Question

java 通过app上传图片失败

MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
// 获得图片（根据前台的name名称得到上传的文件）
MultipartFile imgFile = multipartRequest.getFile("headImg");
String path = request.getSession().getServletContext().getRealPath("/");
System.out.println("path=="+path);
String oname = imgFile.getOriginalFilename();
if (FileUtil.isImage(oname)) {
String newFilePath = "upload/user/headImg/"+ System.currentTimeMillis()+ FileUtil.getPostFix(oname);
String tempFilePath = "upload/user/headImg/temp_"+ System.currentTimeMillis() + "."+ FileUtil.getPostFix(oname);
String headImg = user.getHeadImg();
if (headImg != null) {
FileUtil.deleteFile(path + headImg);
}
try {
File tempFile = new File(path + tempFilePath);
FileUtil.writeByteToFile(tempFile, imgFile.getBytes());
ImageUtil.genarateSmallPic(tempFile.getAbsolutePath(), path
+ newFilePath, //设置图片的高宽度
CONSTANT.USER_HEADIMG,
CONSTANT.USER_HEADIMG);
user.setHeadImg(newFilePath);
if (userService.editUserByToken(user)) {
dataMap.put("status", 200);
dataMap.put("headImg", fullImagePath(request, newFilePath));
dataMap.put("status", 200);
dataMap.put("message", "修改成功");
return dataMap;
}
tempFile.delete();
} catch (IOException e) {
e.printStackTrace();
}
}
提示第一行就错误了。

你看看你这个配的是POST吗（form和RequestMapping）？我看的你错误信息是走的GET方法啊，

form 里是否有enctype="multipart/form-data"
