如何从Grails服务运行GEB？

Question

我正在尝试从Grails上的Web服务运行GEB，因为我需要从页面中提取数据并在我的应用程序中使用它。 服务器用于废弃信息，然后将其返回到视图中。

如果我从grails控制台运行它可以正常工作但是当我从服务运行它时它不起作用

这是代码

package com.bamboozled
import geb.Browser
import grails.transaction.Transactional


@Transactional
class ScraperService {

Data scrapIt(String nombreCiclo, String numeroSolicitud) {
    //Variable con los datos a retornar
    def d = new Data()

    //Inicia el bot
    Browser.drive {

        go "http://some.page/page.php"

        $("form").ciclo = nombreCiclo
        $("form").nosol = numeroSolicitud
        $("form").find("input", name: "BOTONACEPTAR").click()

        def a = getAvailableWindows()

        def data = [" "," "," "," "," "]

        withWindow(a[1]) {
            data[0] = $("td")[5].text()
            data[1] = $("td")[6].text()
            data[2] = $("td")[7].text()
            data[3] = $("td")[8].text()
            data[4] = $("td")[9].text()
        }


        d.numeroSolicitud = data[0]
        d.avance = data[1]
        d.seEncuentraEn = data[2]
        d.numeroCheque = data[3]
        d.cheque = data[4]


        }
        return d
    }
}

这是我称之为的控制器

package com.bamboozled

class DataController {
    static scaffold = true

    def ScraperService

    def index() { }

    def form() {
    }

    def consulta(){
      def p = Ciclo.findAll()
      [solicitudes : p]
    }

    def resultados() {
        def d = ScraperService.scrapIt(params.nombreCiclo, params.numeroSolicitud)
        [res : d]
    }

}

当我运行它时会出现此错误

我知道如何让它运行？
