org.springframework.binding.support.BeanPropertyAccessStrategy
An implementation of MutablePropertyAccessStrategy that provides access to the properties of a JavaBean.
As this class delegates to a BeanWrapper for property access, there is full support for nested properties, enabling the setting/getting of properties on subproperties to an unlimited depth. @author Oliver Hutchison @author Arne Limburg @see org.springframework.beans.BeanWrapper
