play protobuf

This library provides a way to easily handle protobuf objects as input and output in play controllers. There is also functionality to build controllers are routes from gRPC definitions in proto files.

Internals

Extend ProtobufParser class with your protobuf class as part of the definition. Use it as a typical play bodyparser See test/java/protos/com/example/tutorial/PhoneNumberParser.java as an example parser and test/java/protos/com/example/tutorial/HomeController.java as a sample controller

Code Generation

Use the ServiceCodeGeneratorUtil class to generate controllers, parsers, and routes from proto files that have gRPC style definitions. Example: new ServiceCodeGeneratorUtil().generateClassFiles("service.proto", "app", true); new ServiceCodeGeneratorUtil().generateRoutesFiles("service.proto", "conf/routes");

Testing
