Package org.javalite.activejdbc.cache

Class RedisCacheManager

java.lang.Object

org.javalite.activejdbc.cache.CacheManager

org.javalite.activejdbc.cache.RedisCacheManager

public class RedisCacheManager
extends CacheManager

Redis cache manager. Will store caches in Redis server. By default will connect to Redis running on local host.

If redis server is located elsewhere, provide property files for different environments according to AppConfig rules. See: AppConfig for more information. The environment-specific properties files have to have the following properties for this class to function:

• redis.cache.manager.host
• redis.cache.manager.port

If the properties or property files are missing, this class will default to localhost and default port for Redis.

Limitation: Does not support CacheManager.flush(CacheEvent) with value 'ALL'.
