类 CompositeCacheManager

java.lang.Object
cn.taketoday.cache.support.CompositeCacheManager
所有已实现的接口:
InitializingBean, CacheManager
public class CompositeCacheManager extends Object implements CacheManager, InitializingBean
Composite CacheManager implementation that iterates over a given collection of delegate CacheManager instances.

Allows NoOpCacheManager to be automatically added to the end of the list for handling cache declarations without a backing store. Otherwise, any custom CacheManager may play that role of the last delegate as well, lazily creating cache regions for any requested name.

Note: Regular CacheManagers that this composite manager delegates to need to return null from getCache(String) if they are unaware of the specified cache name, allowing for iteration to the next delegate in line. However, most CacheManager implementations fall back to lazy creation of named caches once requested; check out the specific configuration details for a 'static' mode with fixed cache names, if available.

  • 构造器详细资料

    • CompositeCacheManager

      public CompositeCacheManager()
      Construct an empty CompositeCacheManager, with delegate CacheManagers to be added via the "cacheManagers" property.

    • CompositeCacheManager

      public CompositeCacheManager(CacheManager... cacheManagers)
      Construct a CompositeCacheManager from the given delegate CacheManagers.
      参数:
      cacheManagers - the CacheManagers to delegate to

  • 方法详细资料

    • setCacheManagers

      public void setCacheManagers(Collection<CacheManager> cacheManagers)
      Specify the CacheManagers to delegate to.

    • setFallbackToNoOpCache

      public void setFallbackToNoOpCache(boolean fallbackToNoOpCache)
      Indicate whether a NoOpCacheManager should be added at the end of the delegate list. In this case, any getCache requests not handled by the configured CacheManagers will be automatically handled by the NoOpCacheManager (and hence never return null).

    • afterPropertiesSet

      public void afterPropertiesSet()
      指定者:
      afterPropertiesSet 在接口中 InitializingBean

    • getCache

      @Nullable public Cache getCache(String name)
      从接口复制的说明: CacheManager
      Get the cache associated with the given name.

      Note that the cache may be lazily created at runtime if the native provider supports it.

      指定者:
      getCache 在接口中 CacheManager
      参数:
      name - the cache identifier (must not be null)
      返回:
      the associated cache, or null if such a cache does not exist or could be not created

    • getCacheNames

      public Collection<String> getCacheNames()
      从接口复制的说明: CacheManager
      Get a collection of the cache names known by this manager.
      指定者:
      getCacheNames 在接口中 CacheManager
      返回:
      the names of all caches known by the cache manager
