• getSingletonTarget

  @Nullable
  public static Object getSingletonTarget​(Object candidate)

  Obtain the singleton target object behind the given proxy, if any.

  参数:

  candidate - the (potential) proxy to check

  返回:

  the singleton target object managed in a SingletonTargetSource, or null in any other case (not a proxy, not an existing singleton target)

  从以下版本开始:

  4.3.8

• ultimateTargetClass

  public static Class<?> ultimateTargetClass​(Object candidate)

  Determine the ultimate target class of the given bean instance, traversing not only a top-level proxy but any number of nested proxies as well — as long as possible without side effects, that is, just for singleton targets.

  参数:

  candidate - the instance to check (might be an AOP proxy)

  返回:

  the ultimate target class (or the plain class of the given object as fallback; never null)

  TargetClassAware.getTargetClass(), Advised.getTargetSource()

• completeProxiedInterfaces

  public static Class<?>[] completeProxiedInterfaces​(AdvisedSupport advised)

  Determine the complete set of interfaces to proxy for the given AOP configuration.

  This will always add the Advised interface unless the AdvisedSupport's "opaque" flag is on. Always adds the SpringProxy marker interface.

  参数:

  advised - the proxy config

  返回:

  the complete set of interfaces to proxy

• proxiedUserInterfaces

  public static Class<?>[] proxiedUserInterfaces​(Object proxy)

  Extract the user-specified interfaces that the given proxy implements, i.e. all non-Advised interfaces that the proxy implements.

  参数:

  proxy - the proxy to analyze (usually a JDK dynamic proxy)

  返回:

  all user-specified interfaces that the proxy implements, in the original order (never null or empty)

• equalsInProxy

  public static boolean equalsInProxy​(AdvisedSupport a,
                                      AdvisedSupport b)

  Check equality of the proxies behind the given AdvisedSupport objects. Not the same as equality of the AdvisedSupport objects: rather, equality of interfaces, advisors and target sources.

• equalsProxiedInterfaces

  public static boolean equalsProxiedInterfaces​(AdvisedSupport a,
                                                AdvisedSupport b)

  Check equality of the proxied interfaces behind the given AdvisedSupport objects.

• equalsAdvisors

  public static boolean equalsAdvisors​(AdvisedSupport a,
                                       AdvisedSupport b)

  Check equality of the advisors behind the given AdvisedSupport objects.
