一.问题 redis起来后一直有重连的日志,如下图: 二.分析参考lettuce-core的github上Issues解答https://github.com/lettuce-io/lettuce-core/issues/861 可知,这是lettuce-core的实现里,有类似心跳机制的保持长连接方式,不过心跳机制是不停的来回发心跳包直到连接不可用再去被动重新连接,而lettuce的方案是将连接池里处于空闲(idle)状态的client每隔一段时间就主动断开,然后再重新连接. 三.解决其实…

spring boot 中使用redis session

spring boot 默认的httpsession是存在内存中.这种默认方式有几个缺点:1.当分布式部署时,存在session不一致的问题:2.当服务重启时session就会丢失,这时候用户就需要重新登陆,可能导致用户数据丢失.通常会使用redis来保存session. 在spring boot中利用redis来保存session是非常简单.只需要简单的几步就可以了.可以参考官方教程.https://docs.spring.io/spring-session/docs/current/refe…

SpringBoot之使用Lettuce集成Redis

一.Lettuce Redis这里就不多说,服务端的启动之前的博客里面也有提到,这里略过.Lettuce和Jedis都是连接Redis Server的客户端程序,Jedis在实现上是直连redis server,多线程环境下非线程安全,除非使用连接池,为每个Jedis实例线程间并发访问,且线程安全,满足多线程环境下的并发访问,同时它是可伸缩的设计,一个连接实例不够的情况也可以按需增加连接实例. 二.maven依赖还是按照原来的步骤,先是导入依赖,然后配置属性,最后实例,其实使用springbo…
