如何获得spring代理对象的原对象

获得spring代理对象的原对象

看代码吧：

@SuppressWarnings({"unchecked"})protected <T> T getTargetObject(Object proxy, Class<T> targetClass) throws Exception {  if (AopUtils.isJdkDynamicProxy(proxy)) {    return (T) ((Advised)proxy).getTargetSource().getTarget();  } else {    return (T) proxy; // expected to be cglib proxy then, which is simply a specialized class  }}

public class AopTargetUtils {    /**     * 获取 目标对象     * @param proxy 代理对象     * @return     * @throws Exception     */    public static Object getTarget(Object proxy) throws Exception {        if(!AopUtils.isAopProxy(proxy)) {            return proxy;//不是代理对象        }        if(AopUtils.isJdkDynamicProxy(proxy)) {            return getJdkDynamicProxyTargetObject(proxy);        } else { //cglib            return getCglibProxyTargetObject(proxy);        }    }    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;    }    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;    }    @SuppressWarnings({"unchecked"})    protected <T> T getTargetObject(Object proxy, Class<T> targetClass) throws Exception {        if (AopUtils.isJdkDynamicProxy(proxy)) {            return (T) ((Advised)proxy).getTargetSource().getTarget();        } else {            return (T) proxy; // expected to be cglib proxy then, which is simply a specialized class        }    }}

从Aop代理的对象中获取源对象

/**     * 从AOP代理对象中获得原对象的类型     * @param proxyObject     * @return     */    @SuppressWarnings("unchecked")    public static final <T> T getBeanFromProxy(T proxyObject) {        Class<?> clazz = proxyObject.getClass();        if(clazz.getName().startsWith("$Proxy")) {            try {                clazz = clazz.getSuperclass();                Field hField = clazz.getDeclaredField("h");                hField.setAccessible(true);                Object hObject = hField.get(proxyObject);                 Class<?> dynamicProxyClass = hObject.getClass();                Field advisedField = dynamicProxyClass.getDeclaredField("advised");                advisedField.setAccessible(true);                Object advisedObject = advisedField.get(hObject);                 Class<?> advisedSupportClass = advisedObject.getClass().getSuperclass().getSuperclass();                Field targetField = advisedSupportClass.getDeclaredField("targetSource");                targetField.setAccessible(true);                Object targetObject = targetField.get(advisedObject);                 Class<?> targetSourceClass = targetObject.getClass();                Field targetClassField = targetSourceClass.getDeclaredField("target");                targetClassField.setAccessible(true);                return (T) targetClassField.get(targetObject);            } catch (SecurityException e) {                e.printStackTrace();            } catch (NoSuchFieldException e) {                e.printStackTrace();            } catch (IllegalArgumentException e) {                e.printStackTrace();            } catch (IllegalAccessException e) {                e.printStackTrace();            }        }        return null;    }

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。

我也相信爱可以排除万难;只是，万难之后，又有万难。这是我更相信的。
