Annotation Interface RequestHeader Annotation which indicates that a method parameter should be bound to a web request header. Supported for annotated handler methods in Spring MVC and Spring WebFlux.

A request header is an HTTP header that can be used in an HTTP request to provide information about the request context, so that the server can tailor the response. For example, the Accept-* headers indicate the allowed and preferred formats of the response.

@RequestHeader annotation binds request header values to method parameters. Given below are the available fields that you can pass optionally. defaultValue: The default value to use as a fallback. name: The name of the request header to bind to. required: Whether the header is required.

You can use the @RequestHeader annotation to bind a request header to a method argument in a controller. The following example gets the value of the Accept-Encoding and Keep-Alive headers: Java.

@RequestMapping is Spring MVC's most common and widely used annotation. It is used to map web requests onto specific handler classes and methods and make web resources addressable. Annotation has the following optional attributes.

A HTTP body (request) body is the one which carries actual HTTP request data (including form data and uploaded etc.) and HTTP response data from the server ( including files, images etc). While HTTP Request header header can't not contain actual data like as above.

The @RequestBody annotation is applicable to handler methods of Spring controllers. This annotation indicates that Spring should deserialize a request body into an object. This object is passed as a handler method parameter.
