Annotation Interface HttpExchange

@Target({TYPE,METHOD}) @Retention(RUNTIME) @Documented public @interface HttpExchange
Annotation to declare a method on an HTTP service interface as an HTTP endpoint. The endpoint details are defined statically through attributes of the annotation, as well as through the input method argument types.

Supported at the type level to express common attributes, to be inherited by all methods, such as a base URL path.

At the method level, it's more common to use one of the following HTTP method specific, shortcut annotations, each of which is itself meta-annotated with HttpExchange:

Supported method arguments:

Method Argument Description Resolver
URI Dynamically set the URL for the request, overriding the annotation's url() attribute UrlArgumentResolver
HttpMethod Dynamically set the HTTP method for the request, overriding the annotation's method() attribute HttpMethodArgumentResolver
@RequestHeader Add a request header RequestHeaderArgumentResolver
@PathVariable Add a path variable for the URI template PathVariableArgumentResolver
@RequestBody Set the body of the request RequestBodyArgumentResolver
@RequestParam Add a request parameter, either form data if "Content-Type" is "application/x-www-form-urlencoded" or query params otherwise RequestParamArgumentResolver
@CookieValue Add a cookie CookieValueArgumentResolver
