二、SpringcloudGatewayApplication.java

package com.urthink.upfs.springcloudgateway;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* http://localhost:8081/demo/test1
* http://localhost:8080/app1/demo/test1
* http://localhost:8082/demo/test1
* http://localhost:8080/app2/demo/test1
*/
@SpringBootApplication
public class SpringcloudGatewayApplication {
public static void main(String[] args) {
SpringApplication.run(SpringcloudGatewayApplication.class, args);
}
}


三、application.yml

server:
port: 8080
eureka:
instance:
prefer-ip-address: true
#Eureka客户端向服务端发送心跳的时间间隔，单位为秒（客户端告诉服务端自己会按照该规则），默认30
lease-renewal-interval-in-seconds: 10
#Eureka服务端在收到最后一次心跳之后等待的时间上限，单位为秒，超过则剔除（客户端告诉服务端按照此规则等待自己），默认90
lease-expiration-duration-in-seconds: 12
client:
registry-fetch-interval-seconds: 10 #eureka client刷新本地缓存时间，默认30
serviceUrl:
defaultZone: http://localhost:8761/eureka/
spring:
application:
name: gateway
cloud:
gateway:
routes:
#netty 路由过滤器，http或https开头
- id: app1-route
uri: http://localhost:8081
predicates:
- Path=/app1/**
filters:
#转发请求时去掉1级前缀
- StripPrefix=1
#LoadBalancerClient负载均衡过滤器（整合eureka注册中心），lb开头
- id: app2-route
