Session Timeout not applied for Redis backend #13721
Description
We observed the problem that despite configuring the Session timeout via spring.session.timeout the default of 30m/1800s was always active. Debugging we noticed, that SpringBootRedisHttpSessionConfiguration::customize() is not called even though RedisSessionConfiguration is properly matched for auto-configuration:
RedisSessionConfiguration matched:
- @ConditionalOnClass found required classes 'org.springframework.data.redis.core.RedisTemplate', 'org.springframework.session.data.redis.RedisOperationsSessionRepository'; @ConditionalOnMissingClass did not find unwanted class (OnClassCondition)
- Session Condition found spring.session.store-type property REDIS (ServletSessionCondition)
The following minimal setup application shows the issue:
