[GitHub] [dubbo] songxiaosheng opened a new issue, #11184: Dubbo3调用配置了提供者path属性的服务提供者出现找不到提供者的报错
songxiaosheng opened a new issue, #11184:
URL: https://github.com/apache/dubbo/issues/11184
<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy -->
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 3.1.0 -> 2.7.5.x
* Operating System version: linux,windows
* Java version: 1.8
### Steps to reproduce this issue
1. 配置了path属性的服务提供者启动 dubbo老版本
2. 消费者启动订阅服务失败 dubbo3.1.0这个版本
Pls. provide [GitHub address] to reproduce this issue.
### Expected Behavior
<!-- What do you expect from the above steps？-->
感觉是dubbo3的服务消费者没有兼容path这个配置与dubbo低版本表现得行为不一样，导致序列化检查时候失败了
### Actual Behavior
<!-- What actually happens? -->

> path 这个属性是给 rest 协议使用的，对于 dubbo 协议如果以前是兼容的话得看下差异点在哪
dubbo2缓存的key是path和版本号组成的
dubbo3缓存的key是接口和版本号组成的
如果dubbo3配置了path dubbo2调用dubbo3的时候 dubbo3内部就会找不到这个提供者导致调用失败 估计兼容比较麻烦 可以看下CodeSupport这个类型的checkSerialzation方法

https://github.com/apache/dubbo/issues/6138 这个问题修复了之后 dubbo协议 提供者拿到的低版本消费者和高版本消费者的第二个字段path是不一样的 ，高版本只会取interface 低版本如果存在path则会取path 稍等先等我确认下安全校验的代码的版本
