[GitHub] [incubator-dubbo] Alfred-Wong opened issue #3827: 通过spring配置文件方式消费dubbo服务，在servlet中注入了该dubbo服务，报代理错误
- [ ] I have searched the [issues](https://github.com/apache/incubator-dubbo/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [FAQ](https://github.com/apache/incubator-dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.
### test
* Dubbo version: 2.7.0
* Operating System version:
* Java version: 1.8
### Steps to reproduce this issue
1. 通过spring配置文件方式消费dubbo服务
2.在servlet中注入了该dubbo服务
3. 服务启动报错，报could not generate CGLIB subclass of class org.apache.dubbo.common.bytecode.proxy0；common causes of this problem include using a final class or a non-visible class
如果把服务消费reference的配置改为饥饿加载init=“true”，则启动不报错。
是什么原因导致
Pls. provide [GitHub address] to reproduce this issue.
### Expected Result
What do you expected from the above steps？
### Actual Result
What actually happens?

>如果没记错的话，servlet默认不属于spring容器的bean， 所以你这个注解是不被扫描的。
可以将这个servlet使用spring的方式 ServletRegistrationBean 来把这个servlet注册到spring容器里

这个问题跟dubbo关系不大，servlet 注入 spring bean 请参考 https://github.com/kexianjun/dubbo-test/blob/master/dubbo-issue-3827/issue-3827-comsumer/src/main/java/issue/test/servlet/WorkServlet.java

[#770]跟这个问题类似，差别在于没有使用注解的方式，通过<dubbo:reference >方式消费服务，并通过@Autowired的方式注入到servlet中

跟我的问题有点差异。我的是非注解方式，且如果通过配置饥饿加载可以注入。非饥饿加载Spring代理报无法继承final类无法进行字节码增强

使用lazy的得到的结果是你的接口单独被代理，而不是dubbo出来的proxy，这意味着你二次代理的对象不在是org.apache.dubbo.common.bytecode.proxy0。之后在你真正调用方法的时候才会引用到你的dubboproxy
