Class ServletRequestParameterPropertyValues

java.lang.Object

org.springframework.beans.MutablePropertyValues

org.springframework.web.bind.ServletRequestParameterPropertyValues

All Implemented Interfaces:

Serializable, PropertyValues

public class ServletRequestParameterPropertyValues
extends MutablePropertyValues

PropertyValues implementation created from parameters in a ServletRequest. Can look for all property values beginning with a certain prefix and prefix separator (default is "_").

For example, with a prefix of "spring", "spring_param1" and "spring_param2" result in a Map with "param1" and "param2" as keys.

This class is not immutable to be able to efficiently remove property values that should be ignored for binding.
