用户信息控制层：

/*** 用户信息控制层*/@Controllerpublic class UserInfoController {     @Resource    private UserInfoService userInfoService;    @Resource    private PrivilegeService privilegeService;     @RequestMapping(value = {"/", "login.html"})    public String toLogin(HttpServletRequest request, HttpServletResponse response){        HttpSession session = request.getSession();

用户信息mapper类：

@Repositorypublic interface UserInfoMapper {     /**     * 获取单个用户信息，可用于：     * 1.登录     * 2.通过用户某一部分信息获取用户完整信息     * @param userInfo     * @return     */    UserInfo getUserInfo(UserInfo userInfo);     /**     * 注册     * @param userInfo     * @return     */    int addUser(UserInfo userInfo);     /**     * 通过username判断该用户是否存在     * @param userInfo     * @return     */    int userIsExisted(UserInfo userInfo);     /**     * 通过条件获取符合条件的优化信息 -- 分页     * @param model     * @return     */    List getUsersByWhere(PageModel model);     int getToatlByWhere(PageModel model);     int add(UserInfo userInfo);     int update(UserInfo userInfo);     int delete(String id);     List getAllRoles();     int addRole(Role role);     int updateRole(Role role);     int deleteRole(String id);     Role getRoleById(String id);     int addHouseId(House house);}
