Question

我的应用程序最近从Spring 3.x升级到Spring 4.x（通过将我们的应用程序移动到Spring-boot，最新版本）

我们有一些看起来像这样的AOP并且在升级之前工作正常:( cglib用于创建代理）

<bean id="myproxycreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
    <property name="proxyTargetClass" value="true"/>
    <property name="interceptorNames">
        <list>
            <value>myInterceptor</value>
        </list>
    </property>
    <property name="beanNames">
        <list>
            <value>myBean</value>
        </list>
    </property>
</bean>

在我们的应用程序嵌入spring-boot启动应用程序之后，我们现在在启动时遇到这些类型的错误（请注意，这些类中没有代理是'最终'）但是看起来尽管proxyTargetClass为= TRUE，但是Spring试图做一个“代理代理??”

如果我们更改proxyTargetClass = FALSE，我猜它会使用基于JDK的代理吗？然而，当我们这样做时，我们的AOP拦截器不再被称为...如何分类这个问题。

任何帮助表示感谢。

春季升级后：无法生成类com.sun.proxy的CGLIB子类。$ Proxy
