Java Jetty客户端可以'；t通过HTTP/2连接到Jetty服务器

java

Java Jetty客户端可以'；t通过HTTP/2连接到Jetty服务器,java,embedded-jetty,http2,jetty-9,Java,Embedded Jetty,Http2,Jetty 9,下面我使用的是“HTTPS/1.1”，意思是HTTPS超过HTTP1.1。下面的所有连接都是HTTPS，没有简单的HTTP 我的服务器在端口10443上以HTTPS/1.1的形式运行嵌入式Jetty，在端口10444上以HTTPS/2的形式运行嵌入式Jetty。两个端口都工作，它们之间没有其他区别。对HTTPS/1的回退也有效（使用chromium浏览器--disable-http2进行测试）。以下是整个客户端代码： public static void main(String[] args)

下面我使用的是“HTTPS/1.1”，意思是HTTPS超过HTTP1.1。下面的所有连接都是HTTPS，没有简单的HTTP

我的服务器在端口10443上以HTTPS/1.1的形式运行嵌入式Jetty，在端口10444上以HTTPS/2的形式运行嵌入式Jetty。两个端口都工作，它们之间没有其他区别。对HTTPS/1的回退也有效（使用chromium浏览器--disable-http2进行测试）。以下是整个客户端代码：

public static void main(String[] args) throws Exception {
    final HttpClient httpClient = new HttpClient(new SslContextFactory());
    httpClient.start();
    httpClient.GET(TEST_URL);
}
测试URL是使用thawte签名的证书的
localhost
，这是正确的，但对于
localhost
显然无效

我很惊讶HTTPS/1可以工作，因为curl拒绝使用它

curl: (51) SSL: certificate subject name (...) does not match target host name 'localhost'
我可能一直在愚弄全局java密钥库，这也许可以解释为什么它与Jetty一起工作。但是，使用Jetty的HTTPS/2不起作用，我得到的只是这两个神秘的堆栈跟踪：

知道发生了什么吗

更新
Jetty客户端也不与我们的生产站点合作（那里有有效的证书）。当使用chromium浏览器——disable-http2连接到我们的生产站点时，它显示HTTP/1头，但列协议中有h2。

对于Jetty的
HttpClient
要使用HTTP/2，您需要使用HTTP/2传输实例化它

正在开发对HTTP/2和HTTP/1之间自动切换的支持，请参阅

还要记住，要使HTTP/2在TLS上工作，还需要设置ALPN。 推荐的方法是使用内置支持ALPN的JDK 9，因此您需要类路径中的
jetty ALPN java client
工件，另请参见
