Spring Cloud Zuul RateLimit对Zuul APIGateway进行限流

1、POM依赖

# Spring Cloud Zuul RateLimit
<dependency>
    <groupId>com.marcosbarbero.cloud</groupId>
    <artifactId>spring-cloud-zuul-ratelimit</artifactId>
    <version>2.2.7.RELEASE</version>
</dependency>

# Redis
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2、YAML配置

spring:
  application:
    name: springcloud-zuul
  profiles:
    active: ${ENVIRONMENT:pro}
  redis:
    host: 10.10.253.16
    port: 6379
server:
  port: 8125
zuul:
  prefix: /api # 给网关路由添加前缀
  ignored-services: springboot-produce, springboot-consume # 关闭默认路由配置
  add-host-header: true # 设置为true重定向是会添加host请求头
  routes:
    springboot-produce:
      path: /produce/**
    springboot-consume:
      path: /consume/**
  ratelimit:
    enabled: true
    repository: REDIS
    key-prefix: zrl-
    behind-proxy: true
    add-response-headers: false
    deny-request:
      response-status-code: 404
      origins:
        - boer.xyz
    default-policy-list:
      - limit: 20
        refresh-interval: 30
        type:
          - origin
          - url
    policy-list:
      springboot-produce:
        - limit: 5
          refresh-interval: 60
          type:
            - url=/hello

3、Test验证

# 对/hello接口每分钟限制5次访问
curl -is http://10.10.10.56:8125/api/produce/hello
# 对其他接口无限制
curl -is http://10.10.10.56:8125/api/produce/
