报错截图：

网关配置文件中代码：

spring:
  application:
    name: cloud-gateway
  cloud:
    gateway:
      routes:
        - id: payment_route
          uri: http://localhost:8001
          predicates:
            - Path: /payment/get/**

        - id: payment_route2
          uri: http://localhost:8001
          predicates:
            - Path: /payment/lb/**

报错原因：

- Path后应该紧跟着路由信息，不要留空格
