SpringBoot 中配置redis作为session 缓存器。让shiro引用

本文是建立在你是使用这shiro基础之上的补充内容

第一种：Redis缓存，将数据存储到redis 并且开启session存入redis中。

引入pom

org.springframework.boot spring-boot-starter-data-redis org.springframework.session spring-session-data-redis

配置redisConfig

@Configuration @EnableCaching public class RedisConfig extends CachingConfigurerSupport { @Bean public KeyGenerator keyGenerator() { return new KeyGenerator() { @Override public Object generate(Object target, Method method, Object... params) { StringBuilder sb = new StringBuilder(); sb.append(target.getClass().getName()); sb.append(method.getName()); for (Object obj : params) { sb.append(obj.toString()); } return sb.toString(); } }; } @Bean //在这里配置缓存reids配置 public RedisCacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) { RedisCacheConfiguration redisCacheCOnfiguration= RedisCacheConfiguration.defaultCacheConfig() .entryTtl(Duration.ofHours(1)); // 设置缓存有效期一小时 System.out.println("《========【开启redis】 ======== 》 "); return RedisCacheManager .builder(RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory)) .cacheDefaults(redisCacheConfiguration).build(); } @Bean public RedisTemplate redisTemplate(RedisConnectionFactory factory) { StringRedisTemplate template = new StringRedisTemplate(factory); Jackson2JsonRedisSerializer jackson2JsOnRedisSerializer= new Jackson2JsonRedisSerializer(Object.class); ObjectMapper om = new ObjectMapper(); om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY); om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL); jackson2JsonRedisSerializer.setObjectMapper(om); template.setValueSerializer(jackson2JsonRedisSerializer); template.afterPropertiesSet(); return template; } }

配置自定义缓存管理器，引入redis缓存管理器

定义自己的CacheManager

/** *

自定义cacheManage 扩张shiro里面的缓存使用reids作缓存

* * 引入自己定义的CacheManager * 关于CacheManager的配置文件在spring-redis-cache.xml中 * */ @Component public class ShiroSpringCacheManager implements CacheManager ,Destroyable{ /** * 将之上的RedisCacheManager的Bean拿出来注入于此 */ @Autowired private org.springframework.cache.CacheManager cacheManager; public org.springframework.cache.CacheManager getCacheManager() { return cacheManager; } public void setCacheManager(org.springframework.cache.CacheManager cacheManager) { this.cacheManager = cacheManager; } @Override public void destroy() throws Exception { cacheManager = null; } @Override public Cache getCache(String name) { if (name == null ){ return null; } // 新建一个ShiroSpringCache 将Bean放入并实例化 return new ShiroSpringCache(name,getCacheManager()); } }

定义自己实现的Shiro的Cache,实现了Shiro包里的Cache

/** *

自定义缓存将数据存入到redis中

*/ @SuppressWarnings("unchecked") public class ShiroSpringCache implements org.apache.shiro.cache.Cache{ private static final Logger log = LoggerFactory.getLogger(ShiroSpringCache.class); private CacheManager cacheManager; private Cache cache; public ShiroSpringCache(String name, CacheManager cacheManager) { if(name==null || cacheManager==null){ throw new IllegalArgumentException("cacheManager or CacheName cannot be null."); } this.cacheManager = cacheManager; //这里首先是从父类中获取这个cache,如果没有会创建一个redisCache,初始化这个redisCache的时候 //会设置它的过期时间如果没有配置过这个缓存的，那么默认的缓存时间是为0的，如果配置了，就会把配置的时间赋予给这个RedisCache //如果从缓存的过期时间为0，就表示这个RedisCache不存在了，这个redisCache实现了spring中的cache this.cache= cacheManager.getCache(name); } @Override public V get(K key) throws CacheException { log.info("从缓存中获取key为{}的缓存信息",key); if(key == null){ return null; } ValueWrapper valueWrapper = cache.get(key); if(valueWrapper==null){ return null; } return (V) valueWrapper.get(); } @Override public V put(K key, V value) throws CacheException { log.info("创建新的缓存，信息为：{}={}",key,value); cache.put(key, value); return get(key); } @Override public V remove(K key) throws CacheException { log.info("干掉key为{}的缓存",key); V v = get(key); cache.evict(key);//干掉这个名字为key的缓存 return v; } @Override public void clear() throws CacheException { log.info("清空所有的缓存"); cache.clear(); } @Override public int size() { return cacheManager.getCacheNames().size(); } /** * 获取缓存中所的key值 */ @Override public Set keys() { return (Set) cacheManager.getCacheNames(); } /** * 获取缓存中所有的values值 */ @Override public Collection values() { return (Collection) cache.get(cacheManager.getCacheNames()).get(); } @Override public String toString() { return "ShiroSpringCache [cache=" + cache + "]"; } }

到此为止，使用redis做缓存，和spring的集成就完成了。

可以使用以下注解将缓存放入redis

@Cacheable(value = Cache.CONSTANT, key = "'" + CacheKey.DICT_NAME + "'+#name+'_'+#val")

配置spring session管理器

@Bean @ConditionalOnProperty(prefix = "xpro", name = "spring-session-open", havingValue = "true") public ServletContainerSessionManager servletContainerSessionManager() { return new ServletContainerSessionManager(); }

新建类 spring session设置session过期时间

/** * spring session配置 * * @author xingri * @date 2017-07-13 21:05 */ @EnableRedisHttpSession(maxInactiveIntervalInSecOnds= 900) //session过期时间如果部署多机环境,需要打开注释 @ConditionalOnProperty(prefix = "xpro", name = "spring-session-open", havingValue = "true") public class SpringSessionConfig { }

第一种：Ehcache做缓存，可以将数据存储到磁盘中，也可以存到内存中

新建ehcache.xml 文件

配置自定义缓存管理器，引入ehcache缓存管理器

/** * ehcache配置 * */ @Configuration @EnableCaching public class EhCacheConfig { /** * EhCache的配置 */ @Bean public EhCacheCacheManager cacheManager(CacheManager cacheManager) { MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer(); ManagementService.registerMBeans(cacheManager, mBeanServer, true, true, true, true); return new EhCacheCacheManager(cacheManager); } /** * EhCache的配置 */ @Bean public EhCacheManagerFactoryBean ehcache() { System.out.println("《========【开启ehcache】 ======== 》 "); EhCacheManagerFactoryBean ehCacheManagerFactoryBean = new EhCacheManagerFactoryBean(); ehCacheManagerFactoryBean.setConfigLocation(new ClassPathResource("ehcache.xml")); return ehCacheManagerFactoryBean; } @Bean public org.apache.shiro.cache.CacheManager getCacheShiroManager(EhCacheManagerFactoryBean ehcache) { EhCacheManager ehCacheManager = new EhCacheManager(); ehCacheManager.setCacheManager(ehcache.getObject()); return ehCacheManager; } }

最后最重要的是引入shriro 中

/** * shiro权限管理的配置 * */ @Configuration public class ShiroConfig { /** * 安全管理器 */ @Bean public DefaultWebSecurityManager securityManager(COOKIERememberMeManager rememberMeManager, CacheManager cacheShiroManager, SessionManager sessionManager) { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setAuthenticator(modularRealmAuthenticator()); List realms=new ArrayList(); securityManager.setRealms(realms); securityManager.setCacheManager(cacheShiroManager); securityManager.setRememberMeManager(rememberMeManager); securityManager.setSessionManager(sessionManager); return securityManager; } /** * spring session管理器（多机环境） */ @Bean public ServletContainerSessionManager servletContainerSessionManager() { return new ServletContainerSessionManager(); } /** * session管理器(单机环境) 使用COOKIE存储缓存。。如果多级请注释 */ @Bean public DefaultWebSessionManager defaultWebSessionManager(CacheManager cacheShiroManager, XProProperties xProProperties) { DefaultWebSessionManager sessiOnManager= new DefaultWebSessionManager(); sessionManager.setCacheManager(cacheShiroManager); sessionManager.setSessionValidationInterval(xProProperties.getSessionValidationInterval() * 1000); sessionManager.setGlobalSessionTimeout(xProProperties.getSessionInvalidateTime() * 1000); sessionManager.setDeleteInvalidSessions(true); sessionManager.setSessionValidationSchedulerEnabled(true); COOKIE COOKIE = new SimpleCOOKIE(ShiroHttpSession.DEFAULT_SESSION_ID_NAME); COOKIE.setName("shiroCOOKIE"); COOKIE.setHttpOnly(true); sessionManager.setSessionIdCOOKIE(COOKIE); return sessionManager; } /** * 缓存管理器使用Ehcache实现如果使用redis则注释下面内容！！！！ */ @Bean public CacheManager getCacheShiroManager(EhCacheManagerFactoryBean ehcache) { EhCacheManager ehCacheManager = new EhCacheManager(); ehCacheManager.setCacheManager(ehcache.getObject()); return ehCacheManager; } /** * 项目自定义的Realm */ @Bean public ShiroDbRealm shiroDbRealm() { return new ShiroDbRealm(); } @Bean public ShiroTockenRealm shiroTockenRealm( ) { return new ShiroTockenRealm(); } @Bean public ShiroJwtRealm shiroJwtRealm( ) { return new ShiroJwtRealm(); } /** * 系统自带的Realm管理，主要针对多realm * */ @Bean public ModularRealmAuthenticator modularRealmAuthenticator(){ ModularRealmAuthenticator modularRealmAuthenticator=new ModularRealmAuthenticator(); modularRealmAuthenticator.setAuthenticationStrategy(new AtLeastOneSuccessfulStrategy()); return modularRealmAuthenticator; } /** * rememberMe管理器, cipherKey生成见{@code Base64Test.java} */ @Bean public COOKIERememberMeManager rememberMeManager(SimpleCOOKIE rememberMeCOOKIE) { COOKIERememberMeManager manager = new COOKIERememberMeManager(); manager.setCipherKey(Base64.decode("Z3VucwAAAAAAAAAAAAAAAA==")); manager.setCOOKIE(rememberMeCOOKIE); return manager; } /** * 记住密码COOKIE */ @Bean public SimpleCOOKIE rememberMeCOOKIE() { SimpleCOOKIE simpleCOOKIE = new SimpleCOOKIE("rememberMe"); simpleCOOKIE.setHttpOnly(true); simpleCOOKIE.setMaxAge(7 * 24 * 60 * 60);//7天 return simpleCOOKIE; } /** * 在方法中注入 securityManager,进行代理控制 */ @Bean public MethodInvokingFactoryBean methodInvokingFactoryBean(DefaultWebSecurityManager securityManager) { MethodInvokingFactoryBean bean = new MethodInvokingFactoryBean(); bean.setStaticMethod("org.apache.shiro.SecurityUtils.setSecurityManager"); bean.setArguments(new Object[]{securityManager}); return bean; } /** * 保证实现了Shiro内部lifecycle函数的bean执行 */ @Bean public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() { return new LifecycleBeanPostProcessor(); } /** * 启用shrio授权注解拦截方式，AOP式方法级权限检查 */ @Bean @DependsOn(value = "lifecycleBeanPostProcessor") //依赖其他bean的初始化 public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() { return new DefaultAdvisorAutoProxyCreator(); } @Bean public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(DefaultWebSecurityManager securityManager) { AuthorizationAttributeSourceAdvisor authorizatiOnAttributeSourceAdvisor= new AuthorizationAttributeSourceAdvisor(); authorizationAttributeSourceAdvisor.setSecurityManager(securityManager); return authorizationAttributeSourceAdvisor; } }
