<T> T convertIfNecessary(Object value,
Class<T> requiredType)
throws TypeMismatchException
Conversions from String to any type will typically use the setAsText
method of the PropertyEditor class. Note that a PropertyEditor must be registered
for the given class for this to work; this is a standard JavaBeans API.
A number of PropertyEditors are automatically registered.
