Jersey Grizzly 宁静的服务器在 Linux 上抛出一个奇怪的 URISyntaxException答案

【问题标题】：Jersey Grizzly restful server throws a strange URISyntaxException on LinuxJersey Grizzly 宁静的服务器在 Linux 上抛出一个奇怪的 URISyntaxException
【发布时间】：2012-05-16 06:52:17
【问题描述】：

我创建了一个在 Win7 上运行良好的 Jersey-Grizzy-Server。但是在 Linux 上启动后，我会得到一个奇怪的、总是重复的异常

java.lang.IllegalArgumentException: java.net.URISyntaxException: Expected hostname at index 8: https://:443/

，即使没有调用服务器。休息服务一直在工作。有人知道为什么会出现这个异常，或者如何开始调试 grizzly2 Httpserver？

Server Start 是这样实现的（简化）：

boolean https = true;
int port = 9960;
URI baseURI = UriBuilder.fromUri("http" + (https ? "s" : "") + "://0.0.0.0/").port(port).build();

//Jersey Service Config
final ResourceConfig rc = new UriExtensionsConfig(GcardApplication.getConfigPackages());

// create Grizzly Container
final HttpHandler handler = ContainerFactory.createContainer(HttpHandler.class, rc);

//do the ssl Config
SLEngineConfigurator ssl = configSSL(https);

HttpServer server = GrizzlyServerFactory.createHttpServer(baseURI, handler, https, ssl);

【问题讨论】：

你是否在你的 Linux 发行版中配置了环回地址（可能是 /etc/hosts）？
我们已经为 /etc/hosts 配置了 127.0.0.1 localhost
可以让 Jersey Logger 工作。在那里我可以看到我的服务器被调用的位置。看起来反向代理正在调用端口：9960 而不是 443。

标签： java rest https glassfish jersey

【解决方案1】：

问题的根源是 ReversProxys Healthcheck 的配置，它具有以下发送字符串

GET / HTTP/1.1\r\nHost: \r\nConnection: close\r\n\r\n

我们必须将获取请求更正为

GET https://servername:9960/ HTTP/1.1\r\nHost: originalservername\r\nConnection: close\r\n\r\n

【解决方案2】：

https://:443/ 不是有效的 URL - 没有主机名。

从您的代码中，我看到您调用了UriBuilder.fromUri("https://0.0.0.0/")

"0.0.0.0" 在这里真的是一个有效值吗？

检查命令hostname和domainname的输出；它们应该返回有用的值（domainname 不是那么重要，但如果它有一些有用的值会更好）。

如何确定自己的IP地址另见这个答案：How to get the ip of the computer on linux through Java?

[编辑]您可能在代码中查看了错误的位置。在URISyntaxException的构造函数中设置断点，找出损坏的URI是从哪里来的。

【讨论】：

泽西工厂从 URI u 内部分配它： final String host = (u.getHost() == null) ？ NetworkListener.DEFAULT_NETWORK_HOST : u.getHost();使用常量 String DEFAULT_NETWORK_HOST = "0.0.0.0" 但同样的问题是 2 个网络侦听器 1 用于 localhost，另一个用于服务器 IP。
啊。您发布的代码用于设置 Jersy。但正如您在日志中看到的那样，该部分确实有效（端口 = 9660）。您需要检查为 SSL 访问创建 URL 的代码（端口为 443 的代码）。
服务器运行。端口 443 上没有网络侦听器。此请求来自哪里？网络统计-apl | grep 443 unix 2 [ACC] STREAM LISTENING 27443 - 私有/scache
我正在努力从安全部门打开一个端口以进行调试。
正如我所说：在构造函数中创建一个断点，你就会知道。任何试图建立连接的人最终都必须通过这部分代码，否则您将不会在日志中看到异常:-)
