Spring Cloud Gateway :: Spring Cloud Gateway

This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency.

📝 核心概念

How to work

1. 客户端发起请求(Gateway Client)

2. Handler Mapping: 根据断言，转发请求

3. Web Handler: 处理请求(通过过滤器Filter)

4. Proxied Service：实际的服务

🤗 配置

在.yml中配置(建议)

编程式配置

断言

• After：在某个时间之后

• Before：在某个时间之前

• Between：在某个时间之间

• Cookie：cookie中包含某些参数

• Header：请求头包含某些值

• Host：请求域名

• Path：请求路径

• Method：请求方法

建议开启日志

过滤器

• AddRequestHeader：增加请求头

• AddRequestParameter：增加请求参数

• DedupeResponseHeader：去除请求头重复参数

• CircuitBreaker：熔断器，用于降级，需要添加依赖

• RequestRateLimiter：限流器，要使用redis辅助，内部使用了Token Bucket Algorithm

• StripPrefix：去除请求头部分内容

• Retry：请求重试器

• RequestSize：请求大小

• Default Filters：全局的过滤器，用于所有的路由
