包路径：com.github.benmanes.caffeine.cache.Cache
类名称：Cache
方法名：putAll

Cache.putAll介绍

[英]Copies all of the mappings from the specified map to the cache. The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress.
[中]将所有映射从指定映射复制到缓存。对于指定映射中从键k到值v的每个映射，此调用的效果相当于在该映射上调用put（k，v）一次。如果在操作进行过程中修改了指定的映射，则此操作的行为未定义。
