配置文件

server:

#服务名
spring:
  application:
    name: gateway-service
  cloud:
    gateway:
      routes:
        - id:  consulserver
          # 重点！/info必须使用http进行转发，lb代表从注册中心获取服务
          uri: lb://consulserver
          predicates:
            # 重点！转发该路径！,/userapi/**,
            - Path=/consulserver/**
          # http://localhost:6601/userapi/user/users/2, 必须加上StripPrefix=1，否则访问服务时会带上userapi
          #而不是我们期望的去掉userapi，只保留**部分
          filters:
            - StripPrefix=1
      discovery:
        locator:
