该怎么解决呢

看最后一个报错，是你redis 密码没设置吧

Caused by: io.lettuce.core.RedisCommandExecutionException: NOAUTH Authentication required.

不能连接到 localhost/:6379 的redis，看看你的配置文件。正常本地地址是 localhost 或者 127.0.0.1，端口是6379

没设置redis密码？或者设置密码没重启服务吧

不知道你这个问题是否已经解决, 如果还没有解决的话:

• 这个问题的回答你可以参考下: https://ask.csdn.net/questions/748611
• 这篇博客你也可以参考下：在Springboot启动redis的时候遇上的问题，以及配置redis的环境变量
• 除此之外, 这篇博客: springboot项目引入redis数据库中的 springboot项目引入redis数据库 部分也许能够解决你的问题, 你可以仔细阅读以下内容或者直接跳转源博客中阅读:
  

  准备工作：必须有redis，我这边是本机测试，redis直接安装在本机的，在进行下列操作之前要在本机开启redis并让其一直处于运行状态

  引入组件三部曲：导依赖，设配置，运用
• 您还可以看一下 张通老师的漫谈SpringBoot之入门到精通课程中的 SpringBoot与Redis集成小节, 巩固相关知识点
  

如果你已经解决了该问题, 非常希望你能够分享一下解决方案, 写成博客, 将相关链接放在评论区, 以帮助更多的人 ^-^

• 确保你redis 可以正常启动

• 检查 springboot配置文件中 是否配置 redis相关参数

• 检查 redis 设置密码 ，如果设置 在springboot配置中添加

注意⚠️ 检查你的 pom.xml redis 检查jar 是否存在版本不兼容问题
