MultipartFile

1，MultipartFile是java中的抽象类

MultipartFile类型的插件继承了java中的MultipartFile

2，使用form提交，enctype=\"multipart/form-data\"必须有

3，如果form中不使用enctype=\"multipart/form-data\"，使用ajax提交

必须要加上“processData: false,contentType: false,”设置ajax

@RequestMapping(value=\"upload/upload.service\")

@ResponseBody

public Object upload(HttpServletRequest request){

MultipartHttpServletRequest file = (MultipartHttpServletRequest) request;

Iterator str=file.getFileNames();

DataResult re=new DataResult();

try {

if(str.hasNext()){

String na=str.next();

List files=file.getFiles(na);

for(int i=0;iString base=Base.encodeBaseString(files.get(i).getBytes());

String fileName=files.get(i).getOriginalFilename();

String location=\"D:/fan/\"+fileName;

File upFile=new File(location);

files.get(i).transferTo(upFile);

}

}

} catch (Exception e) {

re.setMsg(\"失败\");

e.printStackTrace();

}

return re;

}

(list.get(i).getBytes())直接使用base转换，说明MultipartFile代表一张图片的based4数据（类似）

Base.encodeBaseString(bximg(new Base().decode(imgs[i])))

List list = multipartRequest.getFiles(fileKey);

String base = \"\";

if (list!=null&&list.size()>0) {

try {

for (int i = 0; i < list.size(); i++) {

base+=\(list.get(i).getBytes()));

}
