RESTEasy supports @CookieParam
annotations with no parameter name..
The @CookieParam annotation allows the injection of the value of a cookie or an object representation of an HTTP request cookie into a method invocation
GET /books?num=5
@GET
public String getBooks(@CookieParam("sessionid") int id) {
...
}
@GET
public String getBooks(@CookieParam("sessionid") jakarta.ws.rs.core.Cookie id) {...}
Like PathParam, the parameter type can be a String, primitive, or class that has a String constructor
or static valueOf() method. It can also get an object representation of the cookie via the
jakarta.ws.rs.core.Cookie
class.
