类 CaffeineCacheManager

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.

  createNativeCaffeineCache(java.lang.String), Caffeine.build()

• setCaffeineSpec

  public void setCaffeineSpec​(com.github.benmanes.caffeine.cache.CaffeineSpec caffeineSpec)

  Set the CaffeineSpec to use for building each individual CaffeineCache instance.

  createNativeCaffeineCache(java.lang.String), Caffeine.from(CaffeineSpec)

• 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).

  createNativeCaffeineCache(java.lang.String), Caffeine.from(String)

• 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.

  createNativeCaffeineCache(java.lang.String), Caffeine.build(CacheLoader), LoadingCache

• 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 Spring'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 Spring'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 Spring CaffeineCache adapter (or a decorator thereof)

  CaffeineCache, isAllowNullValues()

• 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 Spring'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 Spring CaffeineCache adapter (or a decorator thereof)

  adaptCaffeineCache(java.lang.String, com.github.benmanes.caffeine.cache.Cache<java.lang.Object, java.lang.Object>), createNativeCaffeineCache(java.lang.String)

• 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
