什么是Zuul?

Zuul包含了两个主要的功能：

路由

和

过滤

路由功能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中获得其他服务的消息，使得以后的访问微服务都是通过Zuul跳转后获得。

详细步骤

1.新建springcloud-zuul模块，并导入依赖

<dependencies>
    <!--导入zuul依赖-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-zuul</artifactId>
        <version>1.4.6.RELEASE</version>
    </dependency>
    <!--Hystrix依赖-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-hystrix</artifactId>
        <version>1.4.6.RELEASE</version>
    </dependency>
    <!--dashboard依赖-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-hystrix-dashboar</artifactId>
        <version>1.4.6.RELEASE</version>
    </dependency>
    <!--Ribbon-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-ribbon</artifactId>
        <version>1.4.6.RELEASE</version>
    </dependency>
    <!--Eureka-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka</artifactId>
        <version>1.4.6.RELEASE</version>
    </dependency>
    <!--实体类+web-->
    <dependency>
        <groupId>com.haust</groupId>
        <artifactId>springcloud-api</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!--热部署-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>
</dependencies>

2.配置application.yml

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

  instance:
    instance-id: zuul9527.com
    prefer-ip-address: true

#info
info:
  app.name: com.diviner
  company.name: oj.diivner.com

zuul:
  routes:
    mydept.serviceid: springcloud-provider-dept
    mydept.path: /mydept/**
  ignored-services: springcloud-provider-dept #不能在使用原路径访问  "*" 隐藏全部服务
  prefix: /diviner # 设置公共前缀

3.编写主启动类

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableZuulProxy //
public class ZuulApplication_9527 {
    public static void main(String[] args) {
        SpringApplication.run(ZuulApplication_9527.class,args);
    }

}

4.启动7001、hystrix_8001、zuul_9527、80进行测试
