微服务zuul(七)

开始干，新建cloud-zuul-gateway-9527,pom文件如下

>yml文件

server: 
  port: 9527
 
spring: 
  application:
    name: cloud-zuul-gateway
 
eureka: 
  client: 
    service-url: 
      defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka,http://eureka7003.com:7003/eureka

  build.version: $project.version$

>启动类

	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);
		}
	}

>然后开启7001-3,cloud-provider-dept-8001,和当前9527 [http://localhost:7001/](http://localhost:7001/)  [http://localhost:8001/dept/get/2](http://localhost:8001/dept/get/2)  [http://localhost:9527/cloud-dept/dept/get/1](http://localhost:9527/cloud-dept/dept/get/1)  >这样就通过zuul路由访问到了微服务

既然要用zuul肯定会遇到路由多个微服务，还有名字统一，zuul自动给我们路由，怎么办？
修改yml文件，加入

zuul:
  #ignored-services: cloud-dept                             #原路径失效（单个）
  prefix: /tzy                                             #调用前路径
  ignored-services: "*"                                   #原路径失效（批处理）
  routes:
    mydept.serviceId: cloud-dept                          #访问cloud-dept这个微服务的全名
    mydept.path: /mydept/**                               #可以理解为别名

[http://localhost:9527/tzy/mydept/dept/get/1](http://localhost:9527/tzy/mydept/dept/get/1) 

补充，之前我们定义了

修改hosts文件

http://gateway-9527.com:9527/tzy/mydept/dept/get/1

成功了哦
