解决方式

  • Redis未正常在运行,异常终止,或者启动失败
  • 未正确在程序里配置连接ip端口参数,例如ip错误使用localhost,又不在一台机器上
  • 检查程序服务于redis之间的网络是否联通,是否存在明显延迟
  • 可以修改Spring redis配置参数,增加连接超时时间
  • 检查服务器情况,确保内存和磁盘空间充足,检查已使用内存、剩余内存、已使用磁盘、剩余磁盘等
  • 简单来说,你的服务对redis的使用频率,如果读写很高很频繁、数据内容很多,就提供比较好的服务器,或者搭建redis集群
  • 也可以优化Spring redis配置参数,增加最大线程数、空闲线程数、连接超时时间等
  • 如果比较大的集合对象在redis存取,会占用很多内存,高并发情况下,可能做不到及时响应,可以只缓存必要的字段属性
  • 大量的key值,同时加到redis里面,又在一段时间后同时失效,造成瞬时压力过大,这要在业务上做一些随机失效时间
