原来dubbo 还支持 golang 呢，可以用相互调用，相爱了。使用java 做服务端，golang做客户端

1，关于 dubbo-go

https://dubbo.apache.org/zh-cn/

官方提供了 dubbo-go 的代码
但是并不支持试 Hessian(X)
https://github.com/dubbo/dubbo-go
具体说明：

  • 1 Transport: HTTP(√)
  • 2 Codec: JsonRPC(√), Hessian(X)
  • 3 Service discovery：Service Register(√), Service Watch(√)
  • 4 Registry: ZooKeeper(√), Etcd(X), Redis(X)
  • 5 Strategy: Failover(√), Failfast(√)
  • 6 Load Balance: Random(√), RoundRobin(√)
  • 7 Role: Consumer(√), Provider(X)

2，栗子

本来想自己写一个例子。
没有想到官方都做好了。只要调用就可以了。

https://github.com/dubbo/dubbo-go/tree/master/examples
但是没有跑通，不过没有关系，发现另外一个项目
也是这个作者写的。不知道为啥没有迁移过来。
https://github.com/AlexStocks/dubbogo-examples
https://github.com/AlexStocks/dubbogo
这个项目：
两个项目需要合到一起次才能跑起来。
dubbo-go 里面跑 java ，dubbogo-examples 里面跑 golang
java：

package com.ikurento.user;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Provider {

    /**
     * To get ipv6 address to work, add
     * System.setProperty("java.net.preferIPv6Addresses", "true");
     * before running your application.
     */
    public static void main(String[] args) throws Exception {
        String[] confs = new String[]{"META-INF/spring/dubbo.provider.xml"};
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(confs);
        context.start();
        System.out.println("################## start ##################");
        System.in.read(); // press any key to exit
    }
}

4，总结

以前有很多项目都是java写的，业务逻辑是用dubbo做的服务。
这部分是不可能重写了。但是要是使用golang开发新项目。需要用到 dubbo服务。
支持的协议 hessian2 ，这样写的程序就可以相互调用了。
超级兴奋。同时问了下作者， dubbo-go 再过1 - 2 月也能完善了。
同时也可以使用 golang 做server服务，让java 程序去做client 调用。
非常非常帮的。
