我已经使用 jetty 通过 SSL 启用了 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 jetty 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
最佳答案
它终于适用于 jetty 9.3.0!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 配置的内容:
<build>
<finalName>${project.artifactId}</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
<verbose>true</verbose>
</configuration>
</plugin>
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>${jetty-version}</version>
<configuration>
<webAppSourceDirectory>${project.build.directory}/${project.name}</webAppSourceDirectory>
<systemProperties>

</configuration>
<dependencies>

</dependency>
</dependencies>
</plugin>
</plugins>
</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工件版本: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>
关于jetty - 使用 maven-jetty-plugin 启用 HTTP2，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29389690/
