Chapter 6. @QueryParam


RESTEasy supports @QueryParam annotations with no parameter name..

The @QueryParam annotation allows mapping a URI query string parameter or url form encoded parameter to a method invocation.

GET /books?num=5

public String getBooks(@QueryParam("num") int num) {

Since RESTEasy is built on top of a Servlet, it does not distinguish between URI query strings or url form encoded parameters. Like PathParam, the parameter type can be a String, primitive, or class that has a String constructor or static valueOf() method.
