Question

根据Ehcache documentation，从版本2.0开始，Ehcache缓存可以根据元素transactionalMode上的属性<cache/>的值参与JTA事务。< / p>

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抱怨“Element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".

以下是我的ehcache.xml文件中的示例缓存定义，其中我将transactionalMode设置为“xa”：

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

Answer 1

事实证明，Maven还在我的项目EAR文件中包含了Ehcache 1.2.3，因为Hibernate Ehcache Integration 3.3.2.GA需要Ehcache 1.2.3。

Answer 2

这意味着您需要删除传递依赖关系ehcache 1.2.3.jar并保留include 2.X版本。需要看看是否在使用hibernate 3.2.X时没有问题。

Ehcache元素<cache>不允许属性“transactionalMode”？</cache>
