Spring Cloud Gateway Key Features
Spring Cloud Gateway is an API gateway tool developed using Spring WebFlux and based on Spring Framework 5. It provides the following functionalities:
- Routing forwarding: Based on the path and conditions of the request, it is possible to forward the request to different service instances.
- Filter: You can add custom filtering logic during the request and response processing, such as authentication, request logging, etc.
- Load balancing: supports integrated load balancers, which can forward requests to different service instances based on load balancing policies.
- Circuit breaker mechanism: Supports integrated fuses, which automatically stop forwarding requests to a service instance when it fails or exceeds a set threshold, preventing service cascades.
- Flow control mechanism: Supports integrated flow limiters that can restrict requests based on set flow control strategies to prevent the service from being overwhelmed by too many requests.
- Path rewriting: allows for modifying the request path to address inconsistencies in path mapping between services.
- 集成Spring Cloud服务发现：可以与Spring Cloud的服务注册与发现组件进行集成，自动发现并路由到可用的服务实例。
- Monitoring and statistics: You can monitor and collect statistics on the performance and status of the gateway by integrating Spring Cloud’s monitoring and statistics components.
- High availability: supports high availability deployment of multiple Gateway instances, with requests being forwarded to available Gateway instances through a load balancer.
It is important to note that Spring Cloud Gateway is not a complete API gateway solution, but rather provides a basic framework and tools for developers to customize and further develop according to their own needs.
