启动 SpdyServer 并测试
最后更新于:2022-04-01 02:36:42
请注意,当您使用 Jetty NPN 库需要提供它的位置通过 bootclasspath 的 JVM 参数。这一步是必需的,这样才能访问 SslEngine接口。(`-Xbootclasspath` 选项允许您覆盖标准 JDK 附带的实现类)。
下面的清单显示了特殊的参数(`-Xbootclasspath`)使用。
Listing 12.7 SpdyServer implementation
~~~
java -Xbootclasspath/p:<path_to_npn_boot_jar> ....
~~~
最简单的方式是使用 Maven 项目管理:
Listing 12.8 Compile and start SpdyServer with Maven
~~~
$ mvn clean package exec:exec -Pchapter12-SpdyServer

可以用2个浏览器进行测试,一个支持 SPDY 一个不支持,这里我们用的是 Google Chrome (支持 SPDY) 和 Safari。
浏览器访问 [https://127.0.0.1:9999,会显示](https://127.0.0.1:9999%EF%BC%8C%E4%BC%9A%E6%98%BE%E7%A4%BA/) SpdyRequestHandler 的处理结果,如下图

Google Chrome 的一个很好的功能是可以统计数据,可以很好的看到连接情况。 在浏览器中访问 chrome://net-internals/#spdy 可以看到详细的统计数据

若不支持 SPDY ,比如我们用 Safari 浏览器访问 [https://127.0.0.1:9999](https://127.0.0.1:9999/) ,则响应将会用 HttpRequestHandler 处理
