# 使用zuul实现服务路由请求分发 #

## 概述 ##

通过整合zuul实现了服务路由设置，请求分发的功能。

## 实现步骤分析 ##

### 引入相关依赖依赖 ###

<dependencies>
        <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>
    </dependencies>

### 创建application.yml文件 ###

spring:
      application:
        name: microservice-service-zuul
    
    server:
      port: 7000
    
    eureka:
      client:
        service-url: 
          # eureka Server端地址
          defaultZone: http://peer1:8761/eureka/,http://peer2:8762/eureka/
    
    zuul:
      # 忽略单个服务实例：
      # ignored-services: microservice-service-provider
      # "*"表示忽略所有微服务，所有请求均不能通过服务的应用名称来访问
      # 例如：http://localhost:7000/tyrone/microservice-service-provider/provider/request/info是访问不通的
      # 如果不声明此属性，上述请求是可以访问成功的
      ignored-services: "*"
      # 指定路由前缀,所有请求均需要带此前缀
      prefix: /tyrone
      routes:
        provider: # 相当于服务路由模块名称，如果与service-id相同，那么service-id可以不用声明
          service-id: microservice-service-provider # 表示微服务的应用名称，需要与Eureka Server中保持一致
          path: /api/** # 以/api开始的请求均可以映射到service-id代表的微服务应用上

### 创建springcloud-zuul启动类 ###

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
    
    @EnableZuulProxy    // 开启zuul代理
    @SpringBootApplication
    public class Application { 
        public static void main(String[] args) throws Exception {
            SpringApplication.run(Application.class, args);
        }
    
    }

### 测试 ###

本项目的测试需要启动`springcloud-eureka-server-peer`和`springcloud-service-provider-high-available`这个工程，其次启动本项目。  
通过访问路由访问服务提供者服务：  
[http://localhost:7000/tyrone/api/provider/request/info][http_localhost_7000_tyrone_api_provider_request_info]  
结果如下图：  
![这里写图片描述][70]  
通过服务提供者的链接直接请求：[http://localhost:8000/provider/request/info][http_localhost_8000_provider_request_info]  
结果如下图：  
![这里写图片描述][70 1]  
两者结果本质是一致的。
