android客户端代码:
public class MainActivity extends Activity
{

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}
public void uploadFile()
{
//服务器端地址
String url = "http://192.168.0.108:8080/UploadFileServer/upload";
//手机端要上传的文件，首先要保存你手机上存在该文件
String filePath = Environment.getExternalStorageDirectory()
+ "/1/power.apk";
AsyncHttpClient httpClient = new AsyncHttpClient();

服务器端代码：
public class UploadFileServlet extends HttpServlet
{
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
// 创建文件项目工厂对象
DiskFileItemFactory factory = new DiskFileItemFactory();
// 设置文件上传路径
String upload = this.getServletContext().getRealPath("/upload/");
// 获取系统默认的临时文件保存路径，该路径为Tomcat根目录下的temp文件夹
String temp = System.getProperty("java.io.tmpdir");
// 设置缓冲区大小为 5M
factory.setSizeThreshold(1024 * 1024 * 5);
// 设置临时文件夹为temp
factory.setRepository(new File(temp));
// 用工厂实例化上传组件,ServletFileUpload 用来解析文件上传请求
ServletFileUpload servletFileUpload = new ServletFileUpload(factory);
// 解析结果放在List中
try
{
List
for (FileItem item : list)
{
String name = item.getFieldName();
InputStream is = item.getInputStream();
if (name.contains("content"))
{
System.out.println(inputStream2String(is));
} else if(name.contains("file"))
{
try
{
inputStream2File(is, upload + "\\" + item.getName());
} catch (Exception e)
{
e.printStackTrace();
}
}
}
out.write("success");
} catch (FileUploadException e)
{
e.printStackTrace();
out.write("failure");
}
out.flush();
out.close();
}
// 流转化成字符串
public static String inputStream2String(InputStream is) throws IOException
{
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int i = -1;
while ((i = is.read()) != -1)
{
baos.write(i);
}
return baos.toString();
}
// 流转化成文件
public static void inputStream2File(InputStream is, String savePath)
throws Exception
{

File file = new File(savePath);
InputStream inputSteam = is;
BufferedInputStream fis = new BufferedInputStream(inputSteam);
FileOutputStream fos = new FileOutputStream(file);
int f;

fos.close();

inputSteam.close();
}
}
ftp做，java不用写代码，让手机去写
