springboot连接redis集群，我触发主从切换时报：

Connection to 172.23.7.168:6379 not allowed. This connection point is not known in the cluster view

springboot的配置：

spring:
  redis:
    cluster:
      nodes:
        - 172.23.209.33:6379
        - 172.23.62.194:6379
        - 172.23.151.243:6379
        - 172.23.64.167:6379
        - 172.23.14.224:6379
        - 172.23.115.119:6379
      max-redirects: 3
    lettuce:
      shutdown-timeout: 200ms
      pool:
        max-idle: 16
        max-active: 32
        min-idle: 8

新节点172.23.7.168:6379没在配置里，难道是这个原因嘛？

这是 Lettuce 的一项安全功能，目的是防止通过集群节点（CLUSTER NODES）重定向到（尚未）已知的节点。如果拓扑结构发生变化，而客户端有不同的视图，就会出现这种状态。

Redis在扩容/缩容过程中，当实例分片数发生变化时，存在节点拓扑关系和Slot对应信息的变化，需要客户端进行拓扑关系的自动更新，否则可能造成请求路由失败或者路由位置错误等，造成客户端访问报错。

1、开启Cluster集群自动刷新拓扑配置。

spring:
  redis:
    cluster:
      refresh:
        adaptive: true
        period: 30000    # 30秒自动刷新一次

2、关闭“验证集群节点成员资格开关”，关闭方式如下：

spring:
  redis:
    cluster:
      validate-cluster-node-membership: false
