java socket怎么建立连接池

Answer 1

socket连接池

SocketServerPool 含有两个参数 listenPort , maxConnection 。分别表示监听端口和最大连接数。

函数setHandlers() 里面初始化了5个PoolConnectionHandler的线程，表示池中能同时最大处理5个连接。

public class SocketServerPool {

/*最大连接和监听端口*/
private int maxConnections ;
private int listenPort ;

public SocketServerPool(int listenPort , int maxConnections){
this.listenPort = listenPort ;
this.maxConnections = maxConnections ;

}
public void acceptConnections(){
try {
ServerSocket serverSocket = new ServerSocket(listenPort , 5) ;
Socket socket= null ;
while(true)
{
socket = serverSocket.accept() ;
PoolConnectionHandler.processRequest(socket) ;
}
} catch (IOException e) {
e.printStackTrace();
}

}

public void setHandlers()
{
for(int i = 0 ; i < this.maxConnections ; i++ )
{
PoolConnectionHandler poolHandler = new PoolConnectionHandler() ;
new Thread(poolHandler , "handler" + i).start() ;
}
}

public static void main(String [] args)
{
SocketServerPool pool = new SocketServerPool(8888 , 5) ;
pool.setHandlers() ;
pool.acceptConnections() ;
}

}
