isCandidateClass
default boolean isCandidateClass(Class<?> targetClass)
Determine whether the given class is a candidate for cache operations in the metadata format of thisCacheOperationSource
.If this method returns
false
, the methods on the given class will not get traversed forgetCacheOperations(java.lang.reflect.Method, java.lang.Class<?>)
introspection. Returningfalse
is therefore an optimization for non-affected classes, whereastrue
simply means that the class needs to get fully introspected for each method on the given class individually.- 参数:
targetClass
- the class to introspect- 返回:
false
if the class is known to have no cache operation metadata at class or method level;true
otherwise. The default implementation returnstrue
, leading to regular introspection.- 从以下版本开始:

getCacheOperations
@Nullable Collection<CacheOperation> getCacheOperations(Method method, @Nullable Class<?> targetClass)
Return the collection of cache operations for this method, ornull
if the method contains no cacheable annotations.- 参数:
method
- the method to introspecttargetClass
- the target class (may benull
, in which case the declaring class of the method must be used)- 返回:
- all cache operations for this method, or
null
if none found
