Redis集群，把其中一台的服务停了，不会跳过它，从而导致页面报错？

[45592858]

版本号：

3.6.2

问题描述：

我的配置如下，是不是配置有问题？

redis: cluster: nodes: - 192.168.0.149:6379 - 192.168.0.140:6379 - 192.168.0.147:6379 jedis: pool: max-active: 10 max-idle: 5 min-idle: 2 max-wait: 1000

jeecg默认使用的是lettuce作为redis客户端的集群代理，另外jedis不支持自动刷新redis集群信息，只能手动刷新，只有lettuce才支持

可使用该配置自动清理失效集群实例

spring:
  redis:
    lettuce:
      cluster:
        refresh:
          adaptive: true  # 自适应刷新拓扑
