Spring Cloud Gateway 扩展支持动态限流

之前分享过 一篇 《Spring Cloud Gateway 原生的接口限流该怎么玩》, 核心是依赖Spring Cloud Gateway 默认提供的限流过滤器来实现

原生RequestRateLimiter 的不足

• 配置方式

spring:
  cloud:
    gateway:
      routes:
      - id: requestratelimiter_route
        uri: lb://pigx-upms
        order: 10000
        predicates:
        - Path=/admin/**
        filters:
        - name: RequestRateLimiter
          args:
            redis-rate-limiter.replenishRate: 1  
            redis-rate-limiter.burstCapacity: 3
            key-resolver: "#{@remoteAddrKeyResolver}" #SPEL表达式去的对应的bean
        - StripPrefix=1

• RequestRateLimiterGatewayFilterFactory

public GatewayFilter apply(Config config) {
    KeyResolver resolver = getOrDefault(config.keyResolver, defaultKeyResolver);
    RateLimiter
