我的外网IP 192.168.1.15
启动tomcat
服务器端：
另起一个eclipse，换工作空间，新建一个java项目。
在包com.li.util里新建UploadFile.java：
package com.li.util;
import java.io.Serializable;
@SuppressWarnings("serial")
public class UploadFile implements Serializable {
private String title ;
private byte [] contentData ;
private String mimeType ;
private long contentLength ;
private String ext ;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public byte[] getContentData() {
return contentData;
}
public void setContentData(byte[] contentData) {
this.contentData = contentData;
}
public String getMimeType() {
return mimeType;
}
public void setMimeType(String mimeType) {
this.mimeType = mimeType;
}
public long getContentLength() {
return contentLength;
}
public void setContentLength(long contentLength) {
this.contentLength = contentLength;
}
public String getExt() {
return ext;
}
public void setExt(String ext) {
this.ext = ext;
}
}
在包com.li.server里新建ServerThreadUtil.java：
package com.li.server;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.OutputStream;
import java.io.PrintStream;
import java.net.Socket;
import java.util.UUID;
import com.li.util.UploadFile;
public class ServerThreadUtil implements Runnable {
private static final String DIRPATH = "D:" + File.separator + "liyewenfile"
+ File.separator; // 目录路径
private Socket client = null;
private UploadFile upload = null;
public ServerThreadUtil(Socket client) {
this.client = client;
System.out.println("新的客户端连接...");
}
@Override
public void run() {
try {
PrintStream out = new PrintStream(this.client.getOutputStream());
ObjectInputStream ois = new ObjectInputStream(
client.getInputStream()); // 反序列化
this.upload = (UploadFile) ois.readObject(); // 读取对象
System.out.println("文件标题：" + this.upload.getTitle());
System.out.println("文件类型：" + this.upload.getMimeType());
System.out.println("文件大小：" + this.upload.getContentLength());
out.print(this.saveFile()) ;
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
this.client.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
private boolean saveFile() throws Exception { // 负责文件内容的保存
File file = new File(DIRPATH + UUID.randomUUID() + "."
+ this.upload.getExt());
if (!file.getParentFile().exists()) {
file.getParentFile().mkdir();
}
OutputStream output = null;
try {
output = new FileOutputStream(file) ;
output.write(this.upload.getContentData()) ;
return true ;
} catch (Exception e) {
throw e;
} finally {
output.close();
}
}
}
在包com.li.server里新建MyServer.java：
package com.li.server;
import java.net.ServerSocket;
public class MyServer {
public static void main(String[] args) throws Exception {
ServerSocket server = new ServerSocket(8888); // 服务器端端口
boolean flag = true; // 定义标记，可以一直死循环
while (flag) { // 通过标记判断循环
new Thread(new ServerThreadUtil(server.accept())).start(); // 启动线程
}
server.close(); // 关闭服务器
}
}
客户端：
在sdcard里面存放一张名为disney的图片。
在main.xml中：

在com.li. util包UploadFile.java中：
