错误原因：redis连接池lettuce存在bug
解决办法：更换连接池，使用jedis
org.springframework.boot spring-boot-starter-data-redis redis.clients jedis lettuce-core io.lettuce redis.clients jedis org.apache.commons commons-pool2
redis: host: 192.168.100.211 port: 6379 password: Ecourse4321 timeout: 3000 jedis: pool: max-active: 8 max-wait: 2000 max-idle: 8 min-idle: 0 time-between-eviction-runs: 1000
