Error: spring boot redis cache not working

What's Causing This Error

The error message 'spring boot redis cache not working' indicates that there is an issue with the Redis caching system in a Spring Boot application. There could be several reasons behind this issue, including incorrect configuration settings, network connectivity issues, or Redis server-related problems.

One possible cause of this error is that the Redis server is not running or is not accessible from the application. Another cause could be misconfigured connection settings such as incorrect host, port, or password. Additionally, it could be caused by Redis not being properly integrated into the Spring Boot application or a problem with the Redis driver that is used.

Solution - Here's How To Resolve It

To resolve the 'spring boot redis cache not working' error, there are several solutions to consider:

  1. Verify Redis Server: Check whether the Redis server is up and running, confirm its IP address, port number, and authentication credentials. Ensure that the Redis server is reachable from the application by pinging it or using telnet.
  2. Check Redis Configuration: Check your Spring Boot application's configuration file (e.g., or application.yml) to ensure that the Redis configuration properties are correctly set. Make sure the Redis host, port, and any authentication details are accurate.
  3. Check Cache Annotations: Review the usage of cache-related annotations (@Cacheable, @CachePut, @CacheEvict, etc.) in your code. Make sure they are correctly applied to the methods or classes you want to cache. Verify the cache names or keys used in the annotations as well.
  4. Confirm Spring Boot Dependency: Verify that the Spring Boot project has the appropriate Redis dependencies. The correct version of lettuce-core driver should be included in the project classpath.
  5. Debug Redis Driver: If the previous steps do not rectify the issue, consider debugging the Redis driver. Try upgrading or downgrading the Redis driver to see if it fixes the error, or switch to a different driver if necessary.
  6. Enable Redis Logging: Enable Redis logging by configuring the log level of Redis connection factory logs to DEBUG. This can help identify the root cause of the issue by providing relevant information about the Redis connection process.

By following these solutions, it should be possible to identify and rectify the underlying cause of the error and get Redis caching working in a Spring Boot application.
