Spring Cloud Alibaba GateWay’s routing assertion factory

Spring Cloud Gateway uses route matching as the most basic function. This function is accomplished through the routing assertion factory. Spring Cloud Gateway contains many built-in routing assertion factories. All these assertions can match different attributes of HTTP requests, and multiple routing assertion factories can be combined based on logic and status. 1. After routing […]
