Redis 中的范围查询 - Spring Data Redis [英] Range Querying in Redis - Spring Data Redis

问题描述

有没有办法使用 Spring Data Redis 在 Redis 中实现 Range 查询?

is there a way we can implement Range queries in Redis using Spring Data Redis?

例如:

如果我的 Pojo 类具有日期(它不是主键)并且我需要落在所需日期范围内的数据，是否可以使用 Spring Data Redis 构建相同的查询而不是单独查询每个日期?

If my Pojo class has Date(which is not a primary key) and i require data that falls under a desired period of date, Is it possible with Spring Data Redis to construct a query for the same rather than querying each date individually?

推荐答案

对于 Redis ZSets，您有 ZSetOperations 接口，其中包含多个范围命令(请参阅 https://docs.spring.io/spring-data/redis/docs/2.5.1/api/org/springframework/data/redis/connection/RedisZSetCommands.html)，主要是:

For Redis ZSets you have ZSetOperationsinterface that have several range commands (see see https://docs.spring.io/spring-data/redis/docs/2.5.1/api/org/springframework/data/redis/connection/RedisZSetCommands.html), the main one being:

range(K key, long start, long end)

另外，还有几个 rangeByXXX.

如果您想要更强大的查询，我建议您查看 RediSearch (https://oss.redislabs.com/redisearch/).这里有 Spring 集成 https://oss.redislabs.com/redisearch/
