java语音聊天室怎样实现啊?
实现java语音聊天室的方法很简单,要么自己从零研发,要么直接使用别人的成品,意思是找网上的第三方,他们自己有研发产品的。建议考虑ZEGO即构科技,他们的语聊房SDK很好用的,提供低延迟和低成本的方案供选择,在保障语音质量的前提下,码率最低可到8kbps,可以试试。

给你一个简单的实现吧,注意一定要先运行MyServer.java

add(jsp,"Center");
bt=new JButton("SEND");
bt.addActionListener(this);
pan.add(tf);
pan.add(bt);
add(pan,"South");
this.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
setTitle("THE CLIENT");
setSize(400,300);
setVisible(true);
try{

我做java的简易聊天室,已经可以群聊和私聊,如何把创建房间加进去,且只能同一个房间里才能群聊和私聊?
我说下思路:
1、客户端创建房间时给每个房间分配惟一的一个房间ID,房间是公开的,每个连接的客户端都可以看到,房间属性,比如密码,比如黑名单,房间保存在Server内存当中,如果你使用了集群,建议存储到分布式缓存当中(Redis是最好的选择,其次是memcached),当创建完成后,将房间信息发送给所有客户端。新客户端连接进来时,客户端要主动从服务端拉取房间信息。建议采用服务端主动通知(房间增减,服务端主动通知给所有客户端)和客户端定时轮询(客户端起个定时任务,每隔一定时间主动向服务端拉取房间列表)的方式来保证房间列表的动态更新。
2、当客户端选择加入房间时,如果设置有加入条件,比如密码,那就提示客户端输入,如果是其他条件就判断加入客户端是否符合这个条件。服务端保存房间同客户端的关联关系(可以设计成一对多,也就是一个客户端只能在一个房间聊天,也可以设计成多对多,一个客户端可以同时加入多个房间聊天,主要看设计),并将这个消息通知给这个房间所有的客户端列表“欢迎***进入房间”(消息的发送者为系统,房间ID这个房间的ID,接收人无,表示是这个房间的公开消息,消息内容即:欢迎***进入房间。)
3、把聊天内容当成消息的话,那消息应该有这样的属性,发送人,房间ID(如果没有房间ID就当成系统公告消息,在所有房间显示),接收人(如果没有指定接收人,则是公开消息,如果有接收人,就是私聊消息,只能在同一个房间私聊,那在发消息的时候要判断下接收客户端的是否在这个房间列表当中)。
4、再来说消息路由设置,当客户端发送消息时,根据房间ID,找到这个这个房间内所有的客户端列表,如果没有指定接收人,那消息就推送给这个房间关联的所有客户端,如果指定有接收人,接收人不在这个房间,直接提示“***已经离开”,如果还在就把消息推送给这个指定的客户端。
5、房间的管理:踢人,把这个客户端从房间同客户端关联关系解除,并在房间显示消息“***被踢出房间”等等
