Triple-Samples

Triple is an application layer's protocol based on HTTP/2, which supports interoperating with GRPC protocol naturally using Protobuf serialization. For non-protobuf applications, triple provides a compatible mode to upgrade without code modifications. So it is smooth to migrate to triple.

This sample project contains most scenarios of Dubbo and non-Dubbo interoperation.

For beginners

1. Start a zookeeper or config other registry in org.apache.dubbo.sample.tri.ApiProvider and org.apache.dubbo.sample.tri.ApiConsumer
2. Build with mvn clean install to generate protobuf classes.
3. Run org.apache.dubbo.sample.tri.ApiProvider
4. Run org.apache.dubbo.sample.tri.ApiConsumer

For dubbo2 or non-prototbuf users

Run org.apache.dubbo.sample.tri.ApiWrapperProvider and org.apache.dubbo.sample.tri.ApiWrapperConsumer.

Dubbo3 will wrap request and response with a protobuf wrapper automatically, so it is still compatible with GRPC.

For Dubbo developers

Code under test folder is a general interoperation test suite for both Dubbo/Dubbo and Dubbo/GRPC.

Dubbo/Dubbo test

1. Run org.apache.dubbo.sample.tri.TriGrpcProvider
2. Run org.apache.dubbo.sample.tri.TriPbConsumerTest , org.apache.dubbo.sample.tri.TriWrapConsumerTest and org.apache.dubbo.sample.tri.TriGenericTest

Dubbo/GRPC test

GRPC --> Dubbo

1. Run org.apache.dubbo.sample.tri.TriGrpcProvider
2. Run org.apache.dubbo.sample.tri.grpc.GrpcConsumerTest

Dubbo --> GRPC

1. Run org.apache.dubbo.sample.tri.grpc.GrpcProvider
2. Run org.apache.dubbo.sample.tri.TriPbConsumerTest
