maven配置

<dependency>
<groupId>com.googlecode.protobuf-java-format</groupId>

</dependency>

从protobuf转json

Message someProto = SomeProto.getDefaultInstance();
String jsonFormat = JsonFormat.printToString(someProto);

从json转protobuf

Message.Builder builder = SomeProto.newBuilder();
String jsonFormat = load json from source;
JsonFormat.merge(jsonFormat, builder);
