晚上好,

我有一个简单的 websocket 应用程序。如果我使用 asadmin 命令或我的 IDE 将它部署到独立 glassfish 服务器,它运行良好。当我使用 glassfish - embedded时,一切似乎都很好(没有错误消息),但我在应该服务 websocket 的端点处得到 404。

WebSocket connection to 'ws://localhost:8080/test/websocket/zelitomasfds/efdsdfsdf' failed: Error during WebSocket handshake: Unexpected response code: 404

这是代码,应该很简单

/* Imports skipped */    

@ServerEndpoint("/websocket/{email}/{type}")
public class SimpleHOTPWebSocket {
    @OnMessage
    public void onMessage(String message, Session session)
            throws IOException, InterruptedException {

        System.out.println("Received: " + message);
    }

    @OnOpen
    public void onOpen(Session session, 
                       EndpointConfig c,
                       @PathParam("email") String email,
                       @PathParam("type") String type) {
        System.out.println("Client " + email + " connected as a " + type);
    }

    @OnClose
    public void onClose(Session session) {
        System.out.println("Connection closed");
    }
}

这是我的 pom.xml:

我也尝试过使用 webapp-runner 和 jetty 运行它,所以问题一定出在我的代码或 pom.xml 中。

我正在启动服务器mvn clean install embedded-glassfish:run

如果您想查看源代码或尝试使用 war 文件,请随时在此处下载(war)请,任何人都可以看到我做错了什么吗?

感谢您的帮助,我已经为此苦苦挣扎了 10 多个小时。

也很抱歉我的英语不好

你在标题中提到 glassfish-embedded,但你也提到你尝试过使用 jetty 和 webapp-runner,所以我知道在“嵌入式​​”模式下你不关心你使用哪个。

因此,我下载了您的资源,进行了尝试,重现了问题(相同的行为),然后...从 POM 中删除了几乎所有内容,并使用 Jetty 从头开始​​添加所需的位,因为我更熟悉它,它只需要中央 Maven 存储库(未添加存储库)。总体来说要简单很多。

您的代码只需要一个依赖项javax.websocket-api。其余的都是配置jetty:run(我配置了上下文路径“/test”以符合您的期望,默认为“/”)。

简而言之:用上面的替换你的POM,执行mvn jetty:run,然后访问http://localhost:8080/test
