我在使用ehcache和Spring启动tomcat时收到此错误。

Another CacheManager with same name 'cacheManager' already exists in the same VM. Please 
provide unique names for each CacheManager in the config or do one of following:
1. Use one of the CacheManager.create() static factory methods to reuse same
   CacheManager with same name or create one if necessary
2. Shutdown the earlier cacheManager before creating new one with same name.

• Spring3.1
• Ehcache 2.9.0版本
• 没有使用此的测试上下文。
• 这是Web JSF应用程序。

ehcache.xml

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

    </ehcache>

cache-context.xml

<bean id="cacheManager" 

        class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" scope="singleton">
                <property name="shared" value="true"/>
                <property name="configLocation">
                    <value>classpath:ehcache.xml</value>
                </property>
            </bean>

我有一个老的依赖hibernate-ehcache，不幸的是，我不能删除。这是问题吗？

<dependency>
                   <groupId>org.hibernate</groupId>
                   <artifactId>hibernate-ehcache</artifactId>
                   <version>3.5.0-Final</version>
               </dependency>

有什么建议吗？谢谢！
