Question

How get a user of this class, from a lastName, not from the id.
in my example i use a REST web service.

My class USER.groovy in Grails:

class User {
     String firstName
     String lastName
     String zipcode }

class UrlMappings {
       static mappings = {

               /user/$id" (controller: "user") {
                            action = [GET: "show"]
               }
       }
}

def show = {
   User user = User.get(params.id)
   if (user) {
      render user as JSON
   } else {
      SendNotFoundResponse()
   }

 }

如我所知,你不了解如何通过其他领域来查询领域的问题。例如,你可以使用:

User.findByFirstName(params.id)
