无法加载容器提供程序类:org.glassfish.tyrus.container.grizzly.GrizzlyEng

Question

im 新到WebSockets . 为了开始学习，我遵循了本教程. 并简单地复制了ClientEndpoint和ServerEndpoint，并使用tyrus部署了服务器。

但是当我尝试运行服务器时，它会抛出此错误：

Failed to load container provider class: org.glassfish.tyrus.container.grizzly.GrizzlyEngine

这是部署代码(我已经注释了我得到错误的行(：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import org.glassfish.tyrus.server.Server;
public class WebSocketServer {
    public static void main(String[] args) {
        runServer();
    }
    public static void runServer() {
        Server server = new Server("localhost", 8000, "/websockets", WordgameServerEndpoint.class);
        try {
            server.start(); //i get the error on this line
            BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
            System.out.print("Please press a key to stop the server.");
            reader.readLine();
        } catch (Exception e) {
            System.out.println(e.getMessage());
        } finally {
            server.stop();
        }
    }
}

这是服务器代码：

import java.io.IOException;
import java.util.logging.Logger;
import javax.websocket.CloseReason;
import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.CloseReason.CloseCodes;
import javax.websocket.server.ServerEndpoint;
@ServerEndpoint(value = "/game")
public class WordgameServerEndpoint {
    private Logger logger = Logger.getLogger(this.getClass().getName());
    @OnOpen
    public void onOpen(Session session) {
        logger.info("Connected ... " + session.getId());
    }
    @OnMessage
    public String onMessage(String message, Session session) {
        switch (message) {
            case "quit":
                try {
                    session.close(new CloseReason(CloseCodes.NORMAL_CLOSURE, "Game ended"));
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
                break;
        }
        return message;
    }
    @OnClose
    public void onClose(Session session, CloseReason closeReason) {
        logger.info(String.format("Session %s closed because of %s", session.getId(), closeReason));
    }
}

我将不胜感激任何帮助:)

这

似乎是一个依赖问题，

如果您是 Maven 用户：

<dependencies>
    <dependency>
        <groupId>javax.websocket</groupId>
        <artifactId>javax.websocket-api</artifactId>
        <version>1.0</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.tyrus</groupId>
        <artifactId>tyrus-server</artifactId>
        <version>1.1</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.tyrus</groupId>
        <artifactId>tyrus-client</artifactId>
        <version>1.1</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.tyrus</groupId>
        <artifactId>tyrus-container-grizzly</artifactId>
        <version>1.1</version>
    </dependency>
    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>2.5</version>
    </dependency>
</dependencies>

或加载以下罐子：

• 灰熊框架-2.3.3.jar
• 灰熊-http-2.3.3.jar
• 灰熊-http-服务器-2.3.3.jar
• 灰熊-RCM-2.3.3.jar
• javax.websocket-api-1.0.jar
• 泰勒斯客户端-1.1.jar
• 泰勒斯集装箱灰熊-1.1.jar
• 泰勒斯核心-1.1.jar
• 泰勒斯服务器-1.1.jar
• 泰勒斯-斯皮-1.1.jar
• Tyrus-websocket-core-1.1.jar

请记住客户端和服务器实现的这些依赖项。
