如何使用ALPN在SPDY上运行Jetty? [英] How to run Jetty with SPDY using ALPN?
问题描述
我使用Jetty和SPDY返回JDK8,我发现现在Jetty 9.2支持ALPN协议而不是NPN(请参阅我的问题
I have returned to JDK8 with Jetty and SPDY and I see that now Jetty 9.2 supports ALPN protocol instead of NPN (see my question How to run Jetty with SPDY on JDK8?). So I set bootclasspath
:
java -Xbootclasspath/p:c:/jars/alpn-boot/alpn-boot-8.0.0.v2014031 ...
但是现在我有了例外:
Exception in thread "xyz.server" java.lang.NoClassDefFoundError:
org/eclipse/jetty/npn/NextProtoNego$ServerProvider
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)

...
我使用java version "1.8.0_05"
和码头9.2.2.v20140723.
I use java version "1.8.0_05"
and jetty 9.2.2.v20140723.
我在WinXP上使用JDK 1.7和alpn-boot-7.0.0.v20140317.jar
遇到的相同错误,如果从-Xbootclasspath/p:c:/jars/npn-boot/npn-boot-1.1.7.v20140316.jar
The same error I got with JDK 1.7 and alpn-boot-7.0.0.v20140317.jar
on WinXP where I changed if from -Xbootclasspath/p:c:/jars/npn-boot/npn-boot-1.1.7.v20140316.jar
此执行将我的代码指向:
This execption points in my code into:
SSLconnector = new HTTPSPDYServerConnector(server, sslContextFactory);
看来,即使使用ALPN码头,也需要npn-boot中的类. 是错误还是我做错了什么?
It seems that even with ALPN jetty needs classes from npn-boot. Is it a bug or I have done something wrong?
推荐答案
HTTPSPDYServerConnector
尚未更新为ALPN,当前对NPN的使用进行了硬编码.
HTTPSPDYServerConnector
was not updated to ALPN and currently hardcodes usage of NPN.
要在SPDY上使用ALPN,您必须配置ServerConnector
来代替:
In order to use ALPN with SPDY you have to configure a ServerConnector
instead in this way:
SslContextFactory sslContextFactory = new SslContextFactory();
HttpConfiguration httpConfig = new HttpConfiguration();
SslConnectionFactory ssl = new SslConnectionFactory(sslContextFactory, "alpn");
ALPNServerConnectionFactory alpn = new ALPNServerConnectionFactory("spdy/3", "http/1.1");
alpn.setDefaultProtocol("http/1.1");
HTTPSPDYServerConnectionFactory spdy = new HTTPSPDYServerConnectionFactory(SPDY.V3, httpConfig);
HttpConnectionFactory http = new HttpConnectionFactory(httpConfig);
Server server = new Server();
ServerConnector connector = new ServerConnector(server, new ConnectionFactory[]{ssl, alpn, spdy, http});
server.start();
我将此跟踪为 https://bugs.eclipse.org/bugs/show_bug.cgi?id = 440756 .
最后,如果您不直接使用代码,而是将Jetty用作服务器并在其中部署Web应用程序,Jetty已经根据激活的模块正确配置了ALPN或NPN.
Finally, if you don't use the code directly, but use Jetty as a server and deploy webapps to it, Jetty already configures properly either ALPN or NPN depending on the modules that are activated.
