给指定ip端口发送一串字符
java 给指定ip端口发送一串字符，该怎么做啊？ java --------------------编程问答-------------------- http://blog.sina.com.cn/s/blog_5686c3640100rq3y.html --------------------编程问答-------------------- 写个socket就可以了 --------------------编程问答-------------------- 通过webservice可以实现，你写个客户端，去调用对方的webservice，把字符串传送给它就ok。 --------------------编程问答-------------------- ip ,port 用socket 不管对方是什么 --------------------编程问答-------------------- 给你贴一段实例代码吧：服务器端：
import java.io.*;
import java.net.*;
public class MyServer {
public static void main(String[] args) throws IOException{
ServerSocket server=new ServerSocket(5678);
Socket client=server.accept();
BufferedReader in=
new BufferedReader(new InputStreamReader(client.getInputStream()));
PrintWriter out=new PrintWriter(client.getOutputStream());
while(true){
String str=in.readLine();
System.out.println(str);
out.println("has receive....");
out.flush();
if(str.equals("end")) //如果发送的是end，则退出
break;
}
client.close();
}
}
客户端：
--------------------编程问答-------------------- 用socket，楼上有例子了
import java.net.*;
import java.io.*;
public class Client{
static Socket server;
public static void main(String[] args)throws Exception{
server=new Socket(InetAddress.getLocalHost(),5678);
BufferedReader in=
new BufferedReader(new InputStreamReader(server.getInputStream()));
PrintWriter out=new PrintWriter(server.getOutputStream());
BufferedReader wt=new BufferedReader(new InputStreamReader(System.in));
while(true){
String str=wt.readLine();
out.println(str);
out.flush();
if(str.equals("end")){ //如果发送的是end，则退出
break;
}
System.out.println(in.readLine());
}
server.close();
}
}
补充：Java , Web 开发
