soul网关第三步-演示apache-dubbo服务
soul源码地址：https://github.com/dromara/soul
第三天，演示dubbo服务。
之前简单了解过dubbo，但都是基于照葫芦画瓢的状态，将功能配置上，按顺序启动服务进行调用。对其实现原理等，并不是很了解。希望借助这次学习，能够对dubbo的原理有更深入的学习和了解。
我们知道Dubbo是一种分布式服务框架，技术架构如图所示：
在soul网关中，服务提供者和消费者分别是谁呢？
当然服务的消费者是soul-admin，soul-examples-dubbo模块是服务的提供者。
我们打开网关界面dubbo的插件开关：
由于在项目中zookeeper为我们的注册中心，我们要配置单机的zookeeper服务。
配置方法连接可参考：https://www.iteye.com/blog/coolxing-1871009
启动zookeeper服务后，我们启动其中的soulBootstrapApplication服务。
此时控制台显示如下状态表示服务正常启动，我们成功注册了服务：

页面刷新dubbo插件模块：
页面请求注册接口：
服务端日志展示：
2021-01-17 00:20:12.400 INFO 5166 --- [work-threads-16] o.d.soul.plugin.base.AbstractSoulPlugin : dubbo selector success match , selector name :/dubbo

我们可以看到项目中有两个dubbo服务端，一个是alibaba，另一个是apache。这两个有什么区别呢？
留个思考题。
