1. Start your SQL server (I used MySQL for this job). Perform commands from ini.sql file to create database and two tables.

2. Start application. HTTP server at localhost:9000 will be started.

3. Using curl utility send commands and receve answers. Also you can use your SQL server console to monitor of records creation/deletion.

Supported commands examples:

• room addition:

curl -X POST -H "Content-Type: application/json" -d '{"roomDescription":"Комната 1-35", "roomPrice":1234.56}' http://localhost:9000/rooms/create

• room delete:

curl -X POST -H "Content-Type: application/json" -d '{"roomID":2}' http://localhost:9000/rooms/delete

• get all the rooms:

curl -X GET "http://localhost:9000/rooms/list?sortedBy=room_price&order=DESC"

sortedBy - field for sort, may be "room_price" or "reg_date"

order may be "ASC" or "DESC"

• booking addition:

curl -X POST -H "Content-Type: application/json" -d '{"roomID":2, "bookingStart":"2021-01-23", "bookingEnd":"2021-02-02"}' http://localhost:9000/bookings/create

• booking delete:

curl -X POST -H "Content-Type: application/json" -d '{"bookingID":2}' http://localhost:9000/bookings/delete

• get all bookings for one room:

curl -X GET "http://localhost:9000/bookings/list?room_id=5"
