SpringBoot整合Redis的方法

SpringBoot整合Redis的方法

本篇内容介绍了“SpringBoot整合Redis的方法”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

架构

方案

使用redis集中存储，实现分布式集群共享用户信息，这里我们采用第三方开源插件crazycake来实现，pom.xml引入：

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>org.crazycake</groupId><artifactId>shiro-redis</artifactId><version>3.2.3</version></dependency>

配置application.properties：

#Redis#数据库索引（默认为0）redis.database=0#服务器地址变更为自己的redis.host=127.0.0.1#服务器连接端口redis.port=6379#服务器连接密码，如果不设置密码注释掉即可#redis.password=#连接超时时间（毫秒）redis.timeout=30000

本来crazycake插件已经实现了RedisManager，但是参数不可配，这里我们需要自己重写一下：

publicclassRedisManagerextendsWorkAloneRedisManagerimplementsIRedisManager{privateRedisPropertiesredis;privateJedisPooljedisPool;publicRedisManager(RedisPropertiesredis){this.redis=redis;}privatevoidinit(){synchronized(this){if(this.jedisPool==null){this.jedisPool=newJedisPool(this.getJedisPoolConfig(),redis.getHost(),redis.getPort(),redis.getTimeout(),redis.getPassword(),redis.getDatabase());}}}@OverrideprotectedJedisgetJedis(){if(this.jedisPool==null){this.init();}returnthis.jedisPool.getResource();}}

参数配置RedisProperties：

@Data@ConfigurationProperties(prefix="redis")publicclassRedisProperties{privateStringhost;privateintport;privateinttimeout;privateStringpassword;privateintdatabase;}

配置ShiroConfig：

/***Shiro权限配置*一定要配置@Configuration和@EnableConfigurationProperties注解*/@Configuration@EnableConfigurationProperties({RedisProperties.class})publicclassShiroConfig{privateRedisPropertiesredis;publicShiroConfig(RedisPropertiesredis){this.redis=redis;}@BeanpublicUserRealmuserRealm(){returnnewUserRealm();}@BeanpublicShiroFilterFactoryBeanshiroFilterFactoryBean(SecurityManagersecurityManager){ShiroFilterFactoryBeanshiroFilterFactoryBean=newShiroFilterFactoryBean();shiroFilterFactoryBean.setSecurityManager(securityManager);shiroFilterFactoryBean.setLoginUrl("/index.html");shiroFilterFactoryBean.setUnauthorizedUrl("/403");//拦截器Map<String,String>filterChainDefinitionMap=newLinkedHashMap<>();/***静态文件*/filterChainDefinitionMap.put("/file/**","anon");/***登录注册*/filterChainDefinitionMap.put("/register.shtml","anon");filterChainDefinitionMap.put("/login.shtml","anon");/***管理后台*/filterChainDefinitionMap.put("/sys/**","roles[admin]");filterChainDefinitionMap.put("/**","authc");shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);returnshiroFilterFactoryBean;}@BeanpublicSessionsSecurityManagersecurityManager(){DefaultWebSecurityManagersecurityManager=newDefaultWebSecurityManager();securityManager.setRealm(userRealm());securityManager.setCacheManager(cacheManager());securityManager.setSessionManager(sessionManager());returnsecurityManager;}@BeanpublicDefaultWebSessionManagersessionManager(){DefaultWebSessionManagersessionManager=newDefaultWebSessionManager();sessionManager.setSessionIdUrlRewritingEnabled(false);sessionManager.setSessionDAO(redisSessionDAO());returnsessionManager;}@BeanpublicShiroDialectshiroDialect(){returnnewShiroDialect();}/***cacheManager缓存redis实现*@return*/publicRedisCacheManagercacheManager(){RedisCacheManagerredisCacheManager=newRedisCacheManager();redisCacheManager.setRedisManager(redisManager());returnredisCacheManager;}/***配置shiroredisManager*@return*/publicRedisManagerredisManager(){RedisManagerredisManager=newRedisManager(redis);returnredisManager;}/***RedisSessionDAOshirosessionDao层的实现*原理就是重写AbstractSessionDAO*有兴趣的小伙伴自行阅读源码*/@BeanpublicRedisSessionDAOredisSessionDAO(){RedisSessionDAOredisSessionDAO=newRedisSessionDAO();redisSessionDAO.setRedisManager(redisManager());returnredisSessionDAO;}
