  3 What is REST(Representational State Transfer)?  Software architectural style for creating RESTful web services  Allow interoperability between Internet and computer systems  Requesting systems can access and manipulate web resources represented as text  Uses a set of well-known stateless operations

  4 The REST ArchitecturalStyle  Not protocol-specific, most widely used: REST over HTTP  The representation of the state can be JSON, XML, or HTML.  The client uses the API to send the following to the server:  The identifier (URL) of the resource  The operation to perform on the resource (GET, POST, PUT, PATCH, DELETE)

  5 What is anETag?  ETag (entity tag) - HTTP response header returned by an HTTP/1.1 compliant web server used to determine change in content at a given URL.  Use ETags for caching and conditional requests.  Efficiently controls data to be retrieved.

  6 Generating REST Events There are two ways of generating REST events:  Writing an AnnotatedHandler  Writing an ApplicationListener
• 7.
  7 Projections and Excerpts Spring Data REST presents a default view of the domain model you export.  Sometimes you may need to alter the view of that model for various reasons.  Projections and excerpts serve as efficient and reduced views of resources.
