普通代理类 方法 调用 super.xxx , 因此内部调用 无法拦截


 public final void method1()
  {
    try
    {
      MethodInterceptor tmp4_1 = this.CGLIB$CALLBACK_0;
      if (tmp4_1 == null)
      {
        tmp4_1;
        CGLIB$BIND_CALLBACKS(this);
      }
      if (this.CGLIB$CALLBACK_0 != null) {
        return;
      }
      // note here !!!!!!
      super.method1();
      return;
    }
    catch (RuntimeException|Error localRuntimeException)
    {
      throw localRuntimeException;
    }
    catch (Throwable localThrowable)
    {
      throw new UndeclaredThrowableException(localThrowable);
    }
  }
