org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'redisConnectionFactory' defined in class path resource [org/springframework/boot/autoconfigure/data/redis/LettuceConnectionConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory]: Factory method 'redisConnectionFactory' threw exception; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/pool2/impl/GenericObjectPoolConfig
报创建Bean异常，看到最后一句java.lang.NoClassDefFoundError: org/apache/commons/pool2/impl/GenericObjectPoolConfig，意思就是少了个依赖，在pom文件中添加一下指定依赖就好了
比如这一句，需要添加如下依赖
org.apache.commons commons-pool2
然后添加完成后重新启动一下就好，启动前最好将之前打的包clean一下，要不有时候还是会报错
