基础整合步骤

1. 配置SecurityManager

@Configuration public class ShiroConfig { @Bean public SecurityManager securityManager(Realm realm) { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setRealm(realm); securityManager.setRememberMeManager(rememberMeManager()); return securityManager; } } 

2. 配置ShiroFilter

@Bean public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager) { ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean(); factoryBean.setSecurityManager(securityManager); Map<String, String> filterChainMap = new LinkedHashMap<>(); filterChainMap.put("/static/**", "anon"); filterChainMap.put("/login", "anon"); filterChainMap.put("/**", "authc"); factoryBean.setFilterChainDefinitionMap(filterChainMap); factoryBean.setLoginUrl("/login"); factoryBean.setSuccessUrl("/dashboard"); return factoryBean; } 

3. 启用AOP支持

@Bean public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor( SecurityManager securityManager) { AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor(); advisor.setSecurityManager(securityManager); return advisor; }

领域配置详解

自定义Realm示例

public class CustomRealm extends AuthorizingRealm { @Autowired private UserService userService; @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token) throws AuthenticationException { UsernamePasswordToken upToken = (UsernamePasswordToken) token; User user = userService.findByUsername(upToken.getUsername()); if(user == null) { throw new UnknownAccountException("用户不存在"); } return new SimpleAuthenticationInfo( user.getUsername(), user.getPassword(), ByteSource.Util.bytes(user.getSalt()), getName() ); } @Override protected AuthorizationInfo doGetAuthorizationInfo( PrincipalCollection principals) { // 授权逻辑实现 } } 

---

过滤器链配置

常用过滤器类型

过滤器名	描述
anon	匿名访问
authc	需要认证
user	记住我用户可访问
perms	需要权限
roles	需要角色

动态URL权限配置

@Bean public FilterChainDefinitionMap filterChainDefinitionMap() { PathMatchingFilterChainDefinition chainDefinition = new PathMatchingFilterChainDefinition(); // 从数据库加载动态权限 List<Permission> permissions = permissionService.getAll(); permissions.forEach(p -> { chainDefinition.addPathDefinition( p.getUrl(), "perms[" + p.getCode() + "]" ); }); return chainDefinition; } 

---

会话管理

分布式会话配置

@Bean public SessionManager sessionManager() { DefaultWebSessionManager sessionManager = new DefaultWebSessionManager(); sessionManager.setSessionDAO(redisSessionDAO()); sessionManager.setSessionIdCookie(sessionIdCookie()); sessionManager.setGlobalSessionTimeout(1800000); // 30分钟 return sessionManager; } @Bean public SessionDAO redisSessionDAO() { RedisSessionDAO dao = new RedisSessionDAO(); dao.setRedisManager(redisManager()); dao.setExpire(1800); return dao; } 

---

缓存整合

Ehcache配置示例

<!-- shiro-ehcache.xml --> <ehcache> <diskStore path="java.io.tmpdir/shiro-spring-sample"/> <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false"/> </ehcache> 

Redis缓存管理器

@Bean public CacheManager cacheManager() { RedisCacheManager cacheManager = new RedisCacheManager(); cacheManager.setRedisManager(redisManager()); cacheManager.setExpire(3600); return cacheManager; } 

---

注解支持

启用注解

@Configuration @EnableAspectJAutoProxy public class AopConfig { @Bean public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() { return new LifecycleBeanPostProcessor(); } } 

常用注解

@RequiresAuthentication public void sensitiveOperation() { // 需要认证 } @RequiresPermissions("user:delete") public void deleteUser() { // 需要权限 } @RequiresRoles("admin") public void adminOperation() { // 需要角色 } 

---

常见问题解决

1. 循环依赖问题

// 使用@Lazy解决 @Bean public SecurityManager securityManager(@Lazy Realm realm) { // ... } 

2. 静态资源被拦截

filterChainMap.put("/assets/**", "anon"); filterChainMap.put("/favicon.ico", "anon"); 

3. 权限缓存不更新

@Bean public Realm realm() { CustomRealm realm = new CustomRealm(); realm.setCachingEnabled(true); realm.setAuthenticationCachingEnabled(false); return realm; } 

---

最佳实践

1. 分离配置：将Shiro配置与业务配置分离
2. 使用自定义Filter：处理特殊认证需求
3. 实现动态权限：结合数据库实现实时权限更新
4. 会话持久化：生产环境必须配置持久化方案
5. 监控集成：通过JMX暴露Shiro指标

性能优化建议

• 启用授权缓存
• 合理设置会话超时
• 避免频繁调用权限检查
• 使用高效的SessionDAO实现
