直接上代碼

System.out.println("===========publisher end=============");

}
package com.guo.client;
import org.zeromq.ZMQ;
import org.zeromq.ZMQ.Context;
import org.zeromq.ZMQ.Socket;

Socket socket = context.socket(ZMQ.SUB);
socket.connect("tcp://192.168.124.130:6666");
socket.subscribe("".getBytes());
while(true){
byte[] res =socket.recv(0);
String resStr = new String(res);
System.out.println("substring is ="+resStr);
if("END".equalsIgnoreCase(resStr)){
break;
}
}
System.out.println("===========subscriber end=============");
socket.close();
context.term();
}
}
說明：
在啓動Subscriber程序後，啓動publisher程序。重要的是這個模式下publisher的消息可以被同時多個subscriber程序接收並處理。實現廣播的方式。
