			File outFile= new File("/home");
			if (!outFile.exists()) {
				outFile.mkdirs();
			}
			String outName ="/home/"   + file1FileName;
			File destFile = new File(outName);

			/*方式三：
			FileChannel inputChannel =new FileInputStream(file1).getChannel();
			FileChannel outputChannel = new FileOutputStream(destFile).getChannel();
			outputChannel.transferFrom(inputChannel, 0, inputChannel.size());*/
			//方式二：使用FileUtils工具类
			FileUtils.copyFile(file1, destFile);
