配置 application.yml 配置台哦转访问的是8001服务

server:
  port: 9527
spring:
  application:
    name: cloud-gateway
  cloud:
    gateway:
      routes:
      - id: payment_routh #路由的ID，没有固定规则但要求唯一，建议配合服务名
        uri: http://localhost:8001   #匹配后提供服务的路由地址
        predicates:
          - Path=/payment/get/**   #断言,路径相匹配的进行路由

      - id: payment_routh2
        uri: http://localhost:8001
        predicates:
          - Path=/payment/lb/**   #断言,路径相匹配的进行路由


eureka:
  instance:
    hostname: cloud-gateway-service
  client:
    service-url:
      register-with-eureka: true
      fetch-registry: true
      defaultZone: http://eureka7001.com:7001/eureka

配置简单讲解 id就是路由唯一性 随便起个名字即可
