请看，通过排除tomcat starter并将jetty started添加到spring web配置中，以及添加jetty alpn conscrypt服务器、http2服务器依赖项，我能够在jetty服务器上使用JDK8在用户界面上启用HTTP/2支持

但是，在使用Netty server的Spring Cloud API网关端，我尝试了所有步骤，但没有弄清楚如何在Spring Cloud API网关启用HTTP/2，，我添加了Netty Tnative boringssl static作为依赖项，现在我遇到了这个错误

弹簧靴：2.1.9.1释放 春云：格林威治.SR3
Java版本：JDK-8

我通过将启动版本升级到2.2.5解决了这个问题。发布版本并将云版本升级到Hoxton.SR3

您一年前就解决了一个问题，已经检查了这个链接和类似链接，但没有任何东西对我有效。我正在使用Spring boot:2.1.9。发布Spring cloud:Greenwich.SR3 Java版本：JDK-8Did您尝试了fixed Reactor Netty版本，该版本>0.8.12.RELEASE，因为在上面的堆栈跟踪中，您仍然使用存在问题的版本？是的，然后它开始给出不同的依赖项错误
