SpringBoot整合Shiro框架,实现用户权限管理
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<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.4.0</version></dependency><dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.4.0</version></dependency>2、Shiro核心配置
@Configurationpublic 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JSESSIONIDsessionManager.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('/');Map<String, String> filterMap = 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
@Componentpublic 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');}List<String> permsList;//默认用户拥有最高权限List<SysMenuEntity> menuList = sysMenuMapper.selectList();permsList = new ArrayList<>(menuList.size());for(SysMenuEntity menu : menuList){ permsList.add(menu.getPerms());}//用户权限列表Set<String> 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) {// 3743a4c09a17e6f2829febd09ca54e627810001cf255ddcae9dabd288a949c4aSystem.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
@RestControllerAdvicepublic 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
@RestControllerpublic 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=admin2)、访问有权限接口http://localhost:7011/menu/list3)、访问无权限接口http://localhost:7011/menu/list24)、退出登录http://localhost:7011/userLogOut
