我最近升级到了Hibernate 5.1.0.Final（伴随的内部事件）并使用了Spring 3.2.11.RELEASE。尽管遵循这里的建议 - Another unnamed CacheManager already exists in the same VM (ehCache 2.5)，但在运行我的JUnit测试时发现错误。我有以下ehcache.xml中的文件在我的src/main/resources目录在我的Junit 4测试中运行Hibernate 5时出现“另一个未命名的CacheManager已经存在”错误
<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>
而且我有一大堆的JUnit（v.4.11）的测试中，我通过Maven的运行。他们都是结构化的，像这样
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class MyServiceTest
{
但是当我运行任何测试，例如，
mvn clean test -Dtest=MyServiceTest
我伏击与许多例外，看起来像下面...
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 ]

我用于配置Hibernate的上下文配置如下所示...

你找到了解决办法吗？当我们在弹簧测试之间更改上下文时，我们遇到了类似的问题。 – adam
是否有可能您正在使用多模块项目，或者您的一个JAR中是否还有您的或eh-cache配置文件的副本具有相同（或不包含）名称？ – adam
