Invoke method by reflection with dynamic parameters

I'm invoking some method of Class's instance using the method.invoke(instance, args...) way but for each method inside the instance, as the invoke Javadoc rightly points out, each argument must be manually specified.

Thinking about Spring... how it could valorize parameters in controller's method behind the hood during HTTP calls? (but surely it does in a completely different way I think...)

I wonder if there's any way in Java to dynamically pass parameters in reflection (or not even reflection) without specifying each of them singularly.
