multicache4j - 为Java集成各种cache组件和ehcache

开发的一个项目，已在线上应用（多点应用+集群/主从复制），欢迎适用提建议

项目地址：http://code.google.com/p/multicache4j/

1.feature
multicache4j用于为Java集成各种cache组件：

方便集成各种remote cache
    memcached (支持组件spymemcached)
    memcachedb (支持组件spymemcached)
    ttserver (支持组件spymemcached, ttserverclient)
    redis (支持组件jedis)
方便集成各种local cache
    ehcache
基于对象池技术管理客户端连接对象，网络断开能够自动重连
基于Pattern Mapping进行哈希映射
支持remote cache和local cache的混合缓存
支持local cache的单独使用

2.usage

multi cache (remote + local, or remote , or local)：混合使用远程与本地Cache
适用场景：单点应用+集群Cache
MultiCacheFactory.getInstance().set("foo", "bar");MultiCacheFactory.getInstance().get("foo");

remote cache：单独使用远程Cache
适用场景：多点应用+集群Cache
RemoteCacheFactory.getInstance().set("foo", "bar");RemoteCacheFactory.getInstance().get("foo");

local cache：单独使用本地Cache
适用场景：单点应用/多点应用
LocalCacheFactory.getInstance().set("foo", "bar");LocalCacheFactory.getInstance().get("foo");

3.configuration
