yml配置：
spring:

cluster: #集群用这个配置
nodes: ${summary.redis.cluster.nodes}
max-redirects: 2 #获取失败 最大重定向次数

timeout: 60000
database: 0
lettuce:
pool:
max-active: 10 # 连接池最大连接数（使用负值表示没有限制）,如果赋值为-1，则表示不限制；如果pool已经分配了maxActive个jedis实例，则此时pool的状态为exhausted(耗尽)
max-idle: 8 # 连接池中的最大空闲连接 ，默认值也是8
max-wait: 100 # # 等待可用连接的最大时间，单位毫秒，默认值为-1，表示永不超时。如果超过等待时间，则直接抛出JedisConnectionException
min-idle: 2 # 连接池中的最小空闲连接 ，默认值也是0
shutdown-timeout: 100ms

hello ,doesn’t fix the issue anymore.
use 3.17.3+ version
我们也是，官方回复是网络问题。我这里降低了idel出现错误的概率降低了很多。还有修改redis服务端的tcp的keepalive时间短一点。都是会稍微好一些，还是偶尔会报错。崩溃了
