dubbo配置支持多协议，不能在service指定其中某一种协议--附详细错误提示

[fuhao715]

Originally posted by @beiwei30 in #2695 (comment)

Environment

Dubbo version: 2.6.2
Operating System version: mac
Java version: 1.8

配置如下

protocols

protocol1:

name: dubbo
id: dubbo
status: server

protocol2:

id: rest
name: rest
status: server
server: tomcat

contextpath: api/swift/v1
extension: com.alibaba.dubbo.rpc.protocol.rest.support.LoggingFilter

##服务注释

@service(
version = "${demo.service.version}",
application = "${dubbo.application.id}",
registry = "${dubbo.registry.id}",
protocol = "dubbo"
)
public class DefaultDemoService implements DemoService{
……………………
}

问题： 无法指定服务的协议类型。

建议：
service注解标明协议类型，则是指定类型暴露，否则按照配置协议类型暴露

工程启动错误提示如下：

Seems like this has been support on branch 2.6.x.

I used dubbo 2.6.2. #2695 (comment) is my issues。
dubbo-2.6.3~5 Bugfixes not found this problem。

[carryxyh]

I mean that it has been fixed on the latest version of 2.6.x branch. Not all the version of 2.6.x.

I mean that it has been fixed on the latest version of 2.6.x branch.

2.6.4 is not the latest version of 2.6.x.
The latest version is 2.6.5-SNAPSHOT

But 2.6.5-SNAPSHOT is not a release version. U can reproduce this problem in source code.
