我是 grails 的新手,正在尝试为我的 web 服务构建后端,应用程序只能访问 web 服务,而不能直接访问数据库。
package backend
import org.grails.plugins.wsclient.service.WebService
class BackendController {
WebService webService
def index = {
def wsdlUrl = "http://localhost8080/BackendService/Backend?wsdl"
def proxy = webService.getClient(wsdlUrl)
def result = proxy.getAll()
render(text:result);
}
}
并抛出这个错误
Error 500: Executing action [index] of controller [backend.BackendController] caused exception: org.apache.cxf.interceptor.Fault: None of the policy alternatives can be satisfied.
如何解决该错误?
