@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping(value = "/register", method = RequestMethod.POST)
    public String register(User user) {
        userService.register(user);
        return "redirect:/login";
    }

    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public String login(User user, HttpSession session) {
        User loginUser = userService.login(user);
        if (loginUser == null) {
            return "redirect:/login?error=true";
        }
        session.setAttribute("user", loginUser);
        return "redirect:/project/list";
    }

    @RequestMapping("/logout")
    public String logout(HttpSession session) {
        session.invalidate();
        return "redirect:/login";
    }

    @RequestMapping("/info")
    public String info() {
        return "user_info";
    }

    @RequestMapping(value = "/update", method = RequestMethod.POST)

    public String save(File file, MultipartFile uploadFile) throws IOException {
        String filename = uploadFile.getOriginalFilename();
        String suffix = filename.substring(filename.lastIndexOf(".") + 1);
        String newName = UUID.randomUUID().toString() + "." + suffix;
        File dest = new File("d:/upload", newName);
        uploadFile.transferTo(dest);
        file.setFileName(newName);
        file.setFileType(uploadFile.getContentType());
        file.setFileSize(uploadFile.getSize());

    }

    @RequestMapping("/download/{id}")
    public void download(@PathVariable("id") int id, HttpServletResponse response) throws IOException {

        String filePath = "d:/upload/" + file.getFileName();
        FileInputStream fis = new FileInputStream(filePath);
        response.setCharacterEncoding("utf-8");
        response.setContentType("application/octet-stream");
        response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(file.getFileName(), "utf-8"));
        IOUtils.copy(fis, response.getOutputStream());
        fis.close();
    }

    @RequestMapping("/delete/{id}")
    public String delete(@PathVariable("id") int id, @RequestParam("projectId") int projectId) {

        return "redirect:/file/list?projectId=" + projectId;
    }
}

- 日志管理：

@Controller
@RequestMapping("/log")
public class LogController {

    private LogService logService;

    @RequestMapping("/list")
    public String list(Model model) {
        List<Log> logs = logService.list();
        model.addAttribute("logs", logs);
