This article introduces the relevant knowledge of "SpringBoot's method of integrating Redis". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Architecture

Scheme

Use redis centralized storage to achieve distributed clusters to share user information. Here, we use a third-party open source plug-in crazycake, and pom.xml introduces:

Org.springframework.boot spring-boot-starter-data-redis org.crazycake shiro-redis 3.2.3

Configure application.properties:

# Redis# database index (default is 0) redis.database=0# server address is changed to its own redis.host=127.0.0.1# server connection port redis.port=6379# server connection password. If you do not set the password to comment out, you can # redis.password=# connection timeout (milliseconds) redis.timeout=30000

Originally, the crazycake plug-in has implemented RedisManager, but the parameters are not matched. Here, we need to rewrite it ourselves:

Public class RedisManager extends WorkAloneRedisManager implements IRedisManager {private RedisProperties redis; private JedisPool jedisPool; public RedisManager (RedisProperties redis) {this.redis = redis } private void init () {synchronized (this) {if (this.jedisPool = = null) {this.jedisPool = new JedisPool (this.getJedisPoolConfig (), redis.getHost (), redis.getPort (), redis.getTimeout (), redis.getPassword (), redis.getDatabase ()) } @ Override protected Jedis getJedis () {if (this.jedisPool = = null) {this.init ();} return this.jedisPool.getResource ();}}

Parameter configuration RedisProperties:

@ Data@ConfigurationProperties (prefix = "redis") public class RedisProperties {private String host; private int port; private int timeout; private String password; private int database;}

Configure ShiroConfig:

/ * * Shiro permission configuration * be sure to configure @ Configuration and @ EnableConfigurationProperties annotations * / @ Configuration@EnableConfigurationProperties ({RedisProperties.class}) public class ShiroConfig {private RedisProperties redis; public ShiroConfig (RedisProperties redis) {this.redis = redis;} @ Bean public UserRealm userRealm () {return new UserRealm ();} @ Bean public ShiroFilterFactoryBean shiroFilterFactoryBean (SecurityManager securityManager) {ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean () ShiroFilterFactoryBean.setSecurityManager (securityManager); shiroFilterFactoryBean.setLoginUrl ("/ index.html"); shiroFilterFactoryBean.setUnauthorizedUrl ("/ 403"); / / interceptor Map filterChainDefinitionMap = new LinkedHashMap (); / * * static file * / filterChainDefinitionMap.put ("/ file/**", "anon") / * sign in and register * / filterChainDefinitionMap.put ("/ register.shtml", "anon"); filterChainDefinitionMap.put ("/ login.shtml", "anon"); / * * manage backend * / filterChainDefinitionMap.put ("/ sys/**", "roles [admin]") FilterChainDefinitionMap.put ("/ * *", "authc"); shiroFilterFactoryBean.setFilterChainDefinitionMap (filterChainDefinitionMap); return shiroFilterFactoryBean;} @ Bean public SessionsSecurityManager securityManager () {DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager (); securityManager.setRealm (userRealm ()); securityManager.setCacheManager (cacheManager ()); securityManager.setSessionManager (sessionManager ()); return securityManager } @ Bean public DefaultWebSessionManager sessionManager () {DefaultWebSessionManager sessionManager = new DefaultWebSessionManager (); sessionManager.setSessionIdUrlRewritingEnabled (false); sessionManager.setSessionDAO (redisSessionDAO ()); return sessionManager;} @ Bean public ShiroDialect shiroDialect () {return new ShiroDialect ();} / * cacheManager cache redis implementation * @ return * / public RedisCacheManager cacheManager () {RedisCacheManager redisCacheManager = new RedisCacheManager () RedisCacheManager.setRedisManager (redisManager ()); return redisCacheManager;} / * configure shiro redisManager * @ return * / public RedisManager redisManager () {RedisManager redisManager = new RedisManager (redis); return redisManager } / * * RedisSessionDAO shiro sessionDao layer implementation * principle is to rewrite AbstractSessionDAO * interested partners read the source code * / @ Bean public RedisSessionDAO redisSessionDAO () {RedisSessionDAO redisSessionDAO = new RedisSessionDAO (); redisSessionDAO.setRedisManager (redisManager ()); return redisSessionDAO;} this is the end of the introduction of "SpringBoot Integration Redis method".
