synonyms-register

SpringBoot3 REST api for registering synonyms using MySQL db for storage and Keycloak for authentication.

• The register stores words with their synonyms.
• Every word could be a synonym to another word. For example, If "wash" is a synonym to "clean", then the api should return “clean” as result when we ask for the “wash” synonyms and vice versa.
• A word may have multiple synonyms.
• The register should support something we call a transitive rule. It assumes the following implementation, i.e. if "B" is a synonym to "A" and "C" a synonym to "B", then "C" should automatically, by transitive rule, also be the synonym for "A".

How to run locally

1. Clone the project and navigate to synonyms-register project folder in terminal
2. Make sure you have docker set up on your local machine
3. Run docker-compose up -d
   (this will start keycloak container, import realm and start db container)
4. Run docker exec -it mysqldb mysql -uroot -proot to access mysql shell
5. Run UPDATE mysql.user SET host='%' WHERE user='root'; and FLUSH PRIVILEGES;
   (this is to enable connection to mysql db from any host, obviously it should be used only in local setup)
6. Create two users, userreader and userwriter in keycloak admin console. If you call users differently, make sure to update postman collection.

• Open http://localhost:8080/admin in your browser and login with username admin and password admin
• Select ree_dzenan realm in left upper dropdown
• Navigate to Users in Manage menu section
• Clic on Add User button and enter userreader as Username and click Create
• Go to Credentials tab and Set Password to password, turn off Temporary flag (or in case of different password make sure to update postman collection later)
• Go to Role mapping tab and select app_reader role in Assign Role modal
• Do the same steps for userwriter and assign app_writer role to it

7. Run mvn clean package
8. Run java -jar target/synonyms-register-1.0.0-SNAPSHOT.jar
9. Import ree_dzenan.postman_collection.json into postman, generate token for both users and test endpoints
