所有已实现的接口:
MessageConverter, SmartMessageConverter
直接已知子类:
ProtobufJsonFormatMessageConverter
```
public class ProtobufMessageConverter
extends AbstractMessageConverter
```
An MessageConverter that reads and writes com.google.protobuf.Messages using Google Protocol Buffers.
To generate Message Java classes, you need to install the protoc binary.
This converter supports by default "application/x-protobuf" with the official "com.google.protobuf:protobuf-java" library.
"application/json" can be supported with the official "com.google.protobuf:protobuf-java-util" 3.x, with 3.3 or higher recommended.
从以下版本开始:
5.2.2
