简单3步走。搞定！
上传文件成功后：
1 上传文件核心方法
public static String saveWebImgFile(MultipartFile imgFile){
String webFilePath = "";
if(imgFile.getSize() > 0 && isImage(imgFile.getContentType())){
FileOutputStream fos = null;
try {
byte[] b = imgFile.getBytes();
/* 构造文件路径 */
String webRoot = PathUtil.classPath();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
SimpleDateFormat sdf2 = new SimpleDateFormat("HHmmssSSS");
String datePath = sdf.format(new Date());
String datePath2 = sdf2.format(new Date());
String dirPath = webRoot + "/../../upload/img/" + datePath;
File dir = new File(dirPath);
if(!dir.exists()){
dir.mkdirs();
}
String fileName = imgFile.getOriginalFilename();
String filePath = dirPath + "/" + datePath2 + getImgSuffix(fileName);
webFilePath = "/upload/img/" + datePath + "/" + datePath2 + getImgSuffix(fileName);
File file = new File(filePath);
dir.setWritable(true);
file.setWritable(true);
fos = new FileOutputStream(file);
fos.write(b);
} catch (IOException e) {
throw new RuntimeException("文件上传失败！" ,e);
}finally{
if(fos != null){
try {
fos.close();
} catch (IOException e) {
throw new RuntimeException("文件上传->输出流关闭失败！！！！" ,e);
}
}
}
}
return webFilePath;
}
@RequestMapping(value = "/imgupload")
public String handleFormUpload(MultipartHttpServletRequest request) throws Exception{
List<MultipartFile> files = request.getFiles("file");
Map<String, String> imgs = new HashMap<String, String>();
for (int i = 0; i < files.size(); i++) {
String webpath = FileUtil.saveWebImgFile(files.get(i));
imgs.put("img"+i, webpath);
}
request.setAttribute("imgs", imgs);
return showImageList(request);
}3 页面代码
<body>
商品图片设置：
<form method="post" enctype="multipart/form-data" action="product/imgupload" name="imagefrm">
