REST API in Spring to perform CRUD operations on a H2 in-memory database of Products.
/actuator/health/createProduct/getAllProducts/getProductById/{id}/updateProductById/{id}/deleteProduct/{id}/swagger-ui/index.html
- 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
- 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)
- 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
