本文主要研究一下jetcache的CacheManager

CacheManager

jetcache-core/src/main/java/com/alicp/jetcache/CacheManager.java

public interface CacheManager {
    <K, V> Cache<K, V> getCache(String area, String cacheName);

    void putCache(String area, String cacheName, Cache cache);

    BroadcastManager getBroadcastManager(String area);

    void putBroadcastManager(String area, BroadcastManager broadcastManager);

    default <K, V> Cache<K, V> getCache(String cacheName) {
        return getCache(CacheConsts.DEFAULT_AREA, cacheName);
    }

    default void putCache(String cacheName, Cache cache){
        putCache(CacheConsts.DEFAULT_AREA, cacheName, cache);
    }

    /**
     * create or get Cache instance.
     * @see QuickConfig#newBuilder(String)
     */
    <K, V> Cache<K, V> getOrCreateCache(QuickConfig config);

    default void putBroadcastManager(BroadcastManager broadcastManager){
        putBroadcastManager(CacheConsts.DEFAULT_AREA, broadcastManager);
    }

}

CacheManager定义了getCache、putCache、getBroadcastManager、putBroadcastManager、getOrCreateCache方法，并提供了aera为default的默认getCache、putCache、putBroadcastManager方法

SimpleCacheManager

jetcache-core/src/main/java/com/alicp/jetcache/SimpleCacheManager.java

public class SimpleCacheManager implements CacheManager, AutoCloseable {

    private static final boolean DEFAULT_CACHE_NULL_VALUE = false;

    private static final Logger logger = LoggerFactory.getLogger(SimpleCacheManager.class);

    // area -> cacheName -> Cache
    private final ConcurrentHashMap<St
