[GitHub] SkyDriveCN opened a new issue #2044: dubbo:annotation标签在消费者端无法实例化Controller

SkyDriveCN opened a new issue #2044: dubbo:annotation标签在消费者端无法实例化Controller
URL: https://github.com/apache/incubator-dubbo/issues/2044
 
 
   您好，我使用dubbo2.6.2版本时在服务端使用**dubbo:annotation**标签能够正常将服务注册到zookeeper。
   但是在消费端使用**dubbo:annotation**标签扫描controller类所在包时，访问该controller中的方法一直404，改成使用dubbo:reference标签引用服务就可以了。请问这个问题是由什么原因造成的？
   **这是服务端的配置：**
