   > @hengyunabc 我的interFaceClass是classLoader加载的，通过下面这种方式就会出现各种异常，核心还是底层生成代理的时候没有使用interFaceClass的classLoader，反而从AppClassLoader去再次加载，然后出现异常
   > 
   > ```java
   >   public static <T> T getReferenceService(ClassLoader classLoader,T interfaceClass, Integer timeOut, String zkAddress,String version, boolean check){
   >         ClassLoader oldClassLoader = Thread.currentThread().getContextClassLoader();
   >         try {
   >             Thread.currentThread().setContextClassLoader(classLoader);
   >             ReferenceConfig<T> reference = new ReferenceConfig<>();
   >             reference.setVersion(version);
   >             reference.setApplication(applicationConfig);
   >             reference.setCheck(check);
   > //          reference.setGroup("recommend-platform");
   >             reference.setTimeout(timeOut);
   >             reference.setRegistry(new RegistryConfig("zookeeper://" + zkAddress));
   >             reference.setInterface((Class<?>) interfaceClass);
   >             T service = reference.get();
   >             return service;
   >         }finally {
   >             Thread.currentThread().setContextClassLoader(oldClassLoader);
   >         }
   >     }
   > ```
