Spring Cloud配置zuul路由网关

1、pom.xml

        <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>

2、application.yml

server:
  port: 9004
spring:
  application:
    name: spring-cloud-zuul

#注册中心指向start    
eureka:
  instance:
    instance-id: spring-cloud-zuul
    appname: ${spring.application.name}
  client:
    service-url:
      defaultZone: http://pre1:8001/eureka/,http://pre2:8002/eureka/
#注册中心指向end

zuul:
  routes:
    api-a:
      path: /spring-cloud-common/**
      serviceId: spring-cloud-common
    api-b:
      path: /b/**
      serviceId: spring-cloud-consumer

3、启动类

@SpringBootApplication
@EnableZuulProxy
@EnableEurekaClient
@EnableDiscoveryClient
public class ZuulApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZuulApplication.class, args);
    }

}

关键点：

根据path中的路径匹配，然后通过服务名调用相应的服务，
