shiro项目介绍
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...
功能新增
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
项目结构
java：代码
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<ObjectError> 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;
}
