Simple REST App

Abstract

This is the implementation of the simple REST service written using Spring Boot Framework. JUnit and Mockito were used for unit testing. JPA and H2 in-memory database were used for storing entities. HTTP error handlers were added.

API

LoginCounters

Endpoints for this API were created for testing purposes. They work with entities from LOGIN_COUNTER table, which consists of two columns:LOGIN(id) and REQUEST_COUNT. LOGIN_COUNTER table stores number of Users API calls.

GET /counters/

Response example

[
    {
        "login": "octocat",
        "requestCount": 5
    },
    {
        "login": "tlpchk",
        "requestCount": 2
    }
]

GET /counters/{login}

Response example (login=octocat)

{
    "login": "octocat",
    "requestCount": 5
}

Users

Fetches data from https://api.github.com/users/{login} (e.g. https://api.github.com/users/octocat) and pass it in the response. In calculations field value 6 / followers * (2 + public_repos) is placed. When followers equals zero, then "Infinity" is returned. Every call to this endpoint will increment REQUEST_COUNT value by one in LOGIN_COUNTER table for corresponding LOGIN.

GET /users/{login}
