传统捞项目基于servlet容器 cookie单体会话改造分布式会话方案
##引入redis,spring-session依赖
<!--redis依赖 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>org.springframework.session</groupId><artifactId>spring-session-data-redis</artifactId></dependency>##修改配置文件

@EnableRedisHttpSession(redisNamespace = "yym:session", maxInactiveIntervalInSeconds = 3600)
##原理
##spring自动配置spring.factories
##生成SessionRepositoryFilter过滤器对象
##使用包装的SessionRepositoryRequestWrapper的request SessionRepositoryResponseWrapper的response
