NULL_CACHING_ATTRIBUTE

private static final Collection<L2CacheOperation> NULL_CACHING_ATTRIBUTE

Canonical value held in cache to indicate no caching attribute was found for this method and we don't need to look again.

attributeCache

private final Map<Object,Collection<L2CacheOperation>> attributeCache

Cache of CacheOperations, keyed by method on a specific target class.

As this base class is not marked Serializable, the cache will be recreated after serialization - provided that the concrete subclass is Serializable.

getCacheOperations

@Nullable
public Collection<L2CacheOperation> getCacheOperations(Method method,
                                                                  @Nullable
                                                                  Class<?> targetClass)

Determine the caching attribute for this method invocation.

Defaults to the class's caching attribute if no method attribute is found.

指定者:

getCacheOperations 在接口中 L2CacheOperationSource

参数:

method - the method for the current invocation (never null)

targetClass - the target class for this invocation (may be null)

返回:

L2CacheOperation for this method, or null if the method is not cacheable

getCacheKey

protected Object getCacheKey(Method method,
                             @Nullable
                             Class<?> targetClass)

Determine a cache key for the given method and target class.

Must not produce same key for overloaded methods. Must produce same key for different instances of the same method.

参数:

method - the method (never null)

targetClass - the target class (may be null)

返回:

the cache key (never null)

computeCacheOperations

@Nullable
private Collection<L2CacheOperation> computeCacheOperations(Method method,
                                                                       @Nullable
                                                                       Class<?> targetClass)

allowPublicMethodsOnly

protected boolean allowPublicMethodsOnly()

findCacheOperations

@Nullable
protected abstract Collection<L2CacheOperation> findCacheOperations(Class<?> clazz)

Subclasses need to implement this to return the caching attribute for the given class, if any.

参数:

clazz - the class to retrieve the attribute for

返回:

all caching attribute associated with this class, or null if none

findCacheOperations

@Nullable
protected abstract Collection<L2CacheOperation> findCacheOperations(Method method)

Subclasses need to implement this to return the caching attribute for the given method, if any.

参数:

method - the method to retrieve the attribute for

返回:

all caching attribute associated with this method, or null if none
