public void setProcessExternalEntities(boolean processExternalEntities)

Indicates whether external XML entities are processed when converting to a Source.

Default is false, meaning that external entities are not resolved.

supports

public 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<T extends Source>

Parameters:

clazz - the class to test for support

Returns:

true if supported; false otherwise

readInternal

protected T readInternal(Class<? extends T> clazz,
             HttpInputMessage inputMessage)
                                 throws IOException,
                                        HttpMessageNotReadableException

Description copied from class: AbstractHttpMessageConverter

Abstract template method that reads the actual object. Invoked from AbstractHttpMessageConverter.read(java.lang.Class<? extends T>, org.springframework.http.HttpInputMessage).

Specified by:

readInternal in class AbstractHttpMessageConverter<T extends Source>

Parameters:

clazz - the type of object to return

inputMessage - the HTTP input message to read from

Returns:

the converted object

Throws:

IOException - in case of I/O errors

HttpMessageNotReadableException - in case of conversion errors

Parameters:

t - the type to return the content length for

Returns:

the content length, or null if not known

Description copied from class: AbstractHttpMessageConverter

Abstract template method that writes the actual body. Invoked from AbstractHttpMessageConverter.write(T, org.springframework.http.MediaType, org.springframework.http.HttpOutputMessage).

Specified by:

writeInternal in class AbstractHttpMessageConverter<T extends Source>

Parameters:

t - the object to write to the output message
