Error: spring.cache.redis.time-to-live not working

What's Causing This Error

The error message 'spring.cache.redis.time-to-live not working' suggests that there is an issue with the time-to-live (TTL) configuration of Redis cache in a Spring application. TTL defines the amount of time for which Redis should keep a particular key-value pair in cache before it expires and gets evicted automatically. There are several potential reasons why the TTL configuration may not be working as expected:

  1. Incorrect configuration: The TTL value may not have been set correctly in the Spring cache configuration file, or there could be a typo or formatting issue in the configuration.

  2. Incompatible Redis version: The Redis version being used with the Spring application may not support TTL expiration or may have different syntax for setting TTL.

  3. Caching framework issues: If the Spring caching framework being used is not compatible with Redis or has bugs related to TTL, it can cause issues with TTL settings.

Solution - Here's How To Resolve It

To resolve the 'spring.cache.redis.time-to-live not working' error, you can take the following steps:

  1. Check the Spring cache configuration file to ensure that the TTL value is set correctly and there are no formatting or syntax issues. You should also verify that the correct Redis version is being used.

  2. Try using a different Redis client library or upgrading to the latest version of the library to see if it resolves the issue. Alternatively, you can try downgrading to an earlier version if the latest version is causing compatibility issues.

  3. If all else fails, consider switching to a different caching framework that is known to work well with Redis. For example, you can try using the Jedis or Lettuce libraries instead of Spring cache. Additionally, you may want to consult the Redis documentation or seek help from the Redis community to troubleshoot any further issues.
