    @HeaderParam

     

    The @HeaderParam annotation allows you to map a request HTTP header to your method invocation.

     

    GET /books?num=5

     

       
       @GET
       public String getBooks(@HeaderParam("From") String from) {
       ...
       }
    

     

    Like PathParam, your parameter type can be an String, primitive, or class that has a String constructor or static valueOf() method.  For example, MediaType has a valueOf() method and you could do:

     

    
       @PUT
       public void put(@HeaderParam("Content-Type") MediaType contentType, ...)
