@Inherited @Target({TYPE,METHOD}) @Retention(RUNTIME) @Documented public @interface Produces
MessageBodyWriter can produce.
 If not specified then a container will assume that any type can be produced.
 Method level annotations override a class level annotation. A container
 is responsible for ensuring that the method invoked is capable of producing
 one of the media types requested in the HTTP request. If no such method is
 available the container must respond with a HTTP "406 Not Acceptable" as
 specified by RFC 2616.
 A method for which there is a single-valued @Produces
 is not required to set the media type of representations that it produces:
 the container will use the value of the @Produces when
 sending a response.

 Use of the comma-separated form allows definition of a common string constant
