这是我的gsp页面，当我在数据库中使用值提交它时工作正常，但是当我使用不在数据库中的某些数据查询它时失败。理想情况下它应该显示结果未找到但是它给了我一个空白页面404错误???

我在Bookingcontroller中调用的方法是
def check(){
if(request.method == 'POST') {
def bookingNo=params.bookingNo as Integer
def firstBuyerPhoneNo=params.firstBuyerPhone
println "booking number"+bookingNo+" PhoneNumber"+firstBuyerPhoneNo
Booking bookingInstance = null
try {
bookingInstance=bookingService.findByFirstBuyerPhoneAndBookingNo(firstBuyerPhoneNo,bookingNo)
}
catch (Exception ex){
ex.printStackTrace();
}
respond bookingInstance
}
}
I have just no clue that what the problem is in the form or in my controller ?
