2.问题原因

  • 可能是Redis服务长时间处于高并发情况，或服务异常断链
  • 它表示Redis命令超时了。嵌套异常io.lettuce.core.RedisCommandTimeoutException指出具体的Redis命令超时异常细节。根据异常信息，这个Redis命令在1分钟后超时了，可能是由于Redis服务器太忙或者网络延迟等原因导致的。为了解决这个问题，可以尝试增加Redis服务器的性能、优化Redis命令或者调整系统配置来提高网络稳定性，以减少超时的概率。

3.解决方法

  1. 增加Redis服务器的性能：可以通过增加Redis服务器的内存、CPU和网络带宽等资源来提高其性能，从而减少Redis命令超时的概率。
  2. 优化Redis命令：可以检查应用程序中使用的Redis命令是否存在性能瓶颈，并尝试进行优化。例如，可以减小Redis数据集的大小，或者使用更有效的Redis命令（例如使用SCAN命令代替KEYS命令）。
  3. 调整系统配置以提高网络稳定性：如果超时是由于网络延迟或不稳定性导致的，则可以尝试调整系统配置来提高网络稳定性，例如增加网络带宽、减小TCP超时时间等。
  4. 使用合适的Redis客户端库：可以考虑使用性能更好、更稳定的Redis客户端库，例如Jedis或Lettuce。这些客户端库通常具有更好的错误处理功能，并且能够更好地处理Redis命令超时等异常情况。
