public Collection<CacheOperation> getCacheOperations(Method method, Class<?> targetClass)

Implements org.springframework.cache.interceptor.CacheOperationSource.getCacheOperations.

Doc from org.springframework.cache.interceptor.CacheOperationSource.getCacheOperations.

Return the collection of cache operations for this method, or null if the method contains no cacheable annotations.

Parameters
method:Method

the method to introspect

targetClass:Class<?>

the target class (may be null, in which case the declaring class of the method must be used)

Returns:Collection<CacheOperation>

public final CacheOperationSource[] getCacheOperationSources()

Return the CacheOperationSource instances that this CompositeCacheOperationSource combines.

isCandidateClassback to summary
public boolean isCandidateClass(Class<?> targetClass)

Overrides default org.springframework.cache.interceptor.CacheOperationSource.isCandidateClass.

Doc from org.springframework.cache.interceptor.CacheOperationSource.isCandidateClass.

Determine whether the given class is a candidate for cache operations in the metadata format of this CacheOperationSource.

If this method returns false, the methods on the given class will not get traversed for getCacheOperations introspection. Returning false is therefore an optimization for non-affected classes, whereas true simply means that the class needs to get fully introspected for each method on the given class individually.

Parameters
targetClass:Class<?>

the class to introspect

Returns:boolean

false if the class is known to have no cache operation metadata at class or method level; true otherwise. The default implementation returns true, leading to regular introspection.
