本文为大家分享了Java socket字节流传输示例，供大家参考，具体内容如下

服务端server端：

package com.yuan.socket;
import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;
/**
* Created by YUAN on 2016-09-17.
*/
public class TalkServer4Byte {
private ServerSocket server;
private int port = 5020;
public TalkServer4Byte() {
try {
server = new ServerSocket(port);
} catch (IOException e) {
}
}
public void talk() {
System.out.println("监控端口：" + port);
Socket socket = null;
while (true) {
try {
// 阻塞等待，每接收到一个请求就创建一个新的连接实例
socket = server.accept();
System.out.println("连接客户端地址：" + socket.getRemoteSocketAddress());
// 装饰流BufferedReader封装输入流（接收客户端的流）
BufferedInputStream bis = new BufferedInputStream(
socket.getInputStream());
DataInputStream dis = new DataInputStream(bis);
byte[] bytes = new byte[1]; // 一次读取一个byte
String ret = "";
while (dis.read(bytes) != -1) {
ret += bytesToHexString(bytes) + " ";
if (dis.available() == 0) { //一个请求
doSomething(ret);
}
}
} catch (IOException e) {
System.out.println(e.getMessage());
} finally {
try {
socket.close();
} catch (IOException e) {
System.out.println(e.getMessage());
}
}
}
}
public static void doSomething(String ret) {
System.out.println(ret);
}
public static String bytesToHexString(byte[] src) {
StringBuilder stringBuilder = new StringBuilder("");
if (src == null || src.length <= 0) {
return null;
}
for (int i = 0; i < src.length; i++) {
int v = src[i] & 0xFF;
String hv = Integer.toHexString(v);
if (hv.length() < 2) {
stringBuilder.append(0);
}
stringBuilder.append(hv);
}
return stringBuilder.toString();
}
public static String BytesHexString(byte[] b) {
String ret = "";
for (int i = 0; i < b.length; i++) {
String hex = Integer.toHexString(b[i] & 0xFF);
if (hex.length() == 1) {
hex = '0' + hex;
}
ret += hex.toUpperCase();
}
return ret;
}
public static void main(String[] args) {
TalkServer4Byte server = new TalkServer4Byte();
server.talk();
}
}

客户端client代码：

package com.yuan.socket;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
/**
* Created by YUAN on 2016-09-17.
*/
public class TalkClient4Byte {
private Socket socket;
private SocketAddress address;
public TalkClient4Byte() {
try {
socket = new Socket();
address = new InetSocketAddress("127.0.0.1", 5020);
socket.connect(address, 1000);
} catch (IOException e) {
e.printStackTrace();
}
}
public void talk() {
try {
//使用DataInputStream封装输入流
InputStream os = new DataInputStream(System.in);
byte [] b = new byte[1];
DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
while (-1 != os.read(b)) {
dos.write(b); // 发送给客户端
}
dos.flush();
dos.close();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
socket.close();
} catch (IOException e) {
}
}
}
public static void main(String[] args) {
TalkClient4Byte client = new TalkClient4Byte();
client.talk();
}
}
