I. Overview

1. Goal

We'll build a Spring Boot Application in that: - HATEOAS REST Service provides interface for interacting with Customer Database. - Client calls API by using JQuery Ajax POST/GET: + POST: submit new Order for specific Customer by CustomerId (assume that we have had Customer Database before: 3 customers, we just add new Order information). + GET: retrieve Customer Data (Id, Name, Orders List) by CustomerId

When displaying Customer Data for HTTP GET, our application can also show links to current Customer and its Orders.

2. Technology

- Java 1.8 - Maven 3.3.9 - Spring Tool Suite – Version 3.8.4.RELEASE - Spring Boot: 1.5.4.RELEASE

3. Project Structure

• HATEOAS REST Service:

• Customer class extends Spring HATEOAS ResourceSupport.
• CustomerRepository provides repository methods and custom finder methods for CustomerController to interact with Customer, Order database.
• CustomerController is a REST Controller which has request mapping methods for RESTful requests such as:
  /{id}, /{id}/orders, /postorder , /getcustomer/{id}
• Request and Response class define data structures for returned data of HTTP POST/GET.

- JQuery Ajax POST/GET: + home.jsp contains form and elements for submitting POST/GET request. + ajax() POST/GET methods in get.js, post.js Javascript file. + WebController maps url to home.jsp page. - Configuration for JSP page and static resources in application.properties - Dependencies for Spring HATEOAS, WEB MVC, Tomcat in pom.xml

II. Practice

1. Create Spring Boot project

- Using Spring Tool Suite/Eclipse to create Project (WAR packaging), ServletInitializer and SpringBootApplication class will be created automatically. - Add Dependencies to pom.xml file:
