要求上传图片到服务器目录文件夹下，以用户名+用户Id.img修改图片名称，并且将路径保存到数据库中，如果没有图片则存默认图片路径、photo/0.jgp，这个应该怎么做啊，有没有谁有这方面的源码，麻烦贴出来借鉴一下，感激不尽啊

public String upload(String dir, FormFile formFile) throws Exception {
Date date = new Date();
// 取欲上传的文件的名字和长度
String fname = formFile.getFileName();
// 将上传时间加入文件名
int i = fname.indexOf(".");
String name = String.valueOf(date.getTime());
String type = fname.substring(i + 1);
fname = name + "." + type;
InputStream streamIn = formFile.getInputStream(); // 创建读取用户上传文件的对象
File uploadFile = new File(dir); // 创建把上传数据写到目标文件的对象
if (!uploadFile.exists() || uploadFile == null) { // 判断指定路径是否存在，不存在则创建路径
uploadFile.mkdirs();
}
String path = uploadFile.getPath() + "/" + fname;
OutputStream streamOut = new FileOutputStream(path);
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = streamIn.read(buffer, 0, 8192)) != -1) {
streamOut.write(buffer, 0, bytesRead);
}
streamOut.close();
streamIn.close();
formFile.destroy();
return fname;
}
直接调用这个上传的方法就行了。
