EHCache loadAndCorrectConfiguration NPE

Question

Я пытаюсь использовать ehcache с hibernate / spring. Моя попытка бросить NPE.

Я застрял на этом. И, гуглить не поможет.

Caused by: java.lang.NullPointerException

Вот моя весенняя конфигурация:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="myDataSource"/>
    <property name="annotatedClasses">
        <list>
            <value>com.agriserver.domain.AaFriend</value>
        </list>
    </property>
<property name="hibernateProperties">
    <props>
        <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
        <prop key="hibernate.show_sql">true</prop>

        <!-- Enable EHCache -->
        <prop key="hibernate.cache.use_second_level_cache">true</prop>
        <prop key="hibernate.cache.use_query_cache">false</prop>
        <prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</prop>
        <prop key="net.sf.ehcache.configurationResourceName">/ehcache.xml</prop>
    </props>
</property>

Вот файл ehcache.xml:

<?xml version="1.0" encoding="UTF-8"?>

<ehcache>
    <diskStore path="java.io.tmpdir"/>

    <cache
            name="com.agriserver.domain.AaFriend"
            maxElementsInMemory="10"
            maxElementsOnDisk="1000"
            eternal="false"
            timeToIdleSeconds="300"
            timeToLiveSeconds="600"
            overflowToDisk="true"
            />

    <cache
            name="org.hibernate.cache.StandardQueryCache"
            maxElementsInMemory="1"
            eternal="false"
            timeToLiveSeconds="120"
            overflowToDisk="false"/>
</ehcache>

Какие-нибудь советы?

Answer 1

Похоже, что проблема исчезла, добавив нижеприведенный файл в ehcache.xml.Странно, потому что я скопировал и вставил свой ehcache.xml из раздела «Начало работы» сайта ehcacheИ у него не было этого раздела:

<defaultCache
        maxElementsInMemory="10000"
        eternal="false"
        timeToIdleSeconds="120"
        timeToLiveSeconds="120"
        overflowToDisk="true"
        maxElementsOnDisk="10000000"
        diskPersistent="false"
        diskExpiryThreadIntervalSeconds="120"
        memoryStoreEvictionPolicy="LRU"
        />
