本章基于SpringCloud Ribbon负载均衡配置案例说明

步骤一：新建maven module端口8547

<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.gcxzflgl.spring</groupId>
			<artifactId>springCloud-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>

步骤二：在resources下新、建application.yml

server: 
  port: 8547
 
spring: 
  application:
    name: springCloud-zuul-gateway
 
eureka: 
  client: 
    service-url: 
      defaultZone: http://eureka7001:7001/eureka,http://eureka7002:7002/eureka,http://eureka7003:7003/eureka  
  instance:
    instance-id: gateway
    prefer-ip-address: true 
 
 
 
info:
  app.name: springCloud
  company.name: www.gcxzflgl.com
  build.artifactId: $project.artifactId$
  build.version: $project.version$

步骤三：hosts映射 

127.0.0.1 gateway

步骤四：编写主类，测试

package com.gcxzflgl.springCloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableZuulProxy
public class Zuul_8547_StartSpringCloudApp
{
	public static void main(String[] args)
	{
		SpringApplication.run(Zuul_8547_StartSpringCloudApp.class, args);
	}
}

添加代理方式访问，修改application.yml

zuul: 
  routes: 
    mydept.serviceId: microservicecloud-dept
    mydept.path: /mydept/**

通过服务名称获取服务应用

虚拟服务名访问

原微服务名忽略掉访问。修改application.yml

zuul: 
  ignored-services: "*"
  routes: 
    mydept.serviceId: microservicecloud-dept
    mydept.path: /mydept/**

设置统一公共前缀，修改application.yml

zuul: 
  prefix: /gcxzflgl
  ignored-services: "*"
  routes: 
    mydept.serviceId: microservicecloud-dept
    mydept.path: /mydept/**
