应用级泛化调用 go client 调用 java service 调不通 [tag router] invokers from previous router is empty

[tuoxiebushuijiao]

1、go clinet 相关代码如下：
tripleRefConf := newRefConf("com.example.doubbo.dubbo.api.DemoService", tpconst.TRIPLE)
func newRefConf(iface, protocol string) config.ReferenceConfig {
registryConfig := &config.RegistryConfig{
Timeout: "3s",
Protocol: "nacos",
Address: "127.0.0.1:33366",
RegistryType: "service",
}
metadataConf := &config.MetadataReportConfig{
Protocol: "nacos",
Address: "127.0.0.1:33366",
}
refConf := config.ReferenceConfig{
InterfaceName: iface,
Cluster: "failover",
RegistryIDs: []string{"nacos"},
Protocol: protocol,
Generic: "true",
}

rootConfig := config.NewRootConfigBuilder().
	AddRegistry("nacos", registryConfig).
	  SetMetadataReport(metadataConf).
	Build()
if err := config.Load(config.WithRootConfig(rootConfig)); err != nil {
	panic(err)
}
_ = refConf.Init(rootConfig)
refConf.GenericLoad(appName)
return refConf

}
2、java springboot 配置文件如下：
dubbo:
application:
logger: slf4j
name: DoubboApplication
metadataServiceProtocol: dubbo
registry:
address: nacos://127.0.0.1:33366
registerMode: instance
protocol:
name: tri
port: 50052
serialization: hessian2
provider:
serialization: hessian2
metadata-report:
address: nacos://127.0.0.1:33366

3、调用结果信息如下：
