解决eclipse下运行junit测试抛出NoSuchMethodError异常的问题

异常如下：

Caused by: java.lang.NoSuchMethodError: net.sf.ehcache.Cache.(Ljava/lang/String;ILnet/sf/ehcache/store/MemoryStoreEvictionPolicy;ZLjava/lang/String;ZJJZJLnet/sf/ehcache/event/RegisteredEventListeners;Lnet/sf/ehcache/bootstrap/BootstrapCacheLoader;II)V
	at org.springframework.cache.ehcache.EhCacheFactoryBean.createCache(EhCacheFactoryBean.java:354)
	at org.springframework.cache.ehcache.EhCacheFactoryBean.afterPropertiesSet(EhCacheFactoryBean.java:331)
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1514)
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1452)

原因可能是ehcache的包版本不对，但是pom.xml中确实是正确的版本，应该是eclipse运行junit时用的是另一个版本的包。

可以这样解决：
Run -> Debug Configurations... -> 选中你的junit任务 -> Classpath -> Bootstrap Entries中增加正确的jar包。如图
