// Struct maps the params key-value pairs to the corresponding struct object's attributes.
// The third parameter `mapping` is unnecessary, indicating the mapping rules between the
// custom key name and the attribute name(case-sensitive).
//
// Note:
//  1. The `params` can be any type of map/struct, usually a map.
//  2. The `pointer` should be type of *struct/**struct, which is a pointer to struct object
//     or struct pointer.
//  3. Only the public attributes of struct object can be mapped.
//  4. If `params` is a map, the key of the map `params` can be lowercase.
//     It will automatically convert the first letter of the key to uppercase
//     in mapping procedure to do the matching.
//     It ignores the map key, if it does not match.
