Nacos ECO project

grpc-nacos-java

this is common way of gRPC Nacos Java integration. Please feel free to add more features with this repo by sending pull requests and raising a issue.

Features

• grpc client usage
• grpc server builder and starter
• integrate with Nacos
• Automatic service registration and discovery
• Round robin LoadBalancer which supported by gRPC

Requirements

Latest stable Apache Maven, Maven 3.2.5 or above. Note that this is build-time requirement.

Runtime requirement: JDK 8 is a recommend to run this application.

Building

You may clone this project and step into grpc-nacos-java sub directory before read on.

# git clone https://github.com/Moriadry/grpc-nacos-java
# cd grpc-nacos-java

Run the following command to build the project(Java 1.8 is required to build the master branch).

  mvn clean install

Getting started by demo

Step 1: Start nacos server

Start a Nacos naming server is a must.

Step 2: Config for projects

Check the necessary config here You can copy this proto to your project. And do pay attention to the config usage.

`nacos_uri` means the uri of Nacos naming uri to register.
`grpc_nacos_port` means the port of Grpc server,which is needed by both server and client.

use `GrpcNacosOptions.getDescriptor().getOptions().getExtension(GrpcNacosProto.grpcNacosPort)` to get configuration of grpc port,
and `GrpcNacosOptions.getDescriptor().getOptions().getExtension(GrpcNacosProto.nacosUri)` represents the configuration of nacos registry url. 

Step 3: Start gRPC server

cd grpc-nacos-java-example
mvn exec:java@server-demo

Step 4: Start gRPC client

mvn exec:java@client-demo

Step 5: Result

Calling result will be print out on the screen.

Next Steps

• Golang will be supported when nacos-go-sdk provided.

• More features welcome to be requested.
