Spring REST App

REST API in Spring to perform CRUD operations on a H2 in-memory database of Products.

REST Endpoints

• /actuator/health
• /createProduct
• /getAllProducts
• /getProductById/{id}
• /updateProductById/{id}
• /deleteProduct/{id}
• /swagger-ui/index.html

  Requirements

  Controller

• Implement the REST endpoints described in the section below
• Create a “Product” DTO to be used by the REST API
• Implement Swagger for the API
• Implement appropriate validation on the endpoints. e.g. Returning a 400 Bad Request responses fields are missing when creating a product

  Service Layer

• Implement a service layer which should act as the intermediary between the Controller and Repository layers of the application
• Should map “Product” DTO to and from “Product” entity/model (Java object used by the repository layer)

  Repository Layer

• Create an in-memory H2 database for the system to store products
• Create a repository layer using Spring JPA
• Create a “Product” entity for the repository layer
• The “Product” entity should have a unique id field that is managed by Spring JPA using sequence generation
