@hoheart

应该兼容。我们试了2.6.8，是兼容的。

@iluoxuan

兼容老版本的dubbo admin么...

hoheart

@hoheart

不兼容

iluoxuan

@iluoxuan

你们生产怎么升级的？

hoheart

@hoheart

我们没怎么用admin。一个服务一个服务，滚动升级啊

@peachyy

不能用内部API 用了就不兼容了哈

Dubbo 2.5.3 能消费 2.6x高版本的服务吗

hoheart

@hoheart

可以

@Dark0Forest

dubbo 消费端有办法获取是哪个生产端调用的么

@itfredmoon

有人吗。。

qunxing

@xingguangsixian

dubbuo现在2.7.1稳定吗？能用到生产环境吗?

dubbo的http协议加api网关大家都怎么搞的，是结合spring boot的，用spring cloud gateway的网关吗？

kuailerensheng

@kuailerensheng

请问一下dubbo（版本2.6.2）发布的webservice用cxf怎么调用？我用 cxf生成的客户端调用会报错：Fault string, and possibly fault code, not set 这个问题怎么解决？

qunxing

@xingguangsixian

dubbo-spring-boot中，dubbo的service怎么调用dao的接口，现在dubbo管理的service和spring容器管理的dao不能相互调用，service无法注入dao，有解决方案没？

@wecloud2008

Spring boot 2怎么使用dubbo

JianNie

@niejian

@xingguangsixian 2.7.1有问题，尽量用2.7.2

风险提示：升级到2.7.1版本后，注册中心（多数是zookeeper）在某些特殊场景下会出现重复URL地址数据无法删除，导致消费方拿到的是失效地址，从而导致调用失败的问题，2.7.2版本里面会修复此问题，预计6月初发布。详细原因请参考#4213。

telnet invoke命令调用时，如何设置RpcContext中的attachment信息？

tang199010

@tang199010

RpcContext.getContext().setAttachment(TraceIdUtil.TRACE_ID, TraceIdUtil.getTraceId());
这个设置对象之后，在服务端读取一直获取到上一个对象缓存值，不知道为什么！！
invocation.getAttachments().put(TraceIdUtil.TRACE_ID, TraceIdUtil.getTraceId());
最后这样就不会出现了，每次拿到都是最新的值

Dubbo Spring Boot 对我来说还是很好使用的，但一直有一个问题困恼我，就是分布式事物的处理，经过我半月研究，提出了自己解决分布式事物的一种处理方式，请各位大神有需要可以使用看看，有任何问题提出来可以一起讨论完善；
我这个分布式事物解决方法优势：零配置、零耦合、零依赖、且高效率、应用简单。具体引用说明链接：https://blog.csdn.net/WOSHITANGWENLE/article/details/89245056

hi. is this the same room as apache dubbo?

if so, in brave we are trying to release apache dubbo and in travis CI, tests that pass on OS/x fail Which looks like a bug

openzipkin/brave#1003

Caused by: org.apache.dubbo.common.bytecode.NoSuchMethodException: Not found method "sayHello" in class org.apache.dubbo.rpc.service.GenericService.

for some reason it is looking for the RPC method on the wrong type. "sayHello" would be on the interface type, not in the generic one

I tried to look through changelog for 2.7.4 and it was too much to notice. Also, I can't even find how javaassist ends up in the jar, because there is no reference to javaassist artifact in the entire repo.
