今天完成了什么：

dao层

public interface UserMapper {
    List<User>selectName(String name);

    int insert(User record);

    User select(String name);
}

service

public interface UserService {
    List<User>selectName(String name);

    User login(String name,String password);

    int insert(User record);

}

serviceimpl

@Service
public class UserServiceImpl implements UserService {
    @Autowired
    UserMapper userMapper;

    @Override
    public User login(String name, String password) {

        User user = userMapper.select(name);

        if (user != null && MD5Util.MD5(password).equals(MD5Util.MD5(user.getPassword()))) {

            return user;
        }
        return null;
    }

    @Override
    public int insert(User record) {
        String password = MD5Util.MD5(record.getPassword());
        record.setPassword(password);
        return userMapper.insert(record);
    }

    @Override
    public List<User> selectName(String name) {
        return userMapper.selectName(name);
    }
}

controller未完成

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

public String selectAll(DESUtil desUtil, HttpServletResponse response, @RequestParam String name, @RequestParam String password) throws Exception {

    User user2=userService.login(name,password);

    if (!ObjectUtils.isEmpty(user2)) {

        String token=desUtil.encrypt(user2.getId()+"/"+System.currentTimeMillis());

        System.out.println("加密的token================"+token);

        String decrypt = desUtil.decrypt(token);

        System.out.println("解密后的token==============="+decrypt);

        Cookie cookie = new Cookie("token", token);

        System.out.println("cookie是这个============="+cookie);

        cookie.setMaxAge(30*60);

        response.addCookie(cookie);

        return "student";

    }

    return "exit";

}

明天计划的事：完成controller
