spring-cloud-starter-gateway-mvc的网关实现

一 概括

最近，我也一直在使用SpringCloudGateway开发我们自己的网关产品。根据我对官网文档： docs.spring.io/spring-cloud-gateway/reference/spring-cloud-gateway-server-mvc.html 的理解，内容如下：

SpringCloudGateway的默认底层依赖项是SpringWebflux。我们知道Spring Webflux是异步和响应式编程，并且编程范式是使用流范式编写的；

那么SpringCloudGateway支持同步网关吗？官方支持，官方网站提供了相应的解决方案，即将默认的底层Webflux切换到SpringMVC以支持同步；

相当于SpringCloudGateway为您提供了两种网关路由的底层实现，一种是对应于SpringWebflux的异步实现，另一种是与SpringMVC对应的同步实现。

Above is all the code

5 Request Results GET http://localhost:9098/demo?ceshi=ceshi HTTP/1.1 200 date: Fri, 15 Dec 2023 09:23:37 GMT Content-Type: application/json Transfer-Encoding: chunked Keep-Alive: timeout=60 Connection: keep-alive { "code": 0, "data": "ceshi" } Response file saved. > 2023-12-15T172337.200.json Response code: 200; Time: 19ms (19 ms); Content length: 25 bytes (25 B)

The destination service address of the route is in SimpleGateway, you can change it to your own service
