学习笔记:微服务-5.spring zuul

spring cloud zuul 是网页api网关，就是说微服务有很多的服务，每个服务都有个自己的网址，采用zuul就可以从一个zuul网址对外服务，会自动跳转到设置的对应微服务上

1. 新建一个spring boot 项目 命名为Eureda-client-zuul

2.pom.xml

3. application.properties

server.port=8000
eureka.client.serviceUrl.defaultZone=http://admin:123@centos7:8888/eureka/
spring.application.name=Euredaclientzuul
zuul.routes.euredaclient1.path=/c1/**
zuul.routes.euredaclient1.serviceId=Euredaclient1
zuul.routes.springdemo.path=/sd/**
zuul.routes.springdemo.serviceId=SpringDemo

4. 启动类前加 @EnableZuulProxy

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

5.运行项目

http://centos7:8000/c1/hello    会自动跳转到Euredaclient1微服务地址即： http://centos7:8081/hello 

http://centos7:8000/sd/hello  会自动跳转到SpringDemo微服务地址即： http://centos7:8082/hello
