A web application that manages an auction house.

Java Challenge

Build

You can build the project with Maven.

Compile the application:

./mvnw compile      # or mvn compile

Test:

./mvnw test         # or mvn test

If you just want to launch the webapp:

./mvnw spring-boot:run

Some notes about the Web Application (not exhaustive)

• The format I use to send and retrieve data is in JSON.
• I use GET, POST, and DELETE as HTTP requests.
• I chose Spring (Spring Boot) to develop the application.
• Auction houses have a unique name.
• An auction house can be deleted if its auctions are not running.
• Auctions are distinct.
• An auction cannot be deleted if it is running.
• A user bid can be registered if and only if the bidding price is higher that the auction current price and the auction is running.
• An auction house/auction cannot be added twice.
• An user cannot bid twice in row in a same auction.
• An auction house is preloaded for test purpose.

Test the app

Auction house

• Add an auction house:

curl -i -H "Content-Type: application/json" -d '{"name":"foo"}' localhost:8080/auction-houses

• List all auction houses:

curl -i localhost:8080/auction-houses

• Delete an auction house:

curl -i -X DELETE localhost:8080/auction-houses/{id}

Auction

• List all auctions, for a given auction house:

curl -i localhost:8080/auction-houses/{auction_house_id}/auctions?filter=[not_started|running|terminated]

• Add an auction, for a given auction house:

curl -i -H "Content-Type: application/json" -d '{"name":"foo", "description":"bar", "starting_time":"2019-08-16", "end_time":"2019-08-16T15:45:42Z", "start_price":"42.0", "current_price":"64.0"}' localhost:8080/auction-houses/{auction_house_id}/auctions

NB:

1. current_price is optional, the other fields are mandatory.
2. The two dates must follow the ISO-8601 standard. Otherwise, the request will fail.

• Delete an auction, for a given auction house:

curl -i -X DELETE localhost:8080/auction-houses/{auction_house_id}/auctions/{1}

User bid

• Let a user bid, for a given auction:

curl -i -H "Content-Type: application/json" -d '{"name":"foo","price":"42.0"}' localhost:8080/auctions/{auction_id}/userbids

• List all user bids that has happened until now, for a given auction:

curl -i localhost:8080/auctions/{auction_id}/userbids

The user bids are sorted by dates, from the most recent to the oldest one.

• For a terminated auction, return the winner:

curl -i localhost:8080/auctions/{auction_id}/userbids/winner
