默認情況下，spring會按照如下規則生成代理：

當類有實現接口，spring會生成JdkDynamicAopProxy代理

當類沒有實現接口，spring會生成CglibAopProxy代理

如果想強制spring生成CglibAopProxy代理，可以<aop:config proxy-target-class="true"> </aop:config>

[email protected]，請按照如下的方式設置 <aop:aspectj-autoproxy> 的 proxy-target-class 屬性：<aop:aspectj-autoproxy proxy-target-class="true"

---------------------------------------------------------------------當通過JdkDynamicAopProxy實現代理的時候，如何獲取到目標對象-------------------------------------------------------------

private static Object getJdkDynamicProxyTargetObject(Object proxy) throws Exception {
　　Field h = proxy.getClass().getSuperclass().getDeclaredField("h");
　　h.setAccessible(true);
　　AopProxy aopProxy = (AopProxy) h.get(proxy);

　　Field advised = aopProxy.getClass().getDeclaredField("advised");
　　advised.setAccessible(true);

　　Object target = ((AdvisedSupport) advised.get(aopProxy)).getTargetSource().getTarget();

　　return target;
}

--------------------------------------------------------------------當通過CglibAopProxy實現代理的時候，如何獲取目標對象---------------------------------------------------------------------------

private static Object getCglibProxyTargetObject(Object proxy) throws Exception {
Field h = proxy.getClass().getDeclaredField("CGLIB$CALLBACK_0");
h.setAccessible(true);
Object dynamicAdvisedInterceptor = h.get(proxy);

Field advised = dynamicAdvisedInterceptor.getClass().getDeclaredField("advised");
advised.setAccessible(true);

Object target = ((AdvisedSupport) advised.get(dynamicAdvisedInterceptor)).getTargetSource().getTarget();

return target;
}
