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 document from a source_;
JsonFormat.merge(jsonFormat, builder);

Description

Provide serialization and de-serialization of different formats based on Google’s protobuf Message. Enables overriding the default (byte array) output to text based formats such as XML, JSON and HTML.

##Example For XML output, use XmlFormat

Message someProto = SomeProto.getDefaultInstance();
String xmlFormat = XmlFormat.printToString(someProto);

For XML input, use XmlFormat

Message.Builder builder = SomeProto.newBuilder();
String xmlFormat = _load xml document from a source_;
XmlFormat.merge(xmlFormat, builder);

For Json output, use JsonFormat

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

For Json input, use JsonFormat

Message.Builder builder = SomeProto.newBuilder();
String jsonFormat = _load json document from a source_;
JsonFormat.merge(jsonFormat, builder);

For HTML output, use HtmlFormat

Message someProto = SomeProto.getDefaultInstance();
String htmlFormat = HtmlFormat.printToString(someProto);
