Environment

  • Server: Java-server, dubbo version v3.0.14
  • Client: Dubbo-go, v3.1.1
  • Protocol: Dubbo
  • Registry: Nacos, v2.1.2

Issue description

我参考这个官网学习java-server和go-client互通。https://cn.dubbo.apache.org/zh-cn/overview/mannual/golang-sdk/tutorial/develop/interflow/call_java/

java侧：org/xxx/dao/entity/DataSource.java部分代码如下： package org.xxx.dao.entity; ... import java.io.Serializable; import java.util.Date;

public class DataSource implements Serializable { private int id; private int userId; private String userName; private String name; private String note; private DbType type; private String connectionParams; private Date createTime; private Date updateTime; private String fromType;

public DataSource() {
}

}

org.xxx.api.service.DataSourceService.java部分代码如下： package org.xxx.api.service; ... import org.xxx.dao.entity.DataSource; ... import java.net.UnknownHostException; import java.util.List; import java.util.Map;

public interface DataSourceService { ... Map<String, Object> queryDataSource(int id); ... }

代码中也有DataSourceService的实现类DataSourceServiceImpl.java，代码不做赘述 dubbo-provider.xml的配置如下： <dubbo:application name="${dubbo.applicationName}" > </dubbo:application> <dubbo:config-center address="${dubbo.nacos.registryAddress}" namespace="${dubbo.nacos.namespace}"/> <dubbo:metadata-report address="${dubbo.nacos.registryAddress}"> <dubbo:parameter key="namespace" value="${dubbo.nacos.namespace}"/> </dubbo:metadata-report> <dubbo:registry id="nacos" address="${dubbo.nacos.registryAddress}" username="${dubbo.nacos.username}" password="${dubbo.nacos.password}"> <dubbo:parameter key="namespace" value="${dubbo.nacos.namespace}"/> </dubbo:registry> <dubbo:protocol id="dubbo" name="dubbo" host="10.1.5.175" port="20010"/>

    <dubbo:service ref="dataSourceService" delay="5000" interface="org.xxx.api.service.DataSourceService" timeout="3000" registry="nacos" protocol="dubbo"/>
<bean id="dataSourceService" class="org.xxx.api.service.impl.DataSourceServiceImpl"/>

Dubbo-Go端： model/models.go package model

import ( "context" "fmt" "time" )

type DataSource struct { Id int hessian:"id" UserId int hessian:"userId" UserName string hessian:"userName" Name string hessian:"name" Note string hessian:"note" Type string hessian:"type" // Mapped from Java enum ConnectionParams string hessian:"connectionParams" CreateTime time.Time hessian:"createTime" UpdateTime time.Time hessian:"updateTime" FromType string hessian:"fromType" }

// JavaClassName returns the fully qualified class name of the Java class. func (d *DataSource) JavaClassName() string { return "org.xxx.dao.entity.DataSource" }

func (d DataSource) String() string { return fmt.Sprintf("DataSource{ID: %d, UserID: %d, UserName: %s, Name: %s, Note: %s, Type: %s, ConnectionParams: %s, CreateTime: %v, UpdateTime: %v, FromType: %s}", d.Id, d.UserId, d.UserName, d.Name, d.Note, d.Type, d.ConnectionParams, d.CreateTime, d.UpdateTime, d.FromType)

}

// DataSourceService is the interface for the DataSource service type DataSourceService struct { QueryDataSource func(ctx context.Context, id int) (*DataSource, error) dubbo:"queryDataSource" }

main.go代码如下： package main

import ( "Dubbo-Go/model" "context" "dubbo.apache.org/dubbo-go/v3/config" _ "dubbo.apache.org/dubbo-go/v3/imports" // 导入dubbo-go需要的所有默认包 hessian "github.com/apache/dubbo-go-hessian2" "github.com/dubbogo/gost/log/logger" ) var ( dataSourceService = &model.DataSourceService{} ) func main() { hessian.RegisterPOJO(&model.DataSource{}) config.SetConsumerService(dataSourceService) err := config.Load() if err != nil { panic(err) } logger.Infof("\n\ntest") test()

}

func test() { logger.Infof("开始测试调用 queryDataSource 方法")

id := 1
logger.Infof("即将调用 queryDataSource, ID: %d", id)
dataSources1, err := dataSourceService.QueryDataSource(context.TODO(), id)
if err != nil {
	logger.Errorf("调用 queryDataSource 失败: %v", err)
}
logger.Infof("response result: %v", dataSources1)

}

dubbogo.yml文件如下： dubbo: registries: nacos: protocol: nacos timeout: 60s address: nacos://10.1.5.230:8848 namespace: dubbogo username: nacos password: nacos protocols: "dubbo": name: "dubbo" port: 20010 address: 10.1.5.175 consumer: references: DataSourceService: protocol: dubbo interface: org.xxx.api.service.DataSourceService retries: 6 timeout: 6000 logger: zap-config: level: info

具体情况如上：这个报错查阅相关资料后，能力有限，依旧是无法解决java.lang.IllegalArgumentException: Service not found:org.xxx.api.service.DataSourceService, queryDataSource
