SpringCloud成长笔记（四）zuul路由网关

一、环境

最早我们使用springboot+nginx+vue，基本就能达到负载均衡和路由转发。现在我们使用springcloud的zuul实现。

二、配置

pom.xml，前面几章新建module的时候以为springcloud最新版本jar包依赖有问题，现在看来是nexus的私服没有把相关的依赖下载下来的问题，换成aliyun的maven仓库就好了。

启动类增加EnableZuulProxy注解

package com.mhm;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableZuulProxy
@EnableEurekaClient
public class ZuulApplication {

	public static void main(String[] args) {
		SpringApplication.run(ZuulApplication.class, args);
	}
}
