## 类 AopNamespaceUtils

- java.lang.Object
- - org.springframework.aop.config.AopNamespaceUtils

-     public abstract class AopNamespaceUtils
      extends Object

  Utility class for handling registration of auto-proxy creators used internally by the '`aop`' namespace tags.

  Only a single auto-proxy creator should be registered and multiple configuration elements may wish to register different concrete implementations. As such this class delegates to `AopConfigUtils` which provides a simple escalation protocol. Callers may request a particular auto-proxy creator and know that creator, or a more capable variant thereof, will be registered as a post-processor.
