在之前的shiro整合项目之后，更加完善shiro功能，之前的代码不予展示与介绍，想了解的请参考shiro整合项目
项目代码获取：https://github.com/pysasuke/s...

用户注册

登录错误次数限制(使用redis作缓存)

shiro注解配置

DTO引入

数据校验(使用hibernate validation)

SpringMVC统一异常处理配置

controller:控制层，以下展示注册和登录功能

    @RequestMapping("/login")
    public String login(ShiroUser shiroUser, HttpServletRequest request) {
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(shiroUser.getUsername(), shiroUser.getPassword());
        try {
            subject.login(token);//会跳到我们自定义的realm中
            request.getSession().setAttribute("user", shiroUser);
            log.info(shiroUser.getUsername() + "登录");
            return "user/success";
        } catch (UnknownAccountException e) {
            return "user/login";
        } catch (IncorrectCredentialsException e) {
            request.setAttribute("error", "用户名或密码错误");
            return "user/login";
        } catch (ExcessiveAttemptsException e) {
            request.setAttribute("error", "输入密码错误太多次,请稍后再试！");
            return "user/login";
        } catch (Exception e) {
            request.setAttribute("error", "未知错误");
            return "user/login";
        }
    }
    
    @RequestMapping(value = "/register", method = RequestMethod.POST)
    public String register(Model model,
                           @Valid @ModelAttribute ShiroUserDTO shiroUserDTO, BindingResult bindingResult) {
        //数据校验
        if (bindingResult.hasErrors()) {
            List allErrors = bindingResult.getAllErrors();
            for (ObjectError objectError : allErrors) {
                //输出错误信息
                System.out.println(objectError.getDefaultMessage());
            }
            model.addAttribute("error", "填入信息有误");
            model.addAttribute("user", shiroUserDTO);
            return "/user/register";
        }
        if (shiroUserService.getByUsername(shiroUserDTO.getUsername()) == null) {
            shiroUserService.insertUser(shiroUserDTO);
            return "redirect:/";
        } else {
            model.addAttribute("user", shiroUserDTO);
            model.addAttribute("error", "userName has been registered!");
            return "/user/register";
        }
    }

service:业务处理层，以下展示新增用户功能，包含数据转换(DTO到Entity)和密码加密(shiro加密策略)

 public void insertUser(ShiroUserDTO shiroUserDTO) {
        ShiroUser shiroUser = converToAddress(shiroUserDTO);
        shiroUserMapper.insert(shiroUser);
    }
  
 private ShiroUser converToAddress(ShiroUserDTO shiroUserDTO) {
        ShiroUser shiroUser = new ShiroUser();
        BeanUtils.copyProperties(shiroUserDTO, shiroUser);
        passwordEncrypt(shiroUser);
        shiroUser.setCreatetime(new Date());
        shiroUser.setRoleId(1);
        return shiroUser;
    }

  private void passwordEncrypt(ShiroUser shiroUser) {
        String username = shiroUser.getUsername();
        String password = shiroUser.getPassword();
        String salt2 = new SecureRandomNumberGenerator().nextBytes().toHex();
        int hashIterations = 3;
        String algorithmName = "md5";
        SimpleHash hash = new SimpleHash(algorithmName, password,
                username + salt2, hashIterations);
        String encodedPassword = hash.toHex();
        shiroUser.setSalt(salt2);
        shiroUser.setPassword(encodedPassword);
    }

dao:数据库交互层

entity:实体对象层,以下展示数据校验

@Data
public class ShiroUser {
    private Integer id;
    
    @NotNull(message = "用户名不能为空")
    @Size(min = 3, max = 16, message = "用户名长度必须介于3-16个字符之间")
    
    private String username;
    
    @NotNull(message = "密码不能为空")
    @Size(min = 3, max = 16, message = "{密码长度必须介于3-16个字符之间")
    private String password;
    
    private Date createtime;
    
    private Date lasttime;
    
    @Email(message = "请输入正确的邮箱")
    private String email;
    
    private String sex;
    
    private String salt;
    
    private Integer roleId;
}

realm:自定义Realm(shiro相关)，以下加入了加密相关代码

public class MyRealm extends AuthorizingRealm {

    @Resource
    private ShiroUserService shiroUserService;

    // 为当前登陆成功的用户授予权限和角色，已经登陆成功了
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(
            PrincipalCollection principals) {
        String username = (String) principals.getPrimaryPrincipal(); //获取用户名
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        authorizationInfo.setRoles(shiroUserService.getRoles(username));
        authorizationInfo.setStringPermissions(shiroUserService.getPermissions(username));
        return authorizationInfo;
    }

    // 验证当前登录的用户，获取认证信息
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(
            AuthenticationToken token) throws AuthenticationException {
        String username = (String) token.getPrincipal(); // 获取用户名
        ShiroUser shiroUser = shiroUserService.getByUsername(username);
        if (shiroUser != null) {
            SimpleAuthenticationInfo authcInfo = new SimpleAuthenticationInfo(shiroUser.getUsername(), shiroUser.getPassword(), "myRealm");
            //通过SimpleAuthenticationInfo的credentialsSalt设置盐，HashedCredentialsMatcher会自动识别这个盐。
            authcInfo.setCredentialsSalt(ByteSource.Util.bytes(shiroUser.getUsername() + shiroUser.getSalt()));
            return authcInfo;
        } else {
            return null;
        }
    }
}

constants:常量类包

dto:DTO对象包,以下展示ShiroUserDTO(只包含交互相关的字段)

@Data
public class ShiroUserDTO {

    @NotNull(message = "用户名不能为空")
    @Size(min = 3, max = 16, message = "用户名长度必须介于3-16个字符之间")
    private String username;

    @NotNull(message = "密码不能为空")
    @Size(min = 3, max = 16, message = "{密码长度必须介于3-16个字符之间")
    private String password;

    @Email(message = "请输入正确的邮箱")
    private String email;

    @NotNull(message = "请选择性别")
    private String sex;
}

credentials:处理重试次数类包

public class RetryLimitHashedCredentialsMatcher extends HashedCredentialsMatcher {

    @Autowired
    private RedisCache redisCache;


    //匹配用户输入的token的凭证（未加密）与系统提供的凭证（已加密）
    @Override
    public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
        String username = (String) token.getPrincipal();
        //retry count + 1
        //AtomicInteger是一个提供原子操作的Integer类，通过线程安全的方式操作加减。
        AtomicInteger retryCount = redisCache.getCache(Constants.USER + username, AtomicInteger.class);
        if (retryCount == null) {
            retryCount = new AtomicInteger(0);
        }
        //增长
        if (retryCount.incrementAndGet() > 5) {
            //if retry count > 5 throw
            throw new ExcessiveAttemptsException();
        }
        redisCache.putCacheWithExpireTime(Constants.USER + username, retryCount, 600);
        boolean matches = super.doCredentialsMatch(token, info);
        if (matches) {
            //clear retry count
            redisCache.deleteCache(Constants.USER + username);
        }
        return matches;
    }
}
