Redis based Tomcat Session Manager

Stores session of Apache Tomcat in Redis and allows to distribute requests across a cluster of Tomcat servers. Implements non-sticky session management backed by Redis.

Supports Apache Tomcat 6.x, 7.x, 8.x, 9.x

Advantages

Current implementation differs from any other Redis based Tomcat Session Manager in terms of efficient storage and optimized writes. Each session attribute is written into Redis during each HttpSession.setAttribute invocation. While other solutions serialize whole session each time.

Usage

1 Add RedissonSessionManager into context.xml

<Manager className="org.redisson.tomcat.RedissonSessionManager"
          configPath="${catalina.base}/redisson.conf" />

readMode - read attributes mode. Two modes are available: MEMORY and REDIS.
            MEMORY - read attributes stored in local Tomcat Session.
            REDIS - read directly from Redis.

configPath - path to Redisson JSON or YAML config. See configuration wiki page for more details.
