zuul服务网关

由于网关是通过注册中心找寻服务地址,所以需要注册到注册中心;

pom主要依赖如下:

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
        </dependency>

yml配置如下:

server:
  port: 7020
spring:
  application:
    name: springcloud-zuul
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:4020/eureka/

启动类:

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

启动eureka服务,然后再启动其他服务:访问eureka,观察注册信息:

 用zuul访问微服务(服务消费者)

 结果如下:

 如果不想暴露目标微服务的服务名,可以如下配置yml:

zuul:
  ignored-services:
  - open-feign-consumer #拒绝用目标微服务的名称来访问
  prefix: /main #访问路径前缀
  routes: #自定义路由配置
    employee:
      service-id: open-feign-consumer #目标微服务的名称
      path: /zuul-emp/** #新的访问路径
