gateway网关实现路由基于nacos注册中心

首先你需要启动nacos服务，才能开始下面的效果

这里10010为网关端口

nacos你需要

当服务都启动后，你应该看到如下服务

好了，下面开始上代码了

首先是网关部分

下面是网关的pom文件

@EnableDiscoveryClient
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

　　代码完毕，需要注意的gateway并没有rabbin了，所以需要引入loadbalancer
