JBossCache是一个复制的事务处理缓存，它允许你缓存企业级应用数据来更好的改善性能。缓存数据被自动复制，让你轻松进行Jboss服务器之间的集群工作。JBossCache能够通过Jboss应用服务或其他J2EE容器来运行一个Mbean服务，当然，它也能独立运行。 JBossCache包括两个模块：TreeCache和TreeCacheAOP。 TreeCache --是一个树形结构复制的事务处理缓存。 TreeCacheAOP --是一个“面向对象缓存，它使用AOP来动态管理POJO
官方提到：
"... the next major release of JBossCache, containing a whole host of new features, including: optimistic node locking (see wiki page); invalidation instead of replication; improved CacheLoader performance; ability to ‘chain’ more than one CacheLoader; a new ‘Options’ API, allowing configuration overriding on a per-invocation basis; a new ‘ClusterCacheLoader’ that treats a remotely running caches in the same cluster as a cache loader source; JDBCCacheLoader with improved compatibility with MySQL JDBC drivers; replication performance enhancements with JGroups 2.2.9; ‘Buddy’ replication – where state can just be replicated to a single other node in the cluster rather than broadcast to every node."
