SpringMVC上传文件路径问题

控制器代码如下：

发现上传的图片总是上传至项目的target目录中去，并且在jsp页面无法访问图片资源

@Controller
public class FileUploadController {
    @Autowired
    ServletContext context;

    @RequestMapping(value="/fileUploadPage",method=RequestMethod.GET)
    public ModelAndView fileUploadPage(){
        FileModel file=new FileModel();
        ModelAndView modelAndView=new ModelAndView("fileUpload","command",file);
        return modelAndView;
    }

    @RequestMapping(value="/fileUploadPage",method=RequestMethod.POST)
    public String fileUpload(@Validated FileModel file, BindingResult result,ModelMap model,HttpServletRequest request) throws Exception{
        if (result.hasErrors()){
            System.out.println("validation errors");
            return "fileUploadPage";
        }else {
            System.out.println("Fetching file");
            MultipartFile multipartFile=file.getFile();
            String uploadPath=request.getSession().getServletContext().getRealPath("")+File.separator+"tmp"+File.separator;
            System.out.println("FileUploadController::Picpath：："+uploadPath);
            FileCopyUtils.copy(file.getFile().getBytes(), new File(uploadPath+file.getFile().getOriginalFilename()));
            String fileName = multipartFile.getOriginalFilename();
            model.addAttribute("filepath", "/pic/"+fileName);
            return "success";
        }
    }

success.jsp
