docker微服务部署之：三，搭建Zuul微服务项目

docker微服务部署之：二、搭建文章微服务项目

一、新增demo_eureka模块,并编写代码

右键demo_parent->new->Module->Maven,选择Module SK为jdk8->ArtifactId:demo_zuul

1.修改pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>demo_parent</artifactId>
        <groupId>com.demo</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>demo_zuul</artifactId>

    <dependencies>
　　　　 <!-- 服务网关依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
        </dependency>
        <!-- eureka客服端依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
    </dependencies>
</project>

2.在resources目录下新增application.yml文件

server:
  port: 8888
spring:
  application:
    name: demo-zuul
zuul:
  routes: # 配置路由
    app:  # 路由名称，这是一个标识作用，只要是[a-z]可随意，没有什么影响
      path: /myarticle/* #匹配以/myarticle路径开头的所有路径
      serviceId: demo-article #只要符合path规则，则转发到demo-article微服务
eureka:
  client:
    fetch-registry: true
    register-with-eureka: true
    service-url:
      defaultZone: http://127.0.0.1.181:7000/eureka #在IDEA中运行时使用127.0.0.1，部署发布时，请修改为虚拟机宿主机的ip地址
  instance:
    prefer-ip-address: true

3.新建com.demo.zuul包，并在该包下新建启动类ZuulApplication

package com.demo.zuul;

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;

/**
 * 微服务网关
 */
@SpringBootApplication
// 标注启动zuul网关代理
@EnableZuulProxy
// 标注eureka客户端
@EnableEurekaClient
public class ZuulApplication {
    public static void main(String[] args) {
        SpringApplication.run(ZuulApplication.class, args);
    }
}

4.运行ZuulApplication启动类

刷新eureka界面，可以看到有一个名为DEMO-ZUUL的服务已经注册上来了

5.测试zuul网关代理是否成功

docker微服务部署之：四、安装docker、docker中安装mysql和jdk1.8、手动构建镜像、部署项目
