使用网关服务统一接入

spring:
  application:
    name: mall-gateway
  cloud:
    gateway:
      routes:
        - id: third_party_route
          uri: lb://mall-third-party
          predicates:
            - Path=/api/third-party/**
          filters:
            - RewritePath=/api/third-party/(?<segment>.*),/$\\segment
