java.lang.Object
infra.aop.framework.AopProxyUtils
public abstract class AopProxyUtils extends Object
Utility methods for AOP proxy factories. Mainly for internal use within the AOP framework.

See AopUtils for a collection of generic AOP utility methods which do not depend on AOP framework internals.

    • 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)

    • 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)

    • completeJdkProxyInterfaces

      public static Class<?>[] completeJdkProxyInterfaces(Class<?>... userInterfaces)
      Complete the set of interfaces that are typically required in a JDK dynamic proxy generated by Infra AOP.

      Specifically, StandardProxy, Advised, and DecoratingProxy will be appended to the set of user-specified interfaces.

      This method can be useful when registering proxy hints for Infra AOT support, as demonstrated in the following example which uses this method via a static import. 

       RuntimeHints hints = ...
 hints.proxies().registerJdkProxy(completeJdkProxyInterfaces(MyInterface.class));
      参数:
      userInterfaces - the set of user-specified interfaces implemented by the component to be proxied
      返回:
      the complete set of interfaces that the proxy should implement
      抛出:
      IllegalArgumentException - if a supplied Class is null, is not an interface, or is a sealed interface

    • 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 StandardProxy marker interface.

      参数:
      advised - the proxy config
      返回:
      the complete set of interfaces to proxy

    • completeProxiedInterfaces

      public static Class<?>[] completeProxiedInterfaces(AdvisedSupport advised, boolean decoratingProxy)
      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 StandardProxy marker interface.

      参数:
      advised - the proxy config
      decoratingProxy - whether to expose the DecoratingProxy interface
      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.
