Springboot整合SpringSession，解决分布式session共享问题 springboot整合SpringSession1、引入依赖<dependencies> <dependency> <groupId>org.springframework.session</groupId> <artifactId>spring-session-data-redis</artifactId> </dependency> </dependencies>2、springboot配置application.properties配置：保存类型spring.session.store-type=redis # Session store type.session过期时间：server.servlet.session.timeout= # Session timeout. If a duration suffix is not specified, seconds is used.其它配置信息可参考官网：spring.session.redis.flush-mode=on_save # Sessions flush mode. spring.session.redis.namespace=spring:session # Namespace for keys used to store sessions.连接信息配置：spring.redis.host=localhost # Redis server host. spring.redis.password= # Login password of the redis server. spring.redis.port=6379 # Redis server port.3、开启springSession主类加上注解@EnableRedisHttpSession@EnableRedisHttpSession4、使用注意：1、需要保存到redis中的数据必须序列化。2、需要实现session共享的微服务都必须整合SpringSession。5、解决子域session共享、cookie进行json序列化MySessionConfig配置package com.yanxizhu.family.booking.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer; import org.springframework.data.redis.serializer.RedisSerializer; import org.springframework.session.web.http.CookieSerializer; import org.springframework.session.web.http.DefaultCookieSerializer; /** * @description: springSession配置 * @author: <a href="mailto:batis@foxmail.com">清风</a> * @date: 2022/3/10 20:11 * @version: 1.0 */ @Configuration public class MySessionConfig { @Bean public CookieSerializer cookieSerializer(){ DefaultCookieSerializer defaultCookieSerializer = new DefaultCookieSerializer(); //设置共享域名 defaultCookieSerializer.setDomainName("yanxizhu.com"); //设置session名称 defaultCookieSerializer.setCookieName("YANXIZHUSESSION"); return defaultCookieSerializer; } //session序列化机制 @Bean public RedisSerializer<Object> springSessionDefaultRedisSerializer(){ return new GenericJackson2JsonRedisSerializer(); } }注意：需要session共享的微服务都需要配置，或者抽取到公共模块。6、多系统-session共享问题(单点登录)抽取单独的认证中心微服务处理单点登录单点登录，可参考一个开源单点登录项目，许雪里/xxl-sso
