# Dubbo结合Gateway实现微服务网关 #

## 前言 ##

最近，我发布了`Dubbo Demo`项目以及`Gateway`网关的博客，于是奇思妙想到能不能将两者结合起来呢？首先我们可以在`Dubbo`的官网中看了开发者文档，它推荐使用的网关只有三种`Kong`、`Dubbo Proxy`以及`Zuul`，而`Gateway`被认为是`Zuul`的替代品，所以从理论上是完全可行，所以来吧，展示！

Nacos安装以及其使用可参考我的博客：[Nacos服务治理中心和配置中心][Nacos]

Gateway安装及使用可参考我的博客：[微服务网关-Gateway][-Gateway]
