温馨小提示：案例demo源码附文章末尾，有需要的小伙伴们可参考哦 ~
二、SpringBoot集成Shiro
1、引入相关maven依赖
<properties>
<shiro-spring.version>1.4.0</shiro-spring.version>
<shiro-redis.version>3.1.0</shiro-redis.version>
</properties>
<dependencies>
<!-- AOP依赖,一定要加,否则权限拦截验证不生效 【注：系统日记也需要此依赖】 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
<!-- Redis -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis-reactive</artifactId>
</dependency>
<!-- Shiro 核心依赖 -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>${shiro-spring.version}</version>
</dependency>
<!-- Shiro-redis插件 -->
<dependency>
<groupId>org.crazycake</groupId>
<artifactId>shiro-redis</artifactId>
<version>${shiro-redis.version}</version>
</dependency>
</dependencies>
2、自定义Realm
doGetAuthenticationInfo：身份认证 （主要是在登录时的逻辑处理）doGetAuthorizationInfo：登陆认证成功后的处理 ex: 赋予角色和权限
【 注：用户进行权限验证时 Shiro会去缓存中找,如果查不到数据,会执行doGetAuthorizationInfo这个方法去查权限,并放入缓存中 】 -> 因此我们在前端页面分配用户权限时 执行清除shiro缓存的方法即可实现动态分配用户权限
@Slf4j
public class ShiroRealm extends AuthorizingRealm {
@Autowired
private UserMapper userMapper;
@Autowired
private MenuMapper menuMapper;
@Autowired
private RoleMapper roleMapper;
@Override
public String getName() {
return "shiroRealm";
}
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
// 获取用户
User user = (User) principalCollection.getPrimaryPrincipal();
Integer userId =user.getId();
// 这里可以进行授权和处理
Set<String> rolesSet = new HashSet<>();
Set<String> permsSet = new HashSet<>();
// 获取当前用户对应的权限(这里根据业务自行查询)
List<Role> roleList = roleMapper.selectRoleByUserId( userId );
for (Role role:roleList) {
rolesSet.add( role.getCode() );
List<Menu> menuList = menuMapper.selectMenuByRoleId( role.getId() );
for (Menu menu :menuList) {
permsSet.add( menu.getResources() );
}
}
//将查到的权限和角色分别传入authorizationInfo中
authorizationInfo.setStringPermissions(permsSet);
authorizationInfo.setRoles(rolesSet);
log.info("--------------- 赋予角色和权限成功！ ---------------");
return authorizationInfo;
}
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
UsernamePasswordToken tokenInfo = (UsernamePasswordToken)authenticationToken;
// 获取用户输入的账号
String username = tokenInfo.getUsername();
// 获取用户输入的密码
String password = String.valueOf( tokenInfo.getPassword() );
// 通过username从数据库中查找 User对象，如果找到进行验证
// 实际项目中,这里可以根据实际情况做缓存,如果不做,Shiro自己也是有时间间隔机制,2分钟内不会重复执行该方法
User user = userMapper.selectUserByUsername(username);
// 判断账号是否存在
if (user == null) {
//返回null -> shiro就会知道这是用户不存在的异常
return null;
}
// 验证密码 【注：这里不采用shiro自身密码验证 ， 采用的话会导致用户登录密码错误时，已登录的账号也会自动下线！ 如果采用，移除下面的清除缓存到登录处 处理】
if ( !password.equals( user.getPwd() ) ){
throw new IncorrectCredentialsException("用户名或者密码错误");
}
// 判断账号是否被冻结
if (user.getFlag()==null|| "0".equals(user.getFlag())){
throw new LockedAccountException();
}
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user, user.getPassword(), ByteSource.Util.bytes(user.getSalt()), getName());
// 验证成功开始踢人(清除缓存和Session)
ShiroUtils.deleteCache(username,true);
// 认证成功后更新token
String token = ShiroUtils.getSession().getId().toString();
user.setToken( token );
userMapper.updateById(user);
return authenticationInfo;
}
}3、Shiro配置类
@Configuration
public class ShiroConfig {
private final String CACHE_KEY = "shiro:cache:";
private final String SESSION_KEY = "shiro:session:";
private final int EXPIRE = 1800;
@Value("${spring.redis.host}")
private String host;
@Value("${spring.redis.port}")
private int port;
@Value("${spring.redis.timeout}")
private int timeout;
// @Value("${spring.redis.password}")
// private String password;
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
return authorizationAttributeSourceAdvisor;
}
@Bean
public ShiroFilterFactoryBean shiroFilterFactory(SecurityManager securityManager, ShiroServiceImpl shiroConfig){
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.setSecurityManager(securityManager);
// 自定义过滤器
Map<String, Filter> filtersMap = new LinkedHashMap<>();
// 定义过滤器名称 【注：map里面key值对于的value要为authc才能使用自定义的过滤器】
filtersMap.put( "zqPerms", new MyPermissionsAuthorizationFilter() );
filtersMap.put( "zqRoles", new MyRolesAuthorizationFilter() );
filtersMap.put( "token", new TokenCheckFilter() );
shiroFilterFactoryBean.setFilters(filtersMap);
// 登录的路径: 如果你没有登录则会跳到这个页面中 - 如果没有设置值则会默认跳转到工程根目录下的"/login.jsp"页面 或 "/login" 映射
shiroFilterFactoryBean.setLoginUrl("/api/auth/unLogin");
// 登录成功后跳转的主页面 （这里没用，前端vue控制了跳转）
// shiroFilterFactoryBean.setSuccessUrl("/index");
// 设置没有权限时跳转的url
shiroFilterFactoryBean.setUnauthorizedUrl("/api/auth/unauth");
shiroFilterFactoryBean.setFilterChainDefinitionMap( shiroConfig.loadFilterChainDefinitionMap() );
return shiroFilterFactoryBean;
}
@Bean
public SecurityManager securityManager() {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 自定义session管理
securityManager.setSessionManager(sessionManager());
// 自定义Cache实现缓存管理
securityManager.setCacheManager(cacheManager());
// 自定义Realm验证
securityManager.setRealm(shiroRealm());
return securityManager;
}
@Bean
public ShiroRealm shiroRealm() {
ShiroRealm shiroRealm = new ShiroRealm();
shiroRealm.setCredentialsMatcher(hashedCredentialsMatcher());
return shiroRealm;
}
@Bean
public HashedCredentialsMatcher hashedCredentialsMatcher() {
HashedCredentialsMatcher shaCredentialsMatcher = new HashedCredentialsMatcher();
// 散列算法:这里使用SHA256算法;
shaCredentialsMatcher.setHashAlgorithmName(SHA256Util.HASH_ALGORITHM_NAME);
// 散列的次数，比如散列两次，相当于 md5(md5(""));
shaCredentialsMatcher.setHashIterations(SHA256Util.HASH_ITERATIONS);
return shaCredentialsMatcher;
}
@Bean
public RedisManager redisManager() {
RedisManager redisManager = new RedisManager();
redisManager.setHost(host);
redisManager.setPort(port);
redisManager.setTimeout(timeout);
// redisManager.setPassword(password);
return redisManager;
}
@Bean
public RedisCacheManager cacheManager() {
RedisCacheManager redisCacheManager = new RedisCacheManager();
redisCacheManager.setRedisManager(redisManager());
redisCacheManager.setKeyPrefix(CACHE_KEY);
// 配置缓存的话要求放在session里面的实体类必须有个id标识 注：这里id为用户表中的主键，否-> 报：User must has getter for field: xx
redisCacheManager.setPrincipalIdFieldName("id");
return redisCacheManager;
}
@Bean
public ShiroSessionIdGenerator sessionIdGenerator(){
return new ShiroSessionIdGenerator();
}
@Bean
public RedisSessionDAO redisSessionDAO() {
RedisSessionDAO redisSessionDAO = new RedisSessionDAO();
redisSessionDAO.setRedisManager(redisManager());
redisSessionDAO.setSessionIdGenerator(sessionIdGenerator());
redisSessionDAO.setKeyPrefix(SESSION_KEY);
redisSessionDAO.setExpire(EXPIRE);
return redisSessionDAO;
}
@Bean
public SessionManager sessionManager() {
ShiroSessionManager shiroSessionManager = new ShiroSessionManager();
shiroSessionManager.setSessionDAO(redisSessionDAO());
return shiroSessionManager;
}
}三、shiro动态加载权限处理方法
loadFilterChainDefinitionMap：初始化权限
ex: 在上面Shiro配置类ShiroConfig中的Shiro基础配置shiroFilterFactory方法中我们就需要调用此方法将数据库中配置的所有uri权限全部加载进去，以及放行接口和配置权限过滤器等
【注：过滤器配置顺序不能颠倒，多个过滤器用,分割】
ex: filterChainDefinitionMap.put("/api/system/user/list", "authc,token,zqPerms[user1]")
updatePermission：动态刷新加载数据库中的uri权限 -> 页面在新增uri路径到数据库中，也就是配置新的权限时就可以调用此方法实现动态加载uri权限
updatePermissionByRoleId：shiro动态权限加载 -> 即分配指定用户权限时可调用此方法删除shiro缓存，重新执行doGetAuthorizationInfo方法授权角色和权限
public interface ShiroService {
Map<String, String> loadFilterChainDefinitionMap();
void updatePermission(ShiroFilterFactoryBean shiroFilterFactoryBean, Integer roleId, Boolean isRemoveSession);
void updatePermissionByRoleId(Integer roleId, Boolean isRemoveSession);
}
@Slf4j
@Service
public class ShiroServiceImpl implements ShiroService {
@Autowired
private MenuMapper menuMapper;
@Autowired
private UserMapper userMapper;
@Autowired
private RoleMapper roleMapper;
@Override
public Map<String, String> loadFilterChainDefinitionMap() {
// 权限控制map
Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
// 配置过滤:不会被拦截的链接 -> 放行 start ----------------------------------------------------------
// 放行Swagger2页面，需要放行这些
filterChainDefinitionMap.put("/swagger-ui.html","anon");
filterChainDefinitionMap.put("/swagger
private static final String TOKEN_EXPIRED_URL = "/api/auth/tokenExpired";
@Override
public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) {
HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletResponse httpResponse = (HttpServletResponse) response;
// 根据请求头拿到token
String token = WebUtils.toHttp(request).getHeader(Constants.REQUEST_HEADER);
log.info("浏览器token：" + token );
User userInfo = ShiroUtils.getUserInfo();
String userToken = userInfo.getToken();
// 检查token是否过期
if ( !token.equals(userToken) ){
return false;
}
return true;
}
@Override
protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws IOException {
User userInfo = ShiroUtils.getUserInfo();
// 重定向错误提示处理 - 前后端分离情况下
WebUtils.issueRedirect(request, response, TOKEN_EXPIRED_URL);
return false;
}
}五、项目中会用到的一些工具类常量等
温馨小提示：这里只是部分，详情可参考文章末尾给出的案例demo源码
1、Shiro工具类
public class ShiroUtils {
private ShiroUtils(){ }
private static RedisSessionDAO redisSessionDAO = SpringUtil.getBean(RedisSessionDAO.class);
public static Session getSession() {
return SecurityUtils.getSubject().getSession();
}
public static void logout() {
SecurityUtils.getSubject().logout();
}
public static User getUserInfo() {
return (User) SecurityUtils.getSubject().getPrincipal();
}
public static void deleteCache(String username, boolean isRemoveSession){
//从缓存中获取Session
Session session = null;
// 获取当前已登录的用户session列表
Collection<Session> sessions = redisSessionDAO.getActiveSessions();
User sysUserEntity;
Object attribute = null;
// 遍历Session,找到该用户名称对应的Session
for(Session sessionInfo : sessions){
attribute = sessionInfo.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY);
if (attribute == null) {
continue;
}
sysUserEntity = (User) ((SimplePrincipalCollection) attribute).getPrimaryPrincipal();
if (sysUserEntity == null) {
continue;
}
if (Objects.equals(sysUserEntity.getUsername(), username)) {
session=sessionInfo;
// 清除该用户以前登录时保存的session，强制退出 -> 单用户登录处理
if (isRemoveSession) {
redisSessionDAO.delete(session);
}
}
}
if (session == null||attribute == null) {
return;
}
//删除session
if (isRemoveSession) {
redisSessionDAO.delete(session);
}
//删除Cache，再访问受限接口时会重新授权
DefaultWebSecurityManager securityManager = (DefaultWebSecurityManager) SecurityUtils.getSecurityManager();
Authenticator authc = securityManager.getAuthenticator();
((LogoutAware) authc).onLogout((SimplePrincipalCollection) attribute);
}
private static Session getSessionByUsername(String username){
// 获取当前已登录的用户session列表
Collection<Session> sessions = redisSessionDAO.getActiveSessions();
User user;
Object attribute;
// 遍历Session,找到该用户名称对应的Session
for(Session session : sessions){
attribute = session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY);
if (attribute == null) {
continue;
}
user = (User) ((SimplePrincipalCollection) attribute).getPrimaryPrincipal();
if (user == null) {
continue;
}
if (Objects.equals(user.getUsername(), username)) {
return session;
}
}
return null;
}
}2、Redis常量类
public interface RedisConstant {
String REDIS_PREFIX_LOGIN = "code-generator_token_%s";
}
3、Spring上下文工具类
@Component
public class SpringUtil implements ApplicationContextAware {
private static ApplicationContext context;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
context = applicationContext;
}
public static <T> T getBean(Class<T> beanClass) {
return context.getBean(beanClass);
}
