Meet REST

https://spring.io/understanding/REST
entity at a URI

• use HTTP URIs to distinguish between nouns, or entities, in the system
• HTTP URIs are a natural way to describe hierarchies, or relationship
  • REST API

https://spring.io/guides/tutorials/bookmarks/

• Level2, 3?
• URI
  • represent data
  • content-negotiation mechanism to deferred to http
  • manipulation depend on http methods
    • Get, Delete, Post, Put
• Controller
  • map http request to methods
  • Spring MVC will extract those portions of the URI, and make them available as arguments of the same name that are passed to the controller method and annotated with @PathVariable
  • HttpMessageConverter s work in both directions: incoming requests bodies are converted to Java objects, and Java objects are converted into HTTP response bodies
    *validateUser UserNotFoundException HTTP status code (404) . Spring MVC provides a lotof different places to cleanly layer in generic, application-global and controller-local error handling logic.
• Test: Spring MVC provides great support for unit testing HTTP endpoints. It provides a very nice middle ground between unit-testing and integration-testing. https://spring.io/guides/tutorials/bookmarks/
