ehcache cacheManager重複的問題

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ehcache' defined in class path resource [applicationContext-ehcache.xml]: Invocation of init method failed; nested exception is net.sf.ehcache.CacheException: Another unnamed 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.
The source of the existing CacheManager is: DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]

在應用中，自己封裝了ehcache，同時又使用spring cache對ehcache的封裝，基於annotation直接在方法上做了cache。結果報錯如上。

修改spring的EhCacheManagerFactoryBean配置即可，share修改爲true。這樣EhCacheManagerFactoryBean內部在得到shared信息就不會重複重複創建cache了。
：

<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
    	<property name="configLocation" value="classpath:ehcache.xml" />
    	<span style="color:#ff0000;"><property name="shared" value="true"/></span>
    </bean>
