方法名：build

Caffeine.build介绍

[英]Builds a cache which does not automatically load values when keys are requested unless a mapping function is provided. Note that multiple threads can concurrently load values for distinct keys.

Consider #build(CacheLoader) instead, if it is feasible to implement a CacheLoader.

This method does not alter the state of this Caffeine instance, so it can be invoked again to create multiple independent caches.
[中]构建一个缓存，除非提供映射功能，否则在请求密钥时不会自动加载值。请注意，多个线程可以同时加载不同键的值。
如果可以实现一个CaseLoad，那么可以考虑使用“编译”（CaseloDad）。
此方法不会更改此实例的状态，因此可以再次调用它以创建多个独立缓存。
