文件上传到本地服务器,Java实现上传文件到本地服务器

static void main(String[] args) throws IOException {

//目标路径

String filePath = "E:"+File.separator+"test"+File.separator;

File file = new File(filePath);

//如果文件目录不存在，就执行创建

if(!file.isDirectory()){

file.mkdirs();

}

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHss");

//目标文件名称

String targetName =sdf.format(new Date()) + ".jpg";

System.out.println(targetName);

//创建目标文件

File targetFile = new File(filePath + targetName);

FileOutputStream fos = new FileOutputStream(targetFile);

//读取本地文件

File localFile = new File("E:"+File.separator+"1.jpg");

//获取本地文件输入流

InputStream stream = new FileInputStream(localFile);

//写入目标文件

byte[] buffer = new byte[1024*1024];

int byteRead = 0;

while((byteRead=stream.read(buffer))!=-1){

fos.write(buffer, 0, byteRead);

fos.flush();

}

fos.close();

stream.close();

}
