nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to 127.0.0.1/<unresolved>:6401

根据提供的引用内容，"nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to 127.0.0.1/<unresolved>:6401"是一个Redis连接异常的嵌套异常。解决这个问题的方法有以下几种：
1. 编辑redis.conf文件，可以使用vim命令打开/etc/redis.conf文件，检查Redis配置文件中的连接设置是否正确。
2. 在启动类上添加注解@SpringBootApplication(exclude = {RedisAutoConfiguration.class})，可以排除自动配置中的Redis相关配置，以避免连接异常的发生。
3. 如果已经存在@SpringBootApplication注解，可以叠加添加排除Redis自动配置的注解@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, RedisAutoConfiguration.class})。这样可以同时排除数据源和Redis的自动配置。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
