javasocket服務(wù)端技巧
Java的主要工作是通過編程語言來制作互聯(lián)網(wǎng)頁面、制作動態(tài)效果以及網(wǎng)站等技術(shù)，以下是小編為大家搜索整理的javasocket服務(wù)端技巧，歡迎閱讀!更多精彩內(nèi)容請及時關(guān)注我們應(yīng)屆畢業(yè)生考試網(wǎng)!
如下的GreetingServer 程序是一個服務(wù)器端應(yīng)用程序，使用Socket來監(jiān)聽一個指定的端口。
// 文件名 GreetingServer.java
import java.net.*;
import java.io.*;
public class GreetingServer extends Thread
{
private ServerSocket serverSocket;
public GreetingServer(int port) throws IOException
{
serverSocket = new ServerSocket(port);
serverSocket.setSoTimeout(10000);
}
public void run()
{
while(true)
{
try
{
System.out.println("Waiting for client on port " +
serverSocket.getLocalPort() + "...");
Socket server = serverSocket.accept();
System.out.println("Just connected to "
+ server.getRemoteSocketAddress());
DataInputStream in =
new DataInputStream(server.getInputStream());
System.out.println(in.readUTF());
DataOutputStream out =
new DataOutputStream(server.getOutputStream());
out.writeUTF("Thank you for connecting to "
+ server.getLocalSocketAddress() + "\nGoodbye!");
server.close();
}catch(SocketTimeoutException s)
{
System.out.println("Socket timed out!");
break;
}catch(IOException e)
{
e.printStackTrace();
break;
}
}
}
public static void main(String [] args)
{
int port = Integer.parseInt(args[0]);
try
{
Thread t = new GreetingServer(port);
t.start();
}catch(IOException e)
{
e.printStackTrace();
}
}
}
編譯以上 java 代碼，并執(zhí)行以下命令來啟動服務(wù)，使用端口號為 6066：
$ java GreetingServer 6066
Waiting for client on port 6066...
像下面一樣開啟客戶端：
$ java GreetingClient localhost 6066
Connecting to localhost on port 6066
Just connected to localhost/127.0.0.1:6066
Server says Thank you for connecting to /127.0.0.1:6066
Goodbye!
