有没有人在 netty (http/2) 中使用 spring-webflux?
Spring Documentation说:
You can enable HTTP/2 support in your Spring Boot application with the
server.http2.enabled
configuration property. This support depends on the chosen web server and the application environment, since that protocol is not supported out-of-the-box by JDK8. Spring Boot does not support h2c, the cleartext version of the HTTP/2 protocol. So you must configure SSL first.

server.http2.enabled
不适合我。我正在使用:
请看一下我的配置:
HTTPS 也可以。
但是协议(protocol)还是一样的(http/1.1)
.
这是 ALPN 的问题吗?我应该将我的应用程序升级到 JDK10 吗?
我将不胜感激任何建议。谢谢。
最佳答案
简而言之,它在 Spring Framework 5.1 中得到支持。使用 JDK1.8,您需要使用原生库来支持 ALPN。
Spring 文档中引用的声明具有误导性。
Spring HTTP/2 wiki 页面 ( https://github.com/spring-projects/spring-framework/wiki/HTTP-2-support ) 有更多最新信息:
Reactor Netty
As of Spring Framework 5.1 (Reactor Netty 0.8), this server supports as well HTTP/2. JDK9+ deployments will support that protocol without specific infrastructure changes.
For JDK 8 environments, or for optimal runtime performance, this server also supports HTTP/2 with native libraries. To enable that, your application needs to have an additional dependency.
这是对我有用的 pom.xml:
