使用 maven-jetty-plugin 启用 HTTP2

【中文标题】使用 maven-jetty-plugin 启用 HTTP2【英文标题】：Enable HTTP2 with maven-jetty-plugin 【发布时间】：2015-06-06 00:50:27 【问题描述】：我已经使用码头启用了基于 SSL 的 HTTP/2 连接器。当我尝试连接浏览器时，出现“ERR_SSL_PROTOCOL_ERROR”错误。如果我切换到 HTTP/1.1 连接器，一切正常。
这是我的码头配置文件：

我正在使用 jetty-server、http2-server 和 jetty-alpn-server 工件版本 9.3.0.M1，是否需要添加任何其他依赖项？我正在使用JDK7。
谢谢
【问题讨论】：
【参考方案1】：终于可以在 jetty 9.3.0 上使用了！我们需要确保 ALPN 配置良好并且我们使用 JDK8。
这是我为 maven-jetty-plugin 配置的：
<build>
<finalName>$project.artifactId</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>

</configuration>
<dependencies>

</build>
<properties>
<jetty-version>9.3.0.M2</jetty-version>
<alpn-version>8.1.0.v20141016</alpn-version>
</properties>
根据JDK版本选择ALPN神器版本：http://eclipse.org/jetty/documentation/current/alpn-chapter.html
我还在 HTTP2ServerConnectionFactory 之前添加了这两个 ConnectioFactory
<Call name="addConnectionFactory">
<Arg>
<New class="org.eclipse.jetty.server.SslConnectionFactory">
<Arg name="next">alpn</Arg>
<Arg name="sslContextFactory"><Ref refid="sslContextFactory"/></Arg>
</New>
</Arg>
</Call>
<Call name="addConnectionFactory">
<Arg>
<New id="alpn" class="org.eclipse.jetty.alpn.server.ALPNServerConnectionFactory">
<Arg type="String">
<Property name="alpn.protocols" default="" />
</Arg>
<Set name="defaultProtocol">
<Property name="alpn.defaultProtocol" />
</Set>
</New>
</Arg>
</Call>
