Secure oauth2 server with wss error messaging

Aim

Spring boot 3.0.4 based oauth2 authorization server with simple functionalities on top.
Based on preplanned steps to practice and improve spring boot skills.

Using app

Structure

• ws-client - WebSocket react client app - simple functionality to connect to ws and send incorrect login data.
• src - Spring boot app with oauth2 authorization server and user management. Reports incorrect data to ws-client via websocket.
• tools - Scripts to run app locally and in docker, configure key infrastructure and database.

Pre steps

1. Save content in ~/work/bnauth/. That means this file should have path ~/work/bnauth/README.md.
2. In case of local run, npm 9.6+, gradle 8.0+ and java 17+ are required
3. In case of docker run, Docker engine is required.
4. Scripts were tested on zsh, bash and

Localhost osx tests

Note: To test on other unix systems, change local.sh runApps() osascript commands to ones matching your system.
Eventually run script to install apps and then run them manually using steps 4 and 5 from below.

1. Run local.sh script.
   For example, sh local.sh -p keystorePasword.
   It will start postgres container, and spring boot app. It will also start react app in browser. If it doesn't, open http://localhost:3000 manually.

or

1. In project root execute ./gradlew clean build
2. In project root execute ./gradlew pgRun
3. Execute npm i in ws-client folder
4. Start spring app with your IDE or ./gradlew bootRun
5. Start react app with npm start in ws-client folder

Docker tests

1. Run docker.sh script in root folder.
   For example, sh docker.sh -p keystorePasword.
   It will start gradle installation, image build and container creation. No local runs needed except for working docker env.
