包路径：com.github.benmanes.caffeine.cache.Caffeine
类名称：Caffeine
方法名：newBuilder

Caffeine.newBuilder介绍

[英]Constructs a new Caffeine instance with default settings, including strong keys, strong values, and no automatic eviction of any kind.

Note that while this return type is Caffeine, type parameters on the #build methods allow you to create a cache of any key and value type desired.
[中]使用默认设置构造一个新的咖啡因实例，包括强键、强值和任何类型的自动逐出。
请注意，虽然此返回类型是无效的，但是#build方法上的类型参数允许您创建所需的任何键和值类型的缓存。
