A simple implementation of shortened url in Java, Spring Boot, Postgres and Redis.

After cloning the project go to the root of the project and run:

./gradlew bootRun

The gradle will download the dependencies and start the application.

To generate a short url we should use the following instructions.

Endpoint:

POST /shortened-url/url

Request:

{
    "originalUrl":"http://my-long-url",
    "alias": "my-alias",
    "timeToExpiration": 1636213524
}

The fields alias and timeToExpiration are optionals.

Response: 201

{
    "domainApp": "http://localhost:8080/shortened-url",
    "alias": "65066c97-d9e5-485f-b772-0f02e2a22171",
    "shortUrl": "http://localhost:8080/shortened-url/65066c97-d9e5-485f-b772-0f02e2a22171"
}

Getting the existent short url:

Endpoint:

GET /shortened-url/url/{alias}

localhost:8080/shortened-url/url/GnYZH3O0

Response: 302

Redirect to the orignal url.

I am using Locust https://locust.io/ as a tool for loading test.

It is a tool make in Python that is very easy to use.

The script are into the folder named load-test, so go to there and run locust, after that, locust will start an application server to run the tests.
