Project "Common"

The Common is a Spring Boot application that offers a minimum set of functionalities shared by all subprojects.

• Short URL creation service: POST / creates a shortened URL from a URL in the request parameter url.
• Redirection service: GET /{id} redirects the request to a URL associated with the parameter id.
• Database service: Persistence and retrieval of ShortURL and Click objects.

The application runs an embedded Tomcat. Data is stored in the in-memory database HSQLDB.

The application can be run as follows:

$ gradle run

Now you have a shortener service running at port 8080. You can test that it works as follows:

$ curl -v -d "url=http://www.unizar.es/" -X POST http://localhost:8080/link
> POST / HTTP/1.1
> User-Agent: curl/7.37.1
> Host: localhost:8080
> Accept: */*
> Content-Length: 25
> Content-Type: application/x-www-form-urlencoded
>
* upload completely sent off: 25 out of 25 bytes
< HTTP/1.1 201 Created
< Server: Apache-Coyote/1.1
< Location: http://localhost:8080/l6bb9db44
< Content-Type: application/json;charset=UTF-8
< Transfer-Encoding: chunked

{"hash":"6bb9db44","target":"http://www.unizar.es/","uri":"http://localhost:8080/l6bb9db44","created":"2014-11-11","owner":null,"mode":307}

And now, we can navigate to the shortened URL.

$ curl -v http://localhost:8080/l6bb9db44
> GET /6bb9db44 HTTP/1.1
> User-Agent: curl/7.37.1
> Host: localhost:8080
> Accept: */*
