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
|
|
|
|
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`
|
|
|
|
```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](https://github.com/redisson/redisson/wiki/2.-Configuration) for more details.
|
|
|
|
|
|
**2** Copy two jars into `TOMCAT_BASE/lib` directory:
