Demonstrate simple Client and Server communication using SocketServer and Socketclasses.
Here a simple protocol is defined which uses protobuf. The client reads in a json file and then creates a protobuf object from it to send it to the server. The server reads it and sends back the calculated result.
The response is also a protobuf but only with a result string.
To see the proto file see: src/main/proto which is the default location for proto files.
Gradle is already setup to compile the proto files.
The proto file can be compiled using
gradle generateProto
This will also be done when building the project.
You should see the compiled proto file in Java under build/generated/source/proto/main/java/buffers
Now you can run the client and server
Server is Java Per default on 9099 runServer
You have one example client in Java using the Protobuf protocol
Clients runs per default on host localhost, port 9099 Run Java: runClient
Java gradle runClient -Pport=9099 -Phost='localhost' gradle runServer -Pport=9099
