Question

我正在尝试使用脚手架和rest api创建grails应用程序，使用脚手架一切正常，但是当我尝试从其余api获取信息时会遇到一些错误我的代码：

package estudiolegal

import grails.plugin.springsecurity.annotation.Secured
import grails.rest.Resource

import static org.springframework.http.HttpStatus.*

@Resource(uri='/api/proyectos', formats=['json', 'xml'])
@Secured(['ROLE_ADMIN','ROLE_ABOGADO','ROLE_CLIENTE'])
class ProyectoController {
    ProyectoService proyectoService

    static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]
    def index = {
        redirect action: "list"
    }

    def create() {
        respond new Proyecto(params)
    }

    def save = {
        def proyecto = new Proyecto(params)
        proyecto.addToUsuarios(applicationContext.springSecurityService.currentUser)
        proyecto.save flush: true, failOnError: true
        redirect action: "show", id: proyecto.id
    }

    def edit(Long id) {
        respond proyectoService.get(id)
    }

    def update = {
        def proyecto = Proyecto.get(params.id)
        proyecto.properties = params
        proyecto.save flush: true, failOnError: true
        redirect action: "show", id: params.id
    }

    def show (Long id){
        respond proyectoService.get(id)
    }

    def list = {
        def proyectos = Proyecto.list()
        [proyectos: proyectos]
    }

    def delete = {

        def proyecto = Proyecto.get(params.id)
        proyecto.usuarios.each {
            if(it.proyectos.contains(proyecto))
            {
                it.removeFromProyectos(proyecto)
            }
        }
        proyecto.delete flush: true, failOnError: true
        redirect action: "index"
    }

    protected void notFound() {
        request.withFormat {
            form multipartForm {
                flash.message = message(code: 'default.not.found.message', args: [message(code: 'proceso.label', default: 'Proyecto'), params.id])
                redirect action: "index", method: "GET"
            }
            '*'{ render status: NOT_FOUND }
        }
    }

}

当我尝试触发此http://localhost:8080/api/proyectos，而RestClient失败时会显示错误
