public Object queryByPoint(int layerCode,double x,double y,double buffer){
{
Object obj=stargisQueryService.queryBySpatialOfPoint( layerCode, null, x, y, buffer);
return Result.success("查询成功",obj);
}

}

ajax: data:{"layerCode":1001,"x":9835,"y":11456,"buffer":5}

后台返回值是 layerCode 0,x 1001.0 ,y 9835.0 ,buffer 11456.0

请问这是怎么回事
