    Collection<CacheOperation>
    getCacheOperations(Method method, Class<?> targetClass)
    Return the collection of cache operations for this method, or null if the method contains no cacheable annotations.
    default boolean
    isCandidateClass(Class<?> targetClass)
    Determine whether the given class is a candidate for cache operations in the metadata format of this CacheOperationSource.

    • isCandidateClass

      default boolean isCandidateClass(Class<?> targetClass)
      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(java.lang.reflect.Method, java.lang.Class<?>) 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.

      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 returns true, leading to regular introspection.

    • getCacheOperations

      @Nullable Collection<CacheOperation> getCacheOperations(Method method, @Nullable Class<?> targetClass)
      Return the collection of cache operations for this method, or null if the method contains no cacheable annotations.
      参数:
      method - the method to introspect
      targetClass - the target class (may be null, 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
