spring - Ehcache 不允许持久化元素

Question

我使用的是 Ehcache 版本 2.7

pom.xml

<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>2.7.0</version>
</dependency>

context-cache.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:cache="http://www.springframework.org/schema/cache"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/cache 
    http://www.springframework.org/schema/cache/spring-cache.xsd">

<!-- generic cache manager -->
<cache:annotation-driven />

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"
 p:cacheManager-ref="ehcache"/>

<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
    p:configLocation="classpath:ehcache.xml" p:shared="true" />

ehcache.xml

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" updateCheck="true"
monitoring="autodetect" dynamicConfig="true">   

    <defaultCache eternal="true" maxElementsInMemory="100" overflowToDisk="false" />
    <cache name="AC" maxElementsInMemory="50000" eternal="true" overflowToDisk="false">
        <persistence strategy="localRestartable" synchronousWrites="false" />
    </cache>

</ehcache>

我收到以下异常

org.xml.sax.SAXException: null:9: Element <cache> does not allow nested <persistence> elements.

即使 http://ehcache.org/ehcache.xsd

允许这样做

<xs:element minOccurs="0" maxOccurs="1" ref="persistence"/>

我不知道是什么导致了这个问题，以及为什么 SAX 提示 persistence 不允许。我做错了什么？

原来我在 pom.xml 中加载了休眠 ehcache，这与 ehcache 2.7.0 冲突。删除该依赖项后，一切正常。再花 4 个小时就值得了 :(
