安卓客户端利用MultipartFile上传图片，服务端（spring3）获取上传的图片
@Controller
public class FileUpoadController {
@RequestMapping(value = "/form", method = RequestMethod.POST)
public String handleFormUpload(@RequestParam("name") String name,
@RequestParam("file") MultipartFile file) {
if (!file.isEmpty()) {
byte[] bytes = file.getBytes();
// store the bytes somewhere
return "redirect:uploadSuccess";
} else {
return "redirect:uploadFailure";
}
}
}
一个完整的例子

2、上述方式不能用于接收android发来的请求
/**
* 上传图片
*
* */
@ModelAttribute()
@RequestMapping(value = "/addFile", method = RequestMethod.POST)
@ResponseBody
public String addFile(HttpServletRequest request) {
String result = "";
FileResult json = new FileResult();
json.setSuccess(false);
long userId = 0;
String name = "";
boolean isMultipart = ServletFileUpload.isMultipartContent(request);
if (isMultipart) {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
try {
List items = upload.parseRequest(request);
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
if (item.isFormField()) {
// 普通文本信息处理
String paramName = item.getFieldName();
String paramValue = item.getString();
//System.out.println(paramName + ":" + paramValue);
if (paramName.equalsIgnoreCase("userId")) {
userId = Long.valueOf(paramValue);
}
} else {
// 上传文件信息处理
name = item.getName();
result = addFile.addFile(userId, name,
item.getInputStream());
}
}
} catch (Exception e) {
json.setErrorMsg("上传图片出错" + e.getMessage());
result = JSONObject.fromObject(json).toString();
log.error("上传图片出错" + e.getMessage());
}
}
return result;
}
