我最近升级到Hibernate 5.1.0.Final（随附ehache）并使用Spring 3.2.11.RELEASE。尽管遵循了这里的建议 - Another unnamed CacheManager already exists in the same VM (ehCache 2.5)，我在运行JUnit测试时看到了错误。我在src / main / resources目录中有以下ehcache.xml文件
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd" updateCheck="false">
<!-- This is a default configuration for 256Mb of cached data using the JVM's heap, but it must be adjusted
according to specific requirement and heap sizes -->
<defaultCache maxElementsInMemory="10000"
eternal="false"
timeToIdleSeconds="86400"
timeToLiveSeconds="86400"
overflowToDisk="false"
memoryStoreEvictionPolicy="LRU">
</defaultCache>
<cache name="main" />
<!-- maxBytesLocalOffHeap="1g" -->
<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1,
multicastGroupPort=4446, timeToLive=32"/>
<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="hostName=localhost, port=40001,
socketTimeoutMillis=2000"/>
</ehcache>
我有一堆JUnit（v.4.11）测试，我通过Maven运行。它们都是这样结构的
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class MyServiceTest
{
但是当我运行任何测试时，例如，
mvn clean test -Dtest=MyServiceTest
我遭到伏击，有许多例外，如下所示......
Caused by: 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 ]

答案 0 :(得分：0)
尝试在echance.xml中的 ehcache 元素上指定CacheManager的名称
示例：
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd"
updateCheck="false" monitoring="autodetect"
dynamicConfig="true" name="mintakaOper_cache_manager">
...
</ehcache>
您可以看到名称被指定为“mintakaOper_cache_manager”。确保为不同的缓存管理器指定不同的名称
