@TonyLuo : Could you please give some more information on how to reproduce this error. Maybe fill the issue template by including the .yo-rc.json file and any entity configurations you've created. :smile:

cc @Shaolans as he's the one who coded initially the Redis cache

I will investigate ASAP !

Hello, sorry for the late reply.
I tried to reproduce your issue, however it seems to be working fine.
When I call clearUserCaches, the usersByLogin is cleared.
Have you updated the generator to the 6.7.X ? Because the method clearUserCaches is different from what I have generated.

public void clearUserCaches(User user) {
        Objects.requireNonNull(cacheManager.getCache(UserRepository.USERS_BY_LOGIN_CACHE)).evict(user.getLogin());
        if (user.getEmail() != null) {
            Objects.requireNonNull(cacheManager.getCache(UserRepository.USERS_BY_EMAIL_CACHE)).evict(user.getEmail());
        }
    }

[TonyLuo]

thanks for reply. I did upgrade to 6.7.X.
I just removed following code as our application didn't need it:
if (user.getEmail() != null) { Objects.requireNonNull(cacheManager.getCache(UserRepository.USERS_BY_EMAIL_CACHE)).evict(user.getEmail()); }

[Shaolans]

Since your issue does not appear with the app I generated with your .yo-rc.json, can you give me more details on how to reproduce it with minimal changes ?
