使用参数 maxBytesLocalDisk 自定义 ehcache.xml 后引发异常

Question

现在我的应用程序使用 Ehcache、Hibernate 3.3.2GA、Spring 3.2.3.RELEASE。我想配置 ehcache，使缓存的 maxBytesLocalDisk 为 5GB。但它不起作用。搜索原因，发现Ehcache2.5只支持maxBytesLocalDisk。所以我从 ehcache 1.2.3 迁移到 2.5.0。 这是主项目的 pom.xml：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>3.3.2.GA</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-c3p0</artifactId>
    <version>3.6.3.Final</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-ehcache</artifactId>
    <version>3.3.2.GA</version>
    <exclusions>
    <!-- Excluding ehCache version 1.2.3 -->
        <exclusion>
            <artifactId>ehcache</artifactId>
            <groupId>net.sf.ehcache</groupId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>ejb3-persistence</artifactId>
    <version>3.3.2.Beta1</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>3.3.2.GA</version>
</dependency>
<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>2.5.0</version>
</dependency>

这是 cache.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cache="http://www.springframework.org/schema/cache"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.2.xsd">

<cache:annotation-driven cache-manager="cacheManager" />

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
    <property name="cacheManager">
        <bean class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
            <property name="configLocation" value="classpath:ehcache.xml" />
        </bean>
    </property>
</bean>
</beans>

这是 ehcache.xml：

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
    maxBytesLocalHeap="256m">
<diskStore path="/var/cache/tomcat7/ehcache"/>

<defaultCache eternal="false"
    overflowToDisk="true"
    memoryStoreEvictionPolicy="LFU"
    timeToIdleSeconds="0"
    timeToLiveSeconds="120" />

<cache name="cache1"
    overflowToDisk="true"
    maxBytesLocalDisk="5g"
    memoryStoreEvictionPolicy="LFU"
    timeToIdleSeconds="0"
    timeToLiveSeconds="3600" />

</ehcache>

重启托管此应用程序的tomcat后，抛出异常：

2014-04-26 08:47:50,211 7     ERROR [org.springframework.web.context.ContextLoader] (RMI TCP Connection(3)-127.0.0.1:) Context initialization failed

Initial cause was null:31: Element <cache> does not allow attribute "maxBytesLocalDisk".

我不知道这个错误是不是因为我在 pom.xml 上的设置。关于这个例外的任何想法？

我会检查你的依赖树。该错误似乎表明在类路径中仍发现旧的 Ehcache 版本。
