    - #### getAspectInstance

          public Object getAspectInstance()

      从接口复制的说明: `AspectInstanceFactory`
      Create an instance of this factory's aspect.
      指定者:
        `getAspectInstance` 在接口中 `AspectInstanceFactory`
      返回:
        the aspect instance (never `null`)

    - #### isMaterialized

          @Nullable
          public ClassLoader getAspectClassLoader()

      从接口复制的说明: `AspectInstanceFactory`
      Expose the aspect class loader that this factory uses.
      指定者:
        `getAspectClassLoader` 在接口中 `AspectInstanceFactory`
      返回:
        the aspect class loader (or `null` for the bootstrap loader)
      另请参阅:
        `ClassUtils.getDefaultClassLoader()`

    - #### getAspectMetadata

          public AspectMetadata getAspectMetadata()
