所有已实现的接口:
CacheManager
public class CaffeineCacheManager extends Object implements CacheManager
CacheManager implementation that lazily builds CaffeineCache instances for each getCache(java.lang.String) request. Also supports a 'static' mode where the set of cache names is pre-defined through setCacheNames(java.util.Collection<java.lang.String>), with no dynamic creation of further cache regions at runtime.

The configuration of the underlying cache can be fine-tuned through a Caffeine builder or CaffeineSpec, passed into this CacheManager through setCaffeine(com.github.benmanes.caffeine.cache.Caffeine<java.lang.Object, java.lang.Object>)/setCaffeineSpec(com.github.benmanes.caffeine.cache.CaffeineSpec). A CaffeineSpec-compliant expression value can also be applied via the "cacheSpecification" bean property.

Requires Caffeine 2.1 or higher.

  • 构造器详细资料

    • CaffeineCacheManager

      public CaffeineCacheManager()
      Construct a dynamic CaffeineCacheManager, lazily creating cache instances as they are being requested.

    • CaffeineCacheManager

      public CaffeineCacheManager(String... cacheNames)
      Construct a static CaffeineCacheManager, managing caches for the specified cache names only.

  • 方法详细资料

    • setCacheNames

      public void setCacheNames(@Nullable Collection<String> cacheNames)
      Specify the set of cache names for this CacheManager's 'static' mode.

      The number of caches and their names will be fixed after a call to this method, with no creation of further cache regions at runtime.

      Calling this with a null collection argument resets the mode to 'dynamic', allowing for further creation of caches again.

    • setCaffeine

      public void setCaffeine(com.github.benmanes.caffeine.cache.Caffeine<Object,Object> caffeine)
      Set the Caffeine to use for building each individual CaffeineCache instance.
      另请参阅:

    • setCaffeineSpec

      public void setCaffeineSpec(com.github.benmanes.caffeine.cache.CaffeineSpec caffeineSpec)
      Set the CaffeineSpec to use for building each individual CaffeineCache instance.
      另请参阅:

    • setCacheSpecification

      public void setCacheSpecification(String cacheSpecification)
      Set the Caffeine cache specification String to use for building each individual CaffeineCache instance. The given value needs to comply with Caffeine's CaffeineSpec (see its javadoc).
      另请参阅:

    • setCacheLoader

      public void setCacheLoader(com.github.benmanes.caffeine.cache.CacheLoader<Object,Object> cacheLoader)
      Set the Caffeine CacheLoader to use for building each individual CaffeineCache instance, turning it into a LoadingCache.
      另请参阅:

    • setAllowNullValues

      public void setAllowNullValues(boolean allowNullValues)
      Specify whether to accept and convert null values for all caches in this cache manager.

      Default is "true", despite Caffeine itself not supporting null values. An internal holder object will be used to store user-level nulls.

    • isAllowNullValues

      public boolean isAllowNullValues()
      Return whether this cache manager accepts and converts null values for all of its caches.

    • 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

    • 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

    • registerCustomCache

      public void registerCustomCache(String name, com.github.benmanes.caffeine.cache.Cache<Object,Object> cache)
      Register the given native Caffeine Cache instance with this cache manager, adapting it to Framework's cache API for exposure through getCache(java.lang.String). Any number of such custom caches may be registered side by side.

      This allows for custom settings per cache (as opposed to all caches sharing the common settings in the cache manager's configuration) and is typically used with the Caffeine builder API: registerCustomCache("myCache", Caffeine.newBuilder().maximumSize(10).build())

      Note that any other caches, whether statically specified through setCacheNames(java.util.Collection<java.lang.String>) or dynamically built on demand, still operate with the common settings in the cache manager's configuration.

      参数:
      name - the name of the cache
      cache - the custom Caffeine Cache instance to register

    • adaptCaffeineCache

      protected Cache adaptCaffeineCache(String name, com.github.benmanes.caffeine.cache.Cache<Object,Object> cache)
      Adapt the given new native Caffeine Cache instance to Framework's Cache abstraction for the specified cache name.
      参数:
      name - the name of the cache
      cache - the native Caffeine Cache instance
      返回:
      the FrameworkCaffeineCache adapter (or a decorator thereof)
      另请参阅:

    • createCaffeineCache

      protected Cache createCaffeineCache(String name)
      Build a common CaffeineCache instance for the specified cache name, using the common Caffeine configuration specified on this cache manager.

      Delegates to adaptCaffeineCache(java.lang.String, com.github.benmanes.caffeine.cache.Cache<java.lang.Object, java.lang.Object>) as the adaptation method to Framework's cache abstraction (allowing for centralized decoration etc), passing in a freshly built native Caffeine Cache instance.

      参数:
      name - the name of the cache
      返回:
      the FrameworkCaffeineCache adapter (or a decorator thereof)
      另请参阅:

    • createNativeCaffeineCache

      protected com.github.benmanes.caffeine.cache.Cache<Object,Object> createNativeCaffeineCache(String name)
      Build a common Caffeine Cache instance for the specified cache name, using the common Caffeine configuration specified on this cache manager.
      参数:
      name - the name of the cache
      返回:
      the native Caffeine Cache instance
