在 RemoteFunction 中为一个参数传递两个值

Question

普惠制

<g:select from="['AFFILIATES', 'CSE','DISPLAYADS','EMAIL','MOBILEWEB','OTHERS','ORGANIC','SEO', 'SEM']" name="mv" id = "mv" 
           onchange="${remoteFunction(
           controller:'Pgtyp', 
           action:'ajaxGetMv', 
           params:'\'mv=\' + escape(this.value)+\'&date_hour=\'+z+\'&date_hour=\'+ b',
           //params:'\'mv=\'+this.value',
           onSuccess: 'printpgtyp(data)')}"
></g:select> 

控制器

def pgtyp = Pgtyp.executeQuery("select p.date_hour ,p.visits, p.mv, p.browser,p.pagetype,p.platform,p.device,p.time_period from Pgtyp p where p.mv = ? and p.date_hour >= ? and p.date_hour <= ?  order by col_0_0_ asc ",[params.mv, params.date_hour,params.date_hour])

这是我尝试为一个参数传递两个值的方法。我究竟做错了什么？如何让它发挥作用？

这是我得到的错误：

ERROR:Expected positional parameter count: 3, actual parameters: [SEO, [[Ljava.lang.String;@6e5980, [Ljava.lang.String;@6e5980]] [select p.date_hour ,p.visits, p.mv, p.browser,p.pagetype,p.platform,p.device,p.time_period from Pgtyp p where p.mv = ? and p.date_hour >= ? and p.date_hour <= ? order by col_0_0_ asc ]. Stacktrace follows:

您需要在控制器中使用params.list() 方法：

def pgtyp = Pgtyp.executeQuery("select p.date_hour ,p.visits, p.mv, p.browser,p.pagetype,p.platform,p.device,p.time_period from Pgtyp p where p.mv = ? and p.date_hour >= ? and p.date_hour <= ?  order by col_0_0_ asc ", [ params.mv ] + params.list( 'date_hour' ).collect{ dateFormatter.parse( it ) } )
