方法一：
controller层
@RequestMapping(value ="/addSpot",
method = RequestMethod.POST,
produces = {"application/json;charset=UTF-8"})
@ResponseBody
public ChinaMapBackResult addSpot(@RequestParam("spotName")String spotName, @RequestParam("file")MultipartFile file){
ChinaMapBackResult result;
Spot spot =new Spot();
spot.setSpot_name(spotName);
try {
AllResult allResult =spotService.saveSpot(spot,file);
result =new ChinaMapBackResult(true,allResult);
}catch (Exception e){
logger.error(e.getMessage(),e);
result =new ChinaMapBackResult(false,"服务器内部错误");
}
return result;
}
service层
public AllResult saveSpot(Spot spot, MultipartFile file)throws Exception{
try{
Spot spot1 =spotDao.getSpotByName(spot.getSpot_name(),spot.getSpot_area_id());
if(spot1 ==null){
if(file !=null){
// 生成图片存储的名称，UUID 避免相同图片名冲突
String originalFileName = file.getOriginalFilename();// 原始文件名
String suffix = originalFileName.substring(originalFileName.lastIndexOf("."));// 图片后缀
String fileName = UUID.randomUUID().toString() + suffix;
String filePath = Constants.IMG_PATH_SPOT + fileName;
String sqlPath ="uploadimg/spotImg/"+fileName;
File saveFile =new File(filePath);
try {
// 将上传的文件保存到服务器文件系统
file.transferTo(saveFile);
// 记录服务器文件系统图片名称
spot.setSpot_img(sqlPath);
}catch (IOException e) {
e.printStackTrace();
}
}
String spotName = spot.getSpot_name();
spotDao.addSpot(spotName,spotImg);
return new AllResult(StateEnum.ADD_SUCCESS);
}
return new AllResult(StateEnum.FAILURE);
}catch (Exception e) {
logger.error(e.getMessage(),e);
throw e;
}
}
方法二：
@Controller
public class uploadImage {
@RequestMapping(value ="upload", method = RequestMethod.POST, produces = {"application/json;charset=UTF-8"})
@ResponseBody
public String uploadImage(HttpServletRequest request， @RequestParam("description") String description, @RequestParam("file")MultipartFile file) {
try {
System.out.println(description);
if (!file.isEmpty()) {
// 上传文件路径
String path = request.getServletContext().getRealPath("/imagesTest/");
// 上传文件
String filename = file.getOriginalFilename();
File filepath =new File(path, filename);
if (!filepath.getParentFile().exists()) {
filepath.getParentFile().mkdirs();
}
// 将上传的文件保存在一个目标文件中
file.transferTo(new File(path + File.separator + filename));
return "success";
}else {
return "error";
}
}catch (Exception e) {
