Grails 远程功能不工作

grails groovy

Grails 远程功能不工作,grails,groovy,hql,gorm,Grails,Groovy,Hql,Gorm,下面是我的Pgtyp.groovy（域类）：这就是我的控制器的外观： package marchmock2 import grails.converters.* import groovy.sql.Sql class PgtypController { def ajaxGetMv = { def pgtyp = Pgtyp.get(params.id) render pgtyp as JSON } def index() { } }

下面是我的Pgtyp.groovy（域类）：

这就是我的控制器的外观：

package marchmock2
import grails.converters.*
import groovy.sql.Sql 

class PgtypController {

   def ajaxGetMv = {
      def pgtyp = Pgtyp.get(params.id)
      render pgtyp as JSON
   }

   def index() { 
   }
}

最后，这是我的index.gsp：

<html>
   <head>
      <g:javascript src="jquery-1.10.2.min.js"/>
      <g:javascript src="prototype.js"/>
   </head>
   <body>
      <form>
         <g:select from="['AFFILIATES', 'SEO', 'SEM','DISPLAYADS']" name="mv" onchange="${remoteFunction(
        controller:'Pgtyp', 
        action:'ajaxGetMv', 
        params:'\'id=\' + escape(this.value)',
        onSuccess: 'printpgtyp(data)')}"></g:select>
      </form>
      <g:javascript>
         function printpgtyp(data) {
            console.log(data)
         }
      </g:javascript>
   </body>
</html>

我该怎么处理它？我写这篇文章的方式是否有任何错误，或者我是否误解了什么？任何帮助都将不胜感激

更新2

在回答stackoverflow问题后，我改为，第一次更新中提到的错误消失了。然而，当我从下拉列表中选择“SEO”时，我得到以下错误

TypeMismatchException occurred when processing request: [POST] /marchmock2/pgtyp/ajaxGetMv - parameters:

Provided id of the wrong type for class marchmock2.Pgtyp. Expected: class java.lang.Long, got class     java.lang.String. Stacktrace follows:

日志中有任何异常吗？还有为什么prototype和jquery-这肯定会让你感到悲伤…@injecteer检查问题id中的更新在你的域类上很长，你传递的是一个stringGrails为你添加了一个id字段。尝试

Pgtyp.findByMv（params.id）
