3. 注解方式
Dubbo 控制台 环境搭建
本篇将介绍Spring boot zookeeper Dubbo 简易环境的搭建以及使用首先准备好一台虚拟机。
1. 在虚拟机上安装JDK8及以上版本可以参考我的另一篇博客 https://www.cnblogs.com/chen1-kerr/p/6907280.html
2. 在虚拟机上安装zookeeper。可以是单机也可以是集群。可以参考我的文件
单机 zookeeper 单机环境搭建三_chen_yao_kerr的博客-CSDN博客
集群 zookeeper集群二_zookeeper集群相互发现_chen_yao_kerr的博客-CSDN博客
3. 新建2个spring boot工程一个是Server端一个是client端并且引入zookeeper 和 dubbo依赖的jar包。

/project我本次使用的虚拟机IP是 192.168.0.105。 因此需要到这台虚拟机服务器上启动zookeeper 抽象出接口 Dubbo的3种使用方式
1. XML配置的方式一般用于Spring MVC工程
服务端Server
服务端需要去实现这个接口因为这个实现类要提供具体的业务处理逻辑 服务端的xml配置

/beans 、客户端Consumer
?xml version1.0 encodingUTF-8?beans xmlnshttp://www.springframework.org/schema/beansxmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexmlns:contexthttp://www.springframework.org/schema/contextxmlns:dubbohttp://code.alibabatech.com/schema/dubboxsi:schemaLocationhttp://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.1.xsdhttp://code.alibabatech.com/schema/dubbohttp://code.alibabatech.com/schema/dubbo/dubbo.xsddubbo:application namebusi-client /dubbo:registry addresszookeeper://192.168.0.105:2181 /dubbo:consumer /dubbo:reference idorderService interfacecom.enjoy.service.OrderService //beans 启动Server 启动客户端 2. 配置文件的方式 spring boot工程
首先在Server端定义配置文件 开放一个业务类 服务端加载配置 在Consumer端定义配置文件 定义一个类这个类要从远程服务器上拿到需要使用的实例 消费端调用 3. 注解方式
这种方式其实和第2种方式基本一致唯一的不同就是少了个配置文件这个配置文件多了些注入的类
服务端代码

}其实具体怎么用可根据实际情况进行选择。如果是Spring MVC工程选第一种方式比较好。如果是Spring boot工程我个人倾向于选择第二种方式也就是注解配置文件的方式。 Dubbo 控制台
dubbo-admin 的地址为 mirrors / apache / dubbo-admin · GitCode
但是我使用命令拉下来总是少文件所有我直接下载的zip包解压。 修改配置 编译并启动 能打开页面能够登录即可 上方介绍了集中服务端启动的方式选择任意一种方式启动服务端代码如果在控制台能够发现即可
