利用线程和管道的方式从客户端向服务的进行传送照片

客户端：

import java.io.*;
//客户端
public class PictureClient extends Thread{
PipedOutputStream pos;
public PictureClient() {
// TODO Auto-generated constructor stub
}
public PictureClient(PipedOutputStream pos,String name) {
this.pos = pos;
setName(name);
}
private void WritePicture() {//添加读取该图片的方法
//读取源文件
String path = "src\作业2\WeChat.jpeg";
try {
FileInputStream fs = new FileInputStream(path);
byte[] b = new byte[1024];
int count = 0;
while ((count = fs.read(b))!=-1) {//从is中读取b大小的内容存放到b中去。
pos.write(b);
pos.flush();
}
pos.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void run() {
//发送字符串，选择Data流
WritePicture();
}
}

服务器端：

import java.io.*;

public class PictureServer extends Thread {
PipedInputStream pis;
public PictureServer() {
// TODO Auto-generated constructor stub
}
public PictureServer(PipedInputStream pis,String name) {
super();
this.pis = pis;
setName(name);
}
private void ReaderPicture() {//添加写入到服务器端的方法
String path2 = "src\作业2\We.jpeg";
try {
OutputStream os = new FileOutputStream(path2);
byte[] b = new byte[1024];
int count = 0;
while ((count = pis.read(b))!=-1) {//从is中读取b大小的内容存放到b中去。
os.write(b);
os.flush();
}
os.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void run() {
ReaderPicture();
}
}

测试：

import java.io.*;

public class PictureThread {
public static void main(String[] args) {
PipedInputStream pis = new PipedInputStream();

try {
PipedOutputStream pos = new PipedOutputStream(pis);
PictureClient pc = new PictureClient(pos,"发送方：");
PictureServer ps = new PictureServer(pis,"接收方：");
pc.start();
ps.start();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
