本文详细解释了如何解决Hibernate框架中遇到的MappingException错误，特别是当出现'entityclassnotfound'错误时，需要修改类路径为绝对路径。通过示例代码，文章提供了具体的解决方案和步骤。

遇到这个错误：org.hibernate.MappingException: entity class not found: JPeople

一般系统自动生成的映射文件为： 


                        <hibernate-mapping> 
                                    <class name="User" table="...... 
                                        ....... 
                       </hibernate-mapping> 


                  要将class路径改为绝对路径。若User.java在包com.ssh.bean 


                 则要改为<class name="com.ssh.bean.User" ......>
