最近比較流行的http2協(xié)議，在spring boot中可以使用了，昨天看了spring boot 官方文檔?發(fā)現(xiàn)目前只有undertow和tomcat 服務(wù)器才支持而目前spring boot 集成的Tomcat 8.5.x 支持http2稍微麻煩點(diǎn)，需要用到?tomcat-native。啟動(dòng)的時(shí)候要加上?-Djava.library.path=/usr/local/opt/tomcat-native/lib? 不然會(huì)報(bào)錯(cuò)

ERROR 8787 --- [ main] o.a.coyote.http11.Http11NioProtocol : The upgrade handler [org.apache.coyote.http2.Http2Protocol] for [h2] only supports upgrade via ALPN but has been configured for the ["https-jsse-nio-8443"] connector that does not support ALPN.

這里我就拿undertow舉例，關(guān)鍵配置如下：

application.properties

server.port=8443server.ssl.key-store=classpath:test.dureshangmao.com.jksserver.ssl.enabled=trueserver.ssl.key-password=1063420481server.ssl.key-store-password=1063420481server.http2.enabled=true

pom.xml

然后寫(xiě)一個(gè)Controller,借助google瀏覽器的一個(gè)插件就可以檢測(cè)你搭建的http2是否成功了
