected Long getContentLength(T t,
                                @Nullable
                                MediaType contentType)
```
    从类复制的说明: AbstractHttpMessageConverter
    Returns the content length for the given type.
    By default, this returns null, meaning that the content length is unknown. Can be overridden in subclasses.
    覆盖:
    getContentLength 在类中 AbstractHttpMessageConverter<T extends Source>
    参数:
    t - the type to return the content length for
    返回:
    the content length, or null if not known
  - writeInternal
```
protected void writeInternal(T t,
                             HttpOutputMessage outputMessage)
                      throws IOException,
                             HttpMessageNotWritableException
```
    从类复制的说明: AbstractHttpMessageConverter
    Abstract template method that writes the actual body. Invoked from AbstractHttpMessageConverter.write(T, org.springframework.http.MediaType, org.springframework.http.HttpOutputMessage).
    指定者:
    writeInternal 在类中 AbstractHttpMessageConverter<T extends Source>
    参数:
    t - the object to write to the output message
    outputMessage - the HTTP output message to write to
    抛出:
    IOException - in case of I/O errors
    HttpMessageNotWritableException - in case of conversion errors
