Java Play Backend REST API service implementation to manage Cars and Drivers

To run the car and drivers restful service, you will need the correct version of Java and a build tool. You can build Play projects with any Java build tool. Since sbt takes advantage of Play features such as auto-reload.

Prerequisites include:

• Java Software Developer's Kit (SE) 1.8 or higher
• sbt 1.2.0 or higher (I recommend 1.3.4) the file includes an sbt distribution for your convenience.

To check your Java version, enter the following in a command window:

java -version

To check your sbt version, enter the following in a command window:

sbt sbtVersion

If you do not have the required versions, follow these links to obtain them:

• Java SE
• sbt

Run the project

To build and run the project:

1. Use a command window to change into the example project directory, for example: cd car-driver-service

2. Build the project. Enter: sbt run. The project builds and starts the embedded HTTP server. Since this downloads libraries and dependencies, the amount of time required depends partly on your connection's speed.

3. After the message Server started, ... displays, enter the following URL in a browser: http://localhost:9000/api/v1/cars

The Play application responds: { "statusCode": 401, "statusTitle": "unauthorized", "message": "Invalid/missing authorization key. Ensure you include valid authorization key in request header." }

Access Api endpoints

1. Generate authorization token from the endpoint: http://localhost:9000/api/v1/authorization/generate-key - attach a raw json object to the request e.g { "name" : "John Doe", "email" : "[email protected]" }. the response should contain the authorization token. ensure you copy it.

2. Attach the generated token as a header authorization key across all requests (Preferably use postman to test).

Test with swagger

1. Swagger interface is integrated in the project. once the project runs successfully, you can access swagger-ui from the URL : http://localhost:9000/docs/swagger-ui/index.html?url=/assets/swagger.json#/

2. You can get the list of endpoints in swagger Ui also.

Example data

1. To create driver , add raw json object to the request e.g { "username" : "doe111", "password" : "12345", "age" : 45, "firstName" : "John", "lastName" : "Doe", "onlineStatus" : "Online", "contactNumber" : "0815558555u", "gender" : "Male" }

2. To create car, add raw json object to the request e.g { "licencePlate": "Jyc-eee", "convertible": "Yes", "rating": 5, "engineType": "Electric", "colour": "Blue", "model": "2020", "manufacturer": "Innoson", "speedLimit": "360km/h" }

3. To select/deselect car, add raw json object to their endpoints e.g { "carId" : 1, "driverId" : 2 }

4. To update both car, add json payload to request e.g "licencePlate": "Jyc-eee", "convertible": "Yes", "rating": 5, "engineType": "Electric", "colour": "Blue", "model": "2020", "manufacturer": "Innoson", "speedLimit": "360km/h" }

5. To update driver, add raw json object to the request e.g { "username" : "doe111", "password" : "12345", "age" : 45, "firstName" : "John", "lastName" : "Doe", "onlineStatus" : "Online", "contactNumber" : "0815558555u", "gender" : "Male" }

6. To search for driver pass in any of the query parameters e.g : rating=4 , onlineStatus=Online or Offline , username=joh , licencePlate=8bh437-dhhs
