I have a Spring Boot service that has registered some methods with ZooKeeper through Dubbo, and here is the configuration file for that service.
spring:
cloud:
zookeeper:
connect-string: 12.79.17.16:2186
discovery:
enabled: true
dubbo:
application:
name: dubbo-${spring.application.name}
qos-enable: false
metadata-type: remote
protocol:
name: dubbo
port: 20882
ssl-enabled: true
registry:
address: zookeeper://${spring.cloud.zookeeper.connect-string}
timeout: 25000
parameters:
blockUntilConnectedWait: 250
namespace: dms-local
provider:
filter: dubboTraceFilter,dmsUserProviderFilter
consumer:
filter: dubboTraceFilter,dmsUserConsumerFilter
timeout: 4000
check: false
metadata-report:
address: zookeeper://${spring.cloud.zookeeper.connect-string}
and now, I want to use dubbo-go as client to call these methods, here is my dubbo-go configuration.
dubbo:
registries:
demoZK:
protocol: zookeeper
timeout: 3s
address: 12.79.17.16:2186
username: dms
password: p-QXraCdR0y6FoX9D
consumer:
references:
SystemConfigService:
protocol: dubbo
interface: cn.ctyun.dms.console.api.dubbo.service.SystemConfigService
here is the client code with golang.
package main
import(
"context"
_ "dubbo.apache.org/dubbo-go/v3/imports"
"dubbo.apache.org/dubbo-go/v3/config"
"github.com/dubbogo/gost/log/logger"
)
var (
systemConfigService = &SystemConfigService{}
)
type SystemConfigService struct {
GetConfig func(ctx context.Context, req string) (*SystemConfigDTO, error) `dubbo:"getConfig"`
}
func init(){
config.SetConsumerService(systemConfigService)
}
func main(){
config.Load()
var i string = "hello"
config, err := systemConfigService.GetConfig(context.TODO(), i)
if err != nil {
panic(err)
}
logger.Infof("response result: %v", config)
}
but when I execute go run, the console gives me the following error:

I tried to modify every config, but I cannot call Java methods successfully, so what can I do for it?
