dubbo 2.7 与 dubbox 2.8.4 如何混合使用?

[HWliao]

公司历史项目几乎使用的都是dubbox2.8.4, 现在新的项目准备使用dubbo 2.7 请问dubbo2.7 能否直接兼容dubbox2.8.4 本人有尝试过通过dubbo-spring-boot-starter集成dubbo2.7 直接消费dubbox的提供的服务, 结果在调用时报错了, 跟踪了一下代码, 发现response 返回状态码40 BadRequest

使用的是zookeeper注册中心 生产者和消费者使用的协议都是protocol dubbo

You can try dubbo 2.6.5

使用dubbo 2.6.5 dubbo starter 0.2.1.release 调用dubbox2.8.4提供的服务依旧(消费者)报错

dubbox 生产者 序列化 改为hessian2, 可以通过dubbo2.7 调用
