下面是我Pgtyp.groovy（域类）：
package marchmock2
class Pgtyp {
Date date_hour
String mv
String pagetype
Integer visits
Integer visits_ly
Integer visits_lw
String time_period
String platform
String device
String browser
static mapping = {
table "pgtyp"
version false
date_hour column: "date_hour"
mv column: "mv"
pagetype column: "pagetype"
visits column: "visits"
visits_ly column:"visits_ly"
visits_lw column:"visits_lw"
time_period column:"time_period"
platform column:"platform"
device column:"device"
browser column:"browser"
}
static constraints = {
}
}
这是我的控制器看起来像：
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中：
<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>
当我运行我的应用程序，我得到一个下拉列表，并从它选择任何选项，我得到一个错误说：
POST http://localhost:8080/marchmock2/pgtyp/ajaxGetMv 500 (Internal Server Error)
我该怎么用它做什么？ 有没有在我写这还是我误解了什么过程中的任何错误？ 任何帮助，将不胜感激。

继计算器一个答案，我改在第一次更新中提到的错误消失。 然而，当我从下拉菜单中选择“搜索引擎优化”，我得到以下错误
