Cache.put介绍

[英]Associates the specified value with the specified key in the cache.

If the Cache previously contained a mapping for the key, the old value is replaced by the specified value. (A cache c is said to contain a mapping for a key k if and only if #containsKey(Object) would return true.)
[中]将指定的值与缓存中的指定键相关联。
如果缓存以前包含键的映射，则旧值将替换为指定值。（缓存c被称为包含密钥k的映射，当且仅当#containsKey（Object）返回true。）
