MitraSoft Test assignment

This repo contains code for test assignment for MitraSoft company (Junior Java Developer vacancy).

The Structure of repo:

• Server: Spring application with endpoint for REST API and also gRPC service.
• Rest Client: also a small Spring app with Thymeleaf templates for an easy user communicating with server.

Build

Apps are set up via docker-compose. Also there's a command in Makefile so after cloning this repo you can easily build and run project with:

make rebuild-docker

This command will set docker-compose down at first (if it is already runing), rebuild apps with gradle and run docker-compose up --build to run project.

API

REST

There's only one enpoint (for both GET and POST methods) to create message and get list of ones:

• http://localhost:8080/rest/message

Sending POST method:

curl -X POST http://localhost:8080/rest/message \
    -H 'Content-Type: application/json' -d '{"message":"hello rest"}'

Get all messages:

curl  http://localhost:8080/rest/message

And of course you can send and get messages by client (http://localhost:8081)

gRPC

There's implementation of gRPC in client app.

Currently gRPC sendMessage method has an issue: sending message get a StatusRuntimeException: CANCELLED: RST_STREAM closed stream. HTTP/2 error code: CANCEL. Never the less message is sent.

Also you can send messages by gRPC with grpcurl tool. For MacOs you can get it with Homebrew:

brew install grpcurl

List of grpc methods:

grpcurl -proto mitrasoft_server/src/proto/message.proto \
    localhost:9090 list org.kvas.mitrasoftserver.grpc.MessageService

Create message via grpc:

grpcurl --plaintext -proto mitrasoft_server/src/proto/message.proto \
    -d '{"message": "grpc test"}' localhost:9090 \
    org.kvas.mitrasoftserver.grpc.MessageService.createMessage

Get list of messages:

grpcurl --plaintext -proto mitrasoft_server/src/proto/message.proto \
    localhost:9090 \
    org.kvas.mitrasoftserver.grpc.MessageService.getMessages
