Question

我创建了一个新的grails应用并执行grails install-plugin rest。应用构建。现在我将插件页面中的示例：http://grails.org/plugin/rest添加到引导程序中并具有：

import l2http.*
class BootStrap {

  def init = { servletContext ->
    withHttp(uri: "http://www.google.com") {
      def html = get(path : '/search', query : [q:'Groovy'])
      assert html.HEAD.size() == 1
      assert html.BODY.size() == 1
    }
  }
  def destroy = {
  }
}

此崩溃时出现以下错误：

Answer 1

withHttp或rest-plugin添加的任何方法都被注入Controllers和Services而不是BootStrap类。请在服务或控制器中尝试。干杯。伯纳
