gateway网关动态刷新路由 Failed to bind properties under '' to org.springframework.cloud.gateway.filter.

Question

gateway网关动态刷新路由 Failed to bind properties under '' to org.springframework.cloud.gateway.filter.factory.AbstractNameValueGatewayFilterFactory$NameValueConfig

正式环境网关隔一段时间（一般是一天时间，短则半天）就会报动态刷新路的异常信息，导致线上出现请求网关超时，重启之后网关正常：
