Examples of org.springframework.web.bind.ServletRequestParameterPropertyValues

org.springframework.web.bind.ServletRequestParameterPropertyValues
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. @author Rod Johnson @author Juergen Hoeller @see org.springframework.web.util.WebUtils#getParametersStartingWith
