## 6、路由网关的设置 ##

**一、新建模块zuul**

**pom**

<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>
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
            
            <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>
            
            <dependency>
                <groupId>springcloud</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>
            
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>springloaded</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
            </dependency>
        </dependencies>

**application.yml**

server:
      port: 5555
    spring:
      application:
        name: zuul
    eureka:
      client:
        service-url:
          defaultZone: http://eureka7001.com:7001/eureka/
      instance:
        instance-id: zuul
        prefer-ip-address: true
    
    
    info:
      app.name: atguigu-microcloud
      company.name: yourcompanyname
      build.artifactId: $project.artifactId$
      build.version: $project.version$
    zuul:
      routes:
        h.serviceId: microservicecloud-dept
        h.path: /mydept/** prefix: /mist ignored-services: "*"

**必要说明**

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

**这一段的意思为 访问的微服务为microservicecloud-dept，并且需要在原来的  
访问路径前加/mydept ,在这个路径前面还得加前缀/mist  
最后一行为禁止原来的所有的访问路径生效。**

**主启动类**

package com.atguigu.springcloud;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
    
    @SpringBootApplication
    @EnableZuulProxy
    public class ZuulMainApplication { 
        public static void main(String[] args) { 
    
            SpringApplication.run(ZuulMainApplication.class,args);
        }
    }

**启动注册中心，服务提供者与zuul模块。访问并查看结果**  
[http://localhost:5555/mist/mydept/dept/list][http_localhost_5555_mist_mydept_dept_list] 可以得到结果

[http://localhost:5555/dept/list][http_localhost_5555_dept_list] 则无法返回值

即为上述解释的那个，禁止原来所有的访问地址。 否则，上面两个都可以返回正确的值

**后续：待续…**

[http_localhost_5555_mist_mydept_dept_list]: http://localhost:5555/mist/mydept/dept/list
[http_localhost_5555_dept_list]: http://localhost:5555/dept/list
