这是我运行junit测试时发生的情况...
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.
The source of the existing CacheManager is:
DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]
异常背后的原因是什么？是否可以同时运行1个以上的cacheManager？
这就是我使用Sping 3.1.1配置cachManager的方式。它将cacheManager的范围明确设置为“单例”
<ehcache:annotation-driven />
<bean
id="cacheManager"
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
scope="singleton"
/>
ehcache.xml看起来像
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
updateCheck="false"
maxBytesLocalHeap="100M"
name="cacheManager"
>
....
</ehcache>
最后我的课
@Component
public class BookingCache implements CacheWrapper<String, BookingUIBean> {
@Autowired
private CacheManager ehCacheManager;
....
}
我非常确定我在代码库中只处理一个cacheManager。其他一些可能正在运行第n个实例。
