类 ServletRequestParameterPropertyValues
- java.lang.Object
- org.springframework.beans.MutablePropertyValues
- org.springframework.web.bind.ServletRequestParameterPropertyValues
- 所有已实现的接口:
Serializable,Iterable<PropertyValue>,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.
