DISCLAIMER: After the code challenge has been delivered (commit: 1a601da). Since there, I've progressed making code improvements and keeping it up-to-date from dependencies perspective and provide tooling to monitor and verify how healthy is the current code base.
You should be able to start the example application by executing com.mytaxi.MytaxiServerApplicantTestApplication, which starts a webserver on port 8080 (http://localhost:8080) and serves SwaggerUI where can inspect and try existing endpoints.
The project is based on a small web service which uses the following technologies:
- Java 1.8
- Spring MVC with Spring Boot
- Database H2 (In-Memory)
- Maven
- Intellij as IDE is preferred but not mandatory. We do provide code formatter for intellij and eclipse in the etc folder.
You should be aware of the following conventions while you are working on this exercise:
- All new entities should have an ID with type of Long and a date_created with type of ZonedDateTime.
- The architecture of the web service is built with the following components:
- DataTransferObjects: Objects which are used for outside communication via the API
- Controller: Implements the processing logic of the web service, parsing of parameters and validation of in- and outputs.
- Service: Implements the business logic and handles the access to the DataAccessObjects.
- DataAccessObjects: Interface for the database. Inserts, updates, deletes and reads objects from the database.
- DomainObjects: Functional Objects which might be persisted in the database.
- TestDrivenDevelopment is a good choice, but it's up to you how you are testing your code.
You should commit into your local git repository and include the commit history into the final result.
- Write a new Controller for maintaining cars (CRUD).
- Decide on your own how the methods should look like.
- Entity Car: Should have at least the following characteristics: license_plate, seat_count, convertible, rating, engine_type (electric, gas, ...)
- Entity Manufacturer: Decide on your own if you will use a new table or just a string column in the car table.
- Extend the DriverController to enable drivers to select a car they are driving with.
- Extend the DriverController to enable drivers to deselect a car.
- Extend the DriverDo to map the selected car to the driver.
- Add example data to resources/data.sql
First come first serve: A car can be selected by exactly one ONLINE Driver. If a second driver tries to select a already used car you should throw a CarAlreadyInUseException.
Imagine a driver management frontend that is used internally by mytaxi employees to create and edit driver related data. For a new search functionality, we need an endpoint to search for drivers. It should be possible to search for drivers by their attributes (username, online_status) as well as car characteristics (license plate, rating, etc).
- implement a new endpoint for searching or extend an existing one
- driver/car attributes as input parameters
- return list of drivers
This task is voluntarily, if you can't get enough of hacking tech challenges, implement security. Secure the API so that authentication is needed to access it. The details are up to you.
Please include instructions how to authenticate/login, so that we can test the endpoints you implemented!
