Abstract implementation of JCacheOperationSource that caches attributes for methods and implements a fallback policy: 1. specific target method; 2. declaring method.

This implementation caches attributes by method after they are first used.

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.

AbstractFallbackJCacheOperationSource()

Method Summary

Modifier and TypeMethod and Description
protected boolean
allowPublicMethodsOnly()

Should only public methods be allowed to have caching semantics?

private JCacheOperation<?>
computeCacheOperation(Method method, Class<?> targetClass)

protected abstract JCacheOperation<?>

Returns:

the cache operation associated with this method (or null if none)
findCacheOperation(Method
the method to retrieve the operation for
method, Class<?>
the target class
targetType)

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

public JCacheOperation<?>
getCacheOperation(Method
the method to introspect
method, Class<?>
the target class (may be null, in which case the declaring class of the method must be used)
targetClass)

Implements org.springframework.cache.jcache.interceptor.JCacheOperationSource.getCacheOperation.

Return the cache operations for this method, or null if the method contains no JSR-107 related metadata.
