Springmvc中配置ehcache遇到錯誤Another CacheManager with same name

Caused by: net.sf.ehcache.CacheException: Another CacheManager with same name '' 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.
The source of the existing CacheManager is: DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]

這個錯誤在windows的tomcat裏，沒有顯示；但是部署到linux系統之後，就出現了，導致無法正常啓動！下面是解決方案

這個是ehcache 配置問題

<!-- Ehcache library setup -->
    <bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" p:shared="true"/>
