websocket实现自动派单

WebSocket 是一种在单个 TCP 连接上进行全双工通信的协议，它常用于实现即时通信、在线聊天等功能。使用 WebSocket 可以实现实时更新任务状态、自动派单等功能。以下是一个简单的实现示例：

1. 创建 WebSocket 服务器类 WebSocketServer，监听客户端连接并处理客户端请求。

public class WebSocketServer extends WebSocketServerAdapter {
    private List<WebSocket> connections = new ArrayList<>();
    private List<Task> tasks = new ArrayList<>();
    private List<Handler> handlers = new ArrayList<>();

    public WebSocketServer(int port) {
        super(port);
    }

    @Override
    public void onWebSocketConnect(WebSocket conn) {
        super.onWebSocketConnect(conn);
        connections.add(conn);
        System.out.println("WebSocket connected: " + conn.getRemoteSocketAddress());
    }

    @Override
    public void onWebSocketClose(WebSocket conn, int code, String reason, boolean remote) {
        super.onWebSocketClose(conn, code, reason, remote);
        connections.remove(conn);
        System.out.println("WebSocket closed: " + conn.getRemoteSocketAddress());
    }

    @Override
    public void onWebSocketMessage(WebSocket conn, String message) {
        super.onWebSocketMessage(conn, message);
        System.out.println("WebSocket message: " + message);
        // 处理客户端请求，例如添加任务、添加处理人员等
        // 省略具体实现
    }

    public void assignTasks() {
        for (Task task : tasks) {
            Handler handler = findHandler(task);
            if (handler != null) {
                System.out.println("Assign task " + task.getName() + " to handler " + handler.getName());
                task.setStatus(1); // 标记任务已完成
                sendTaskStatus(task); // 发送任务状态更新给客户端
            } else {
                System.out.println("No available handler for task " + task.getName());
            }
        }
    }

    private Handler findHandler(Task task) {
        for (Handler handler : handlers) {
            if (handler.getTaskTypes().contains(task.getName()) && isHandlerAvailable(handler)) {
                return handler;
            }
        }
        return null;
    }

    private boolean isHandlerAvailable(Handler handler) {
        // 判断处理人员是否可用，例如是否已经处理了最大任务数等
        return true;
    }

    private void sendTaskStatus(Task task) {
        JSONObject json = new JSONObject();
        json.put("type", "taskStatus");
        json.put("taskId", task.getId());
        json.put("status", task.getStatus());
        String message = json.toString();
        for (WebSocket conn : connections) {
            conn.send(message);
        }
    }
}

2. 创建客户端类 WebSocketClient，连接 WebSocket 服务器并发送消息。

public class WebSocketClient extends WebSocketClientAdapter {
    private WebSocketClient client;

    public WebSocketClient(String serverUrl) throws URISyntaxException {
        client = new WebSocketClient(new URI(serverUrl));
    }

    @Override
    public void onWebSocketConnect(WebSocket websocket) {
        super.onWebSocketConnect(websocket);
        System.out.println("WebSocket connected: " + websocket.getRemoteSocketAddress());
    }

    @Override
    public void onWebSocketClose(WebSocket websocket, int code, String reason) {
        super.onWebSocketClose(websocket, code, reason);
        System.out.println("WebSocket closed: " + websocket.getRemoteSocketAddress());
    }

    @Override
    public void onWebSocketMessage(WebSocket websocket, String message) {
        super.onWebSocketMessage(websocket, message);
        System.out.println("WebSocket message: " + message);
        // 处理服务器返回的消息，例如更新任务状态等
        // 省略具体实现
    }

    public void send(String message) {
        client.send(message);
    }

    public void connect() {
        client.connect();
    }

    public void close() {
        client.close();
    }
}

3. 在主函数中创建 WebSocketServer 和 WebSocketClient，启动 WebSocket 服务器并连接 WebSocket 客户端，实现自动派单功能。

public static void main(String[] args) throws URISyntaxException {
    WebSocketServer server = new WebSocketServer(8888);
    server.start();

    WebSocketClient client = new WebSocketClient("ws://localhost:8888/");
    client.connect();

    // 添加任务和处理人员
    // 省略具体实现

    server.assignTasks(); // 自动派单

    client.close();
    server.stop();
}

以上是一个简单的 WebSocket 实现自动派单的示例，具体实现可根据实际需求进行调整。
