Binding request parameters with underscores in Spring MVC 3.0

Question

Consider the following requirement: request parameters have to be bound to objects using Spring MVC 3.0. The request parameters contain underscores (e.g. http://myurl:80/x?param_one=1&param_two=2). These parameters should be bound to the following object:

class MyObject {
    private Integer paramOne;
    private Integer paramTwo;

    ...
}

How would you go about doing this?

Important note: consider that there may be a substantial amount of parameters and objects like this and that it's not considered good practice to define setter methods on the objects that include underscores.

Answer 1

Rajith's answer is for controller methods specifically, and doesn't address your question originally asking how to bind underscore parameters to an object.

The hacky solution I currently have in place is to accomplish what you are actually asking is to name my setters in this style:

public void setProject_ids(List<Long> project_ids) {

Note that RequestParam cannot be applied to methods, and it does not have an effect when applied to the argument of this setter.
