Springboot 2.6集成redis maven报错

<dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-data-redis</artifactId>        </dependency>

当加这个配置后，POM.xml的第一行总是报错：

看了意思是获取不到最新包，因为maven之前已经下载过，需要删除m2库里的最新玩意，

找到自己仓库，我的是C:\users\ckw\.m2\repository>,

在这个目录下，打开cmd，执行：

for /r %i in (*.lastUpdated) do del %i

执行这个批处理，

SpringBoot集成Redis连接不上

问题描述

初学SpringBoot

当进行SpringBoot集成Redis时。测试向redis中添加String类型的数据，key=name , value = zlw。

但出现了一下错误：（Whitelabel Error Page）

看控制台输出发现，大致应该是redis没有连接成功。

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.redis.RedisConnectionFailureException: Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to 192.168.86.129/<unresolved>:6379] with root cause

上网搜索了好多这个问题的错误，但好像都没有解决，不是自己的错误，但后来回想到，学习linux的时候，想要连接成功必须要关闭linux的防火墙才行。。。

试一试
