spring boot enable redis http session

17,269

This exception says that the application couldn't connect to the redis instance. Do you have a redis server running somewhere?

  1. Check your connection parameters in your configuration, that should solve the problem.
  2. Make sure the redis server is reachable by using the redis CLI ./redis-cli -h yourhost -p 6379 -a passwordIfNecessary

Note that the current spring-data-redis (one of the projects backing spring-session) requires redis 2.6+.

    I'm trying to use spring boots redis to store the sessions in it. When I follow their documentation, I always get an Exception when launching the server.

    What I've done so far: - I followed the documentation (click) added the needed dependency and created the pretty small config class => then I launched the server and I always get the following exception:

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'enableRedisKeyspaceNotificationsInitializer' defined in class path resource [org/springframework/session/data/redis/config/annotation/web/http/RedisHttpSessionConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
