已过时。

as of Spring Framework 5.0, in favor of the standard JDK 8 Comparator.reversed()

@Deprecated
public class InvertibleComparator<T>
extends Object
implements Comparator<T>, Serializable

InvertibleComparator

public InvertibleComparator(Comparator<T> comparator)

已过时。

Create an InvertibleComparator that sorts ascending by default. For the actual comparison, the specified Comparator will be used.

参数:

comparator - the comparator to decorate
