From 7c25c84ee2ea4fba56c60bd103e87e2b7a86223c Mon Sep 17 00:00:00 2001 From: Chris Beams Date: Wed, 6 Jul 2011 09:15:27 +0000 Subject: [PATCH] Deprecate/move CGLIB methods AopUtils=>ClassUtils isCglibProxy* methods in AopUtils are useful in lower-level modules, i.e. those that cannot depend on .aop. Therefore copied these methods to ClassUtils; deprecated the existing ones in AopUtils and now delegating to the new location; switched all usage of AopUtils#isCglibProxy* within the framework to use ClassUtils#isCglibProxy* instead. --- .../aop/framework/Cglib2AopProxy.java | 5 ++-- .../springframework/aop/support/AopUtils.java | 17 ++++++++---- ...tedConfigurationClassEnhancementTests.java | 4 +-- .../configuration/Spr7167Tests.java | 11 ++++---- .../org/springframework/util/ClassUtils.java | 26 +++++++++++++++++++ 5 files changed, 49 insertions(+), 14 deletions(-) diff --git a/org.springframework.aop/src/main/java/org/springframework/aop/framework/Cglib2AopProxy.java b/org.springframework.aop/src/main/java/org/springframework/aop/framework/Cglib2AopProxy.java index 255d0b76ec..46ed66b904 100644 --- a/org.springframework.aop/src/main/java/org/springframework/aop/framework/Cglib2AopProxy.java +++ b/org.springframework.aop/src/main/java/org/springframework/aop/framework/Cglib2AopProxy.java @@ -35,11 +35,11 @@ import net.sf.cglib.proxy.MethodInterceptor; import net.sf.cglib.proxy.MethodProxy; import net.sf.cglib.proxy.NoOp; import net.sf.cglib.transform.impl.UndeclaredThrowableStrategy; + import org.aopalliance.aop.Advice; import org.aopalliance.intercept.MethodInvocation; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; - import org.springframework.aop.Advisor; import org.springframework.aop.PointcutAdvisor; import org.springframework.aop.RawTargetAccess; @@ -47,6 +47,7 @@ import org.springframework.aop.TargetSource; import org.springframework.aop.support.AopUtils; import org.springframework.core.SmartClassLoader; import org.springframework.util.Assert; +import org.springframework.util.ClassUtils; import org.springframework.util.ObjectUtils; /** @@ -155,7 +156,7 @@ final class Cglib2AopProxy implements AopProxy, Serializable { Assert.state(rootClass != null, "Target class must be available for creating a CGLIB proxy"); Class proxySuperClass = rootClass; - if (AopUtils.isCglibProxyClass(rootClass)) { + if (ClassUtils.isCglibProxyClass(rootClass)) { proxySuperClass = rootClass.getSuperclass(); Class[] additionalInterfaces = rootClass.getInterfaces(); for (Class additionalInterface : additionalInterfaces) { diff --git a/org.springframework.aop/src/main/java/org/springframework/aop/support/AopUtils.java b/org.springframework.aop/src/main/java/org/springframework/aop/support/AopUtils.java index efb771f74d..f08481efba 100644 --- a/org.springframework.aop/src/main/java/org/springframework/aop/support/AopUtils.java +++ b/org.springframework.aop/src/main/java/org/springframework/aop/support/AopUtils.java @@ -63,7 +63,7 @@ public abstract class AopUtils { */ public static boolean isAopProxy(Object object) { return (object instanceof SpringProxy && - (Proxy.isProxyClass(object.getClass()) || isCglibProxyClass(object.getClass()))); + (Proxy.isProxyClass(object.getClass()) || ClassUtils.isCglibProxyClass(object.getClass()))); } /** @@ -76,27 +76,34 @@ public abstract class AopUtils { } /** - * Check whether the given object is a CGLIB proxy. + * Check whether the given object is a CGLIB proxy.
