java - com.google.common.collect.MapMaker 中的过期时间

Question

我刚刚下载了最新版本的 Guava

<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>20.0-hal</version>
</dependency>

我发现 MapMaker 类不再有方法 expiration，我发现它很有用，但我还没有找到任何替代方法。

Answer 1

参见MapMakerMigration · google/guava Wiki :

All caching related methods on MapMaker have been deprecated in favor of similar methods in CacheBuilder, and are scheduled for upcoming deletion.

看起来它首先在版本 8.0 中被弃用。并在 13.0 之前删除.
