- org.springframework.http.converter.AbstractHttpMessageConverter<com.google.protobuf.Message>
- - org.springframework.http.converter.protobuf.ProtobufHttpMessageConverter

所有已实现的接口:
HttpMessageConverter<com.google.protobuf.Message>
```
public class ProtobufHttpMessageConverter
extends AbstractHttpMessageConverter<com.google.protobuf.Message>
```
An HttpMessageConverter that reads and writes Messages using Google Protocol Buffers.
By default, it supports "application/x-protobuf", "text/plain", "application/json", "application/xml", while also writing "text/html".
To generate Message Java classes, you need to install the protoc binary.
Requires Protobuf 2.6 and Protobuf Java Format 1.4, as of Spring 4.3.
从以下版本开始:
4.1

`protected boolean`	`canWrite(MediaType mediaType)`	This method overrides the parent implementation, since this HttpMessageConverter can also produce `MediaType.HTML "text/html"` ContentType.
`protected MediaType`	`getDefaultContentType(com.google.protobuf.Message message)`	Returns the default content type for the given type.
`protected com.google.protobuf.Message`	`readInternal(Class<? extends com.google.protobuf.Message> clazz, HttpInputMessage inputMessage)`	Abstract template method that reads the actual object.
`protected boolean`	`supports(Class<?> clazz)`	Indicates whether the given class is supported by this converter.
`protected void`	`writeInternal(com.google.protobuf.Message message, HttpOutputMessage outputMessage)`	Abstract template method that writes the actual body.

  - supports
```
protected 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<com.google.protobuf.Message>
    参数:
    clazz - the class to test for support
    返回:
    true if supported; false otherwise
  - getDefaultContentType
```
protected MediaType getDefaultContentType(com.google.protobuf.Message message)
```
    从类复制的说明: AbstractHttpMessageConverter
    Returns the default content type for the given type. Called when AbstractHttpMessageConverter.write(T, org.springframework.http.MediaType, org.springframework.http.HttpOutputMessage) is invoked without a specified content type parameter.
    By default, this returns the first element of the supportedMediaTypes property, if any. Can be overridden in subclasses.
    覆盖:
    getDefaultContentType 在类中 AbstractHttpMessageConverter<com.google.protobuf.Message>
    参数:
    message - the type to return the content type for
    返回:
    the content type, or null if not known
  - readInternal
```
protected com.google.protobuf.Message readInternal(Class<? extends com.google.protobuf.Message> 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<com.google.protobuf.Message>
    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
  - canWrite
```
protected boolean canWrite(MediaType mediaType)
```
    This method overrides the parent implementation, since this HttpMessageConverter can also produce MediaType.HTML "text/html" ContentType.
    覆盖:
    canWrite 在类中 AbstractHttpMessageConverter<com.google.protobuf.Message>
    参数:
    mediaType - the media type to write, can be null if not specified. Typically the value of an Accept header.
    返回:
    true if the supported media types are compatible with the media type, or if the media type is null
  - writeInternal
```
protected void writeInternal(com.google.protobuf.Message message,
                             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<com.google.protobuf.Message>
    参数:
    message - 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
