REST-PermutationGenerator Implemented most of given tasks. Users can: choose max length of a String, choose min length of a String, choose how many String to be generated, choose chars to generate from, get saved words from database, get active threads count. App works in parallel so it can take multiple request from users. Maximum pool of threads can be changed in AsyncConfiguration file - for now it's 3. App is using H2 Database, we can connect to it through | localhost:8080/h2-console | when app is running username: sa password: password To test my api i used Postman and we can send POST request as seen on screenshot
