一、Shiro简介
核心角色
1)Subject:认证主体
代表当前系统的使用者,就是用户,在Shiro的认证中,认证主体通常就是userName和passWord,或者其他用户相关的唯一标识。
2)SecurityManager:安全管理器
Shiro架构中最核心的组件,通过它可以协调其他组件完成用户认证和授权。实际上,SecurityManager就是Shiro框架的控制器。
3)Realm:域对象
定义了访问数据的方式,用来连接不同的数据源,如:关系数据库,配置文件等等。
核心理念
Shiro自己不维护用户和权限,通过Subject用户主体和Realm域对象的注入,完成用户的认证和授权。
二、整合SpringBoot2框架
1、核心依赖
org.apache.shiro shiro-core 1.4.0 org.apache.shiro shiro-spring 1.4.0
2、Shiro核心配置
@Configuration public class ShiroConfig { /** * Session Manager:会话管理 * 即用户登录后就是一次会话,在没有退出之前,它的所有信息都在会话中; * 会话可以是普通JavaSE环境的,也可以是如Web环境的; */ @Bean("sessionManager") public SessionManager sessionManager(){ DefaultWebSessionManager sessionManager = new DefaultWebSessionManager(); //设置session过期时间 sessionManager.setGlobalSessionTimeout(60 * 60 * 1000); sessionManager.setSessionValidationSchedulerEnabled(true); // 去掉shiro登录时url里的JSESSIONID sessionManager.setSessionIdUrlRewritingEnabled(false); return sessionManager; } /** * SecurityManager:安全管理器 */ @Bean("securityManager") public SecurityManager securityManager(UserRealm userRealm, SessionManager sessionManager) { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setSessionManager(sessionManager); securityManager.setRealm(userRealm); return securityManager; } /** * ShiroFilter是整个Shiro的入口点,用于拦截需要安全控制的请求进行处理 */ @Bean("shiroFilter") public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) { ShiroFilterFactoryBean shiroFilter = new ShiroFilterFactoryBean(); shiroFilter.setSecurityManager(securityManager); shiroFilter.setLoginUrl("/userLogin"); shiroFilter.setUnauthorizedUrl("/"); MapfilterMap = new LinkedHashMap<>(); filterMap.put("/userLogin", "anon"); shiroFilter.setFilterChainDefinitionMap(filterMap); return shiroFilter; } /** * 管理Shiro中一些bean的生命周期 */ @Bean("lifecycleBeanPostProcessor") public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() { return new LifecycleBeanPostProcessor(); } /** * 扫描上下文,寻找所有的Advistor(通知器) * 将这些Advisor应用到所有符合切入点的Bean中。 */ @Bean public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() { DefaultAdvisorAutoProxyCreator proxyCreator = new DefaultAdvisorAutoProxyCreator(); proxyCreator.setProxyTargetClass(true); return proxyCreator; } /** * 匹配所有加了 Shiro 认证注解的方法 */ @Bean public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) { AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor(); advisor.setSecurityManager(securityManager); return advisor; } }
3、域对象配置
@Component public class UserRealm extends AuthorizingRealm { @Resource private SysUserMapper sysUserMapper ; @Resource private SysMenuMapper sysMenuMapper ; /** * 授权(验证权限时调用) * 获取用户权限集合 */ @Override public AuthorizationInfo doGetAuthorizationInfo (PrincipalCollection principals) { SysUserEntity user = (SysUserEntity)principals.getPrimaryPrincipal(); if(user == null) { throw new UnknownAccountException("账号不存在"); } ListpermsList; //默认用户拥有最高权限 List menuList = sysMenuMapper.selectList(); permsList = new ArrayList<>(menuList.size()); for(SysMenuEntity menu : menuList){ permsList.add(menu.getPerms()); } //用户权限列表 Set permsSet = new HashSet<>(); for(String perms : permsList){ if(StringUtils.isEmpty(perms)){ continue; } permsSet.addAll(Arrays.asList(perms.trim().split(","))); } SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(); info.setStringPermissions(permsSet); return info; } /** * 认证(登录时调用) * 验证用户登录 */ @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken authToken) throws AuthenticationException { UsernamePasswordToken token = (UsernamePasswordToken)authToken; //查询用户信息 SysUserEntity user = sysUserMapper.selectOne(token.getUsername()); //账号不存在 if(user == null) { throw new UnknownAccountException("账号或密码不正确"); } //账号锁定 if(user.getStatus() == 0){ throw new LockedAccountException("账号已被锁定,请联系管理员"); } SimpleAuthenticationInfo info = new SimpleAuthenticationInfo (user, user.getPassword(), ByteSource.Util.bytes(user.getSalt()), getName()); return info; } @Override public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) { HashedCredentialsMatcher shaCredentialsMatcher = new HashedCredentialsMatcher(); shaCredentialsMatcher.setHashAlgorithmName(ShiroUtils.hashAlgorithmName); shaCredentialsMatcher.setHashIterations(ShiroUtils.hashIterations); super.setCredentialsMatcher(shaCredentialsMatcher); } }
4、核心工具类
public class ShiroUtils { /** 加密算法 */ public final static String hashAlgorithmName = "SHA-256"; /** 循环次数 */ public final static int hashIterations = 16; public static String sha256(String password, String salt) { return new SimpleHash(hashAlgorithmName, password, salt, hashIterations).toString(); } // 获取一个测试账号 admin public static void main(String[] args) { // 3743a4c09a17e6f2829febd09ca54e627810001cf255ddcae9dabd288a949c4a System.out.println(sha256("admin","123")) ; } /** * 获取会话 */ public static Session getSession() { return SecurityUtils.getSubject().getSession(); } /** * Subject:主体,代表了当前“用户” */ public static Subject getSubject() { return SecurityUtils.getSubject(); } public static SysUserEntity getUserEntity() { return (SysUserEntity)SecurityUtils.getSubject().getPrincipal(); } public static Long getUserId() { return getUserEntity().getUserId(); } public static void setSessionAttribute(Object key, Object value) { getSession().setAttribute(key, value); } public static Object getSessionAttribute(Object key) { return getSession().getAttribute(key); } public static boolean isLogin() { return SecurityUtils.getSubject().getPrincipal() != null; } public static void logout() { SecurityUtils.getSubject().logout(); } }
5、自定义权限异常提示
@RestControllerAdvice public class ShiroException { @ExceptionHandler(AuthorizationException.class) public String authorizationException (){ return "抱歉您没有权限访问该内容!"; } @ExceptionHandler(Exception.class) public String handleException(Exception e){ return "系统异常!"; } }
三、案例演示代码
1、测试接口
@RestController public class ShiroController { private static Logger LOGGER = LoggerFactory.getLogger(ShiroController.class) ; @Resource private SysMenuMapper sysMenuMapper ; /** * 登录测试 * http://localhost:7011/userLogin?userName=admin&passWord=admin */ @RequestMapping("/userLogin") public void userLogin ( @RequestParam(value = "userName") String userName, @RequestParam(value = "passWord") String passWord){ try{ Subject subject = ShiroUtils.getSubject(); UsernamePasswordToken token = new UsernamePasswordToken(userName, passWord); subject.login(token); LOGGER.info("登录成功"); }catch (Exception e) { e.printStackTrace(); } } /** * 服务器每次重启请求该接口之前必须先请求上面登录接口 * http://localhost:7011/menu/list 获取所有菜单列表 * 权限要求:sys:user:shiro */ @RequestMapping("/menu/list") @RequiresPermissions("sys:user:shiro") public List list(){ return sysMenuMapper.selectList() ; } /** * 用户没有该权限,无法访问 * 权限要求:ccc:ddd:bbb */ @RequestMapping("/menu/list2") @RequiresPermissions("ccc:ddd:bbb") public List list2(){ return sysMenuMapper.selectList() ; } /** * 退出测试,退出后没有任何权限 */ @RequestMapping("/userLogOut") public String logout (){ ShiroUtils.logout(); return "success" ; } }
2、测试流程
1)、登录后取得权限
http://localhost:7011/userLogin?userName=admin&passWord=admin
2)、访问有权限接口
http://localhost:7011/menu/list
3)、访问无权限接口
http://localhost:7011/menu/list2
4)、退出登录
http://localhost:7011/userLogOut
