You might have noticed that POSTMAN automatically adds a header Content-Type. This is because the method implementation in controller is sending it. But if you want to consume REST based web services from your application, you would need a REST client for your application. Atomic Long; import org.springframework.stereotype.

Again, one may decide not to send the updated details in response body, and just send the location header(as in create). One of the most popular HTTP client is Apache Http Components Http Client.

This annotation eliminates the need of annotating each method with @Response Body. User Service; @Rest Controller public class Hello World Rest Controller Detailed Explanation : @Rest Controller : First of all, we are using Spring 4′s new @Rest Controller annotation.
We will also test those services using external clients. The core idea is that, rather than using complex mechanisms such as CORBA, RPC or SOAP to connect between machines, simple HTTP is used to make calls among them. @Request Body : If a method parameter is annotated with @Request Body, Spring will bind the incoming HTTP request body(for the URL mentioned in @Request Mapping for that method) to that parameter.
With Spring, we can write a simple filter which adds those CORS specific headers in each response.
