2. DESIGN

com.jepark.springboot
com.jepark.springboot.controller
com.jepark.springboot.model
com.jepark.springboot.service
com.jepark.springboot.util
@SpringBootApplication(scanBasePackages={"com.jepark.springboot"})
public class SpringBootRestApiExam1Application
This is what our REST API does:
GET request to /api/user/ returns a list of users
GET request to /api/user/1 returns the user with ID 1
POST request to /api/user/ with a user object as JSON creates a new user
PUT request to /api/user/3 with a user object as JSON updates the user with ID 3
DELETE request to /api/user/4 deletes the user with ID 4
DELETE request to /api/user/ deletes all the users

3. DATA
