class path resource [applicationContext.xml] cannot be opene

在做Hibernate+Spring的DAO测试时，（用到Junit） ，测试时找不到Spring的配置文件，applicationContext.xml。具体异常如下：
org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [applicationContext.xml]; nested exception is java.io.FileNotFoundException: class path resource [applicationContext.xml] cannot be opened because it does not exist
java.io.FileNotFoundException: class path resource [applicationContext.xml] cannot be opened because it does not exist

问了师兄才搞定，原来是没有设置test类的classpath.具体做法是选择Debug=>>Debug...,在对话框右侧有Junit选项，选择测试的类，右边有设置classpath 的选项，设置好就行了。
