上篇我們介紹了zuul是什么？大家已經有些了解，廢話不多說我們就開始實際代碼演示下zuul如何配置

一，新建一個路由網關的微服務 microservicecloud-zuul-gateway-9527

二，pom文件添加zuul相關依賴

pom文件的相關依賴

<?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>microservicecloud</artifactId><groupId>com.atguigu.springcloud</groupId><version>1.0-SNAPSHOT</version></parent><modelVersion>4.0.0</modelVersion><artifactId>microservicecloud-zuul-gateway-9527</artifactId><dependencies><!-- zuul路由網關 --><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-zuul</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-eureka</artifactId></dependency><!-- actuator監控 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><!-- hystrix容錯 --><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-hystrix</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-config</artifactId></dependency><!-- 日常標配 --><dependency><groupId>com.atguigu.springcloud</groupId><artifactId>microservicecloud-api</artifactId><version>${project.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jetty</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId></dependency><!-- 熱部署插件 --><dependency><groupId>org.springframework</groupId><artifactId>springloaded</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId></dependency></dependencies></project>

三，修改微服務網關啟動類

啟動類加了一個注解應該都看見了吧！這個注解@EnableZuulProxy就是開啟Zuul路由網關，顧名思義就是一個Proxy代理

?

四，修改yml文件

server: port: 9527spring: application:name: microservicecloud-zuul-gatewayeureka: client: service-url: defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka,http://eureka7003.com:7003/eureka instance:instance-id: gateway-9527.comprefer-ip-address: true info:app.name: atguigu-microcloudcompany.name: www.atguigu.combuild.artifactId: $project.artifactId$build.version: $project.version$

五，系統hosts域名映射文件修改?

hosts文件位置C:\Windows\System32\drivers\etc

hosts文件添加127.0.0.1 myzuul.com

?

到這里我們就已經修改完了，就啟動測試看一下

?

?

不使用路由網關正常訪問http://localhost:8001/dept/get/1

使用路由網關正常訪問http://myzuul.com:9527/microservicecloud-dept/dept/get/2
