broadcast

介绍​

广播是通信方式之一，广播也称推送。常用于主动给一个、多个或全服的用户发送数据。比如：

  1. 一个 : 给指定的在线用户发送一些奖励。
  2. 多个 : 给在同一个房间内的用户广播一些数据，如某一个用户射击子弹，把这子弹的数据广播给房间内的其他用户。
  3. 全服 : 给全服的所有在线用户广播消息，如广播公告、即将停服维护等。
tip

通信模型的请求参数支持 int、long、bool、String、Object、 List<Integer>、List<Long>、List<Boolean>、List<String>、List<YourClass>

  • BroadcastAction

广播给指定单个用户​

广播给指定单个用户， api 名字以 broadcastUser 打头。

@ActionController(BroadcastCmd.cmd)
public class BroadcastAction {
    AtomicInteger inc = new AtomicInteger();

    @ActionMethod(triggerBroadcastUser)
    private void triggerBroadcastUser(long userId) {
        var communication = CommunicationKit.getCommunication();

        // ---------- object ----------
        BookMessage dataObject = new BookMessage();
        dataObject.authorName = "ionet";
        dataObject.bookName = "book-" + inc.getAndIncrement();
        communication.broadcastUser(userId, BroadcastCmd.broadcastUserObject, dataObject);
    }
}

广播给指定多个用户​

广播给指定多个用户， api 名字以 broadcastUsers 打头。

@ActionController(BroadcastCmd.cmd)
public class BroadcastAction {
    AtomicInteger inc = new AtomicInteger();

    @ActionMethod(triggerBroadcastUsers)
    private void triggerBroadcastUsers(List<Long> userIdList) {
        var communication = CommunicationKit.getCommunication();

        // ---------- object ----------
        BookMessage dataObject = new BookMessage();
        dataObject.authorName = "ionet";
        dataObject.bookName = "book-" + inc.getAndIncrement();
        communication.broadcastUsers(userIdList, BroadcastCmd.broadcastUsersObject, dataObject);
    }
}

广播给所有人​

广播给所有人， api 名字以 broadcastMulticast 打头。

@ActionController(BroadcastCmd.cmd)
public class BroadcastAction {
    AtomicInteger inc = new AtomicInteger();

    @ActionMethod(triggerBroadcastMulticast)
    private void triggerBroadcastMulticast() {
        var communication = CommunicationKit.getCommunication();

        // ---------- object ----------
        BookMessage dataObject = new BookMessage();
        dataObject.authorName = "ionet";
        dataObject.bookName = "book-" + inc.getAndIncrement();
        communication.broadcastMulticast(BroadcastCmd.broadcastMulticastObject, dataObject);
    }
}

广播的路由建议​

使用广播起始标记递增的方式来指定广播路由，这种方式可以让我们不需要关注具体的路由值。

public interface BroadcastCmd {
    int cmd = CmdModule.broadcastCmd;
    // ---------- broadcastUser ----------
    int triggerBroadcastUser = 1;
    ...

    AtomicInteger inc = new AtomicInteger(10);
    private static CmdInfo ofBroadcastCmd() {
        return CmdInfo.of(cmd, inc.getAndIncrement());
    }

    // ---------- broadcastUser ----------
    CmdInfo broadcastUserEmpty = ofBroadcastCmd();
    CmdInfo broadcastUserInt = ofBroadcastCmd();
    CmdInfo broadcastUserBool = ofBroadcastCmd();
    CmdInfo broadcastUserLong = ofBroadcastCmd();
}

// test
@ActionController(BroadcastCmd.cmd)
public class BroadcastAction {
    AtomicInteger inc = new AtomicInteger();

    @ActionMethod(triggerBroadcastUser)
    private void triggerBroadcastUser(long userId) {
        var communication = CommunicationKit.getCommunication();

        // ---------- empty ----------
        communication.broadcastUser(userId, BroadcastCmd.broadcastUserEmpty);

        // ---------- int ----------
        int dataInt = inc.getAndIncrement();
        communication.broadcastUser(userId, BroadcastCmd.broadcastUserInt, dataInt);

        // ---------- boolean ----------
        boolean dataBool = inc.getAndIncrement() % 2 == 0;
        communication.broadcastUser(userId, BroadcastCmd.broadcastUserBool, dataBool);
    }
}

开启广播日志​

warning

该功能为企业级功能

开启广播的日志后，可以获取广播的代码定位。

@ActionController(BroadcastCmd.cmd)
public class BroadcastAction {
    AtomicInteger inc = new AtomicInteger();

    @ActionMethod(triggerBroadcastUser)
    private void triggerBroadcastUser(long userId) {
        // ---------- object ----------
        BookMessage dataObject = new BookMessage();
        dataObject.authorName = "ionet";
        dataObject.bookName = "book-" + inc.getAndIncrement();
        communication.broadcastUser(userId, BroadcastCmd.broadcastUserObject, dataObject);

        // ---------- string ----------
        String dataString = "ionet-" + inc.getAndIncrement();
        communication.broadcastUser(userId, BroadcastCmd.broadcastUserString, dataString);
    }
}

点击控制台打印的 BroadcastAction.java:45 就可以跳转到对应的广播业务代码。
