Spring @RequestBody and @ResponseBody annotations used to bind these HTTP request/response. Lets have a closer look at these two Spring annotations. The @ResponseBody annotation tells a controller Model-View-Controller (Mvc) is a well-known design pattern for designing the GUI based applications. Needless to say, these annotations are very important for creating a web application 4. To make your method annotated with @PostMapping be able to accept @RequestBody in JSON and XML using the following annotation: @PostMapping(.

It works with @PathVariable annotation through which we can map the URI variable to one Let's create a Maven Setup. public void client (@RequestHeader (value="User-Agent") String
After learning to build Spring REST based RESTFul APIs for XML representation and JSON representation, lets build a RESTFul client to consume APIs which we have written.
