configuration - Ehcache 元素 不允许属性 "transactionalMode"？

Question

根据Ehcache documentation ，从 2.0 版本开始，一个 Ehcache 缓存可能会参与 JTA基于属性值的交易transactionalMode关于元素 <cache/> .

如果这是真的，那么为什么 Ehcache 在我的 Ehcache 配置文件中遇到此属性时，会抛出以下异常并提示“元素不允许属性“transactionalMode”。”:

Caused by: net.sf.ehcache.CacheException: Error configuring from zip:C:/Program Files/Oracle/Middleware/user_projects/domains/abstrack1/servers/AdminServer/tmp/_WL_user/_appsdir_middleware-ear-1.0-SNAPSHOT_ear/n8rga7/middleware-ejb-1.0-SNAPSHOT.jar!/ehcache.xml. Initial cause was Error configuring from input stream. Initial cause was null:35: Element <cache> does not allow attribute "transactionalMode".

这是我的 ehcache.xml 中的示例缓存定义我在其中设置的文件 transactionalMode到“xa”:

<cache
    name="com.db.spgit.abstrack.model.Security"
    maxElementsInMemory="500"
    eternal="false"
    timeToIdleSeconds="300"
    timeToLiveSeconds="86400"
    overflowToDisk="false"
    transactionalMode="xa" />

原来 Maven 也包含了 Ehcache 1.2.3在我的项目 EAR 文件中，因为 Hibernate Ehcache Integration 3.3.2.GA需要 Ehcache 1.2.3。
