Is there any way to convert java8 Map<K,V> to ConcurrentMap<K,V> other than iterating manually over all entities?
There exist the constructor in https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ConcurrentHashMap.html
因此,你
ConcurrentHashMap(Map<? extends K,? extends V> m) Creates a new map with the same mappings as the given map.
您可使用<代码>。 并行 HashMap(Map<);? ? 有效期 V> m) Constructionor for example to adopt in a Map and Construction a Con CurrentHashMap.
如果你唯一需要的是对这一地图的同步看法,你可以使用
java.util.Collections#synchronizedMap
通常,这是你想要的,因为“同步化”地图的总体表现更糟。 但是,如果你希望对你的地图有具体的“同步观点”,这一解决办法就可以解决一些问题。
