### 环境搭建 ###

#### 服务环境搭建 ####

1.  Maven依赖配置

建立Maven项目结构如下：

--springcloud-alibaba-gateway
    |----springcloud-provider
    |----springcloud-gateway
    复制代码

*  父项目**springcloud-alibaba-gateway**的POM依赖

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>

1.  接口代码编写

应用服务测试接口编写, 该接口将通过gateway服务进行负载均衡

package com.amano.springcloudalibabaproduct.controller;
