廖师兄好！向你请教一个问题

我编写了一个自定义工厂类 RequestTimeGatewayFilterFactory ，在.yml中配置为 ‘- RequestTime=true’，但是报了一个错误 “java.lang.IllegalArgumentException: Unable to find GatewayFilterFactory with name RequestTime”，是我忽略了什么吗？Finchley.SR2版本，求解答！

spring:
  profiles:
    active: request_time_route
spring:
  cloud:
    gateway:
      routes:
        - id: request_time_route
          uri: https://www.baidu.com/
          filters:
            - RequestTime=true
          predicates:
            - After=2019-03-20T17:42:47.789-07:00[Asia/Shanghai]
  profiles: request_time_route
