其中ExtTraversableResolver代码如下：
import java.lang.annotation.ElementType;
import javax.validation.Path;
import javax.validation.TraversableResolver;

public class ExtTraversableResolver implements TraversableResolver {

public final boolean isReachable(Object traversableObject, Path.Node traversableProperty, Class<?> rootBeanType, Path pathToTraversableObject, ElementType elementType) {
return true;
}

public final boolean isCascadable(Object traversableObject, Path.Node traversableProperty, Class<?> rootBeanType, Path pathToTraversableObject, ElementType elementType) {

}
}
