找到问题了。myeclipse的包没有引入。不知道怎么回事，有时候打开myeclipse的时候，项目中就会丢失一些包！重新导一下就好了。
我用的是myeclipse 8.5

org.hibernate.MappingException

我怀疑是你spring配置文件里配置这个类 匹配错了

ApplicationContext cxt = new ClassPathXmlApplicationContext("com/sj/applicationContext.xml");
customerDao = (CustomerDao) cxt.getBean("customerDao");
楼主是用注解还是配置文件？
用配置文件的话 看看在com/sj/applicationContext.xml中是否存在customerDao bean及
<property name="mappingResources">
<list>
<value>你要配置的实体 在你的项目应该是Customer的实体的绝对路径</value>
</list>
</property>

还想问一下，是不是myeclipse8.5引入的包经常会出现引入错误，或者丢失的问题？

CustomerDaoTest 把这个文件贴出来吧 不然不懂 java.lang.ClassNotFoundException: org.hibernate.MappingException
