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?我如何使其发挥作用?
UPDATE1
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:

答案 0 :(得分:1)
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 ) } )
