redis的模糊检索有两种方式:1、使用keys通配符 * ? []其匹配的字符跟一般的正则一样。keys a* 可以匹配以a开头的字符串。keys语法简单,但是数据量大的时候容易出现超时异常。2、使用scan这里使用的是spring的一个模板redisTemplateprivate Cursor<String> scan(String pattern, int limit) { ...

The key patterns specified with this flag will be found using SCAN. Use this option if you need glob pattern matching; check-single-keys is faster for non-pattern keys. Warning: using --check-keys to match a very large number of keys can slow down the exporter to the point where it ...
