zuul路由网关
1.是什么
Zuul包含了对请求的路由和过滤两个最主要的功能:
其中路由功能负责将外部请求转发到具体的微服务实例上,是实现外部访问统一入口的基础而过滤器功能则负责对请求的处理过程进行干预,是实现请求校验、服务聚合等功能的基础.
Zuul和Eureka进行整合,将Zuul自身注册为Eureka服务治理下的应用,同时从Eureka中获得其他微服务的消息,也即以后的访问微服务都是通过Zuul跳转后获得。
注意:Zuul服务最终还是会注册进Eureka
提供=代理+路由+过滤三大功能
2.能干嘛
路由、过滤
官网资料:https://github.com/Netflix/zuul/wiki/Getting-Started
3.实验代码-路由基本配置
1.新建Module模块microservicecloud-zuul-gateway-9527
2.修改Pom
<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"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.atguigu.springcloud</groupId> <artifactId>microservicecloud</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>microservicecloud-zuul-gateway-9527</artifactId> <dependencies> <!-- zuul路由网关 --> <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监控 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <!-- hystrix容错--> <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> <!-- 日常标配 --> <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> <!-- 热部署插件 --> <dependency> <groupId>org.springframework</groupId> <artifactId>springloaded</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> </dependency> </dependencies> </project>
3.修改ym
server: port: 9527 spring: application: name: microservicecloud-zuul-gateway eureka: client: service-url: defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka,http://eureka7003.com:7003/eureka instance: instance-id: gateway-9527.com prefer-ip-address: true info: app.name: atguigu-microcloud company.name: www.atguigu.com build.artifactId: $project.artifactId$ build.version: $project.version$
4.hosts修改127.0.0.1 myzuul.com
5.主启动类
package com.atguigu.springcloud; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.zuul.EnableZuulProxy; @SpringBootApplication @EnableZuulProxy public class Zuul_9527_StartSpringCloudApp { public static void main(String[] args) { SpringApplication.run(Zuul_9527_StartSpringCloudApp.class, args); } }
7.启动
三个eureka集群
一个服务提供类microservicecloud-provider-dept-8001
一个路由
8.测试
不用路由:http://localhost:8001/dept/get/2
启用路由:http://myzuul.com:9527/microservicecloud-dept/dept/get/2
4.实验代码-路由访问映射规则
1.工程microservicecloud-zuul-gateway-9527
2.代理名称
yml
before http://myzuul.com:9527/microservicecloud-dept/dept/get/2 zuul: routes: mydept.serviceId: microservicecloud-dept mydept.path: /mydept/** after http://myzuul.com:9527/mydept/dept/get/1
此时问题
路由访问OK:http://myzuul.com:9527/mydept/dept/get/1
原路径访问OK:http://myzuul.com:9527/microservicecloud-dept/dept/get/2
3.原真实服务名忽略:
yml
zuul: ignored-services: microservicecloud-dept routes: mydept.serviceId: microservicecloud-dept mydept.path: /mydept/**
单个具体,多个可以用"*"
zuul: ignored-services: "*" routes: mydept.serviceId: microservicecloud-dept mydept.path: /mydept/**
5.设置统一公共前缀
YML
zuul: prefix: /atguigu ignored-services: "*" routes: mydept.serviceId: microservicecloud-dept mydept.path: /mydept/**
http://myzuul.com:9527/atguigu/mydept/dept/get/1
最后yml
server: port: 9527 spring: application: name: microservicecloud-zuul-gateway zuul: prefix: /atguigu ignored-services: "*" routes: mydept.serviceId: microservicecloud-dept mydept.path: /mydept/** eureka: client: service-url: defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka,http://eureka7003.com:7003/eureka instance: instance-id: gateway-9527.com prefer-ip-address: true info: app.name: atguigu-microcloud company.name: www.atguigu.com build.artifactId: $project.artifactId$ build.version: $project.version$
