①普遍错误解决：*.hmb.xml文件中的属性名和pojo不一致（*.hbm.xml和*.Java没衔接好，不一致），字段属性没有正确配置，比如，*.hmb.xml中*.java的地址要明确（明确指出引用包的完整路径）；映射错误；有多个主键时，对生成的联合主键配置错误；拼写错误（包括多空格）等】

②Caused by: org.hibernate.HibernateException: Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]:

情况一：没有导入javassist.jar包；
情况二：查看映射文件，突然发现Could
not find a getter for picturepath in class com.tocean.cn.dao.entity.Admin所以明白了，属性没有对应，说明映射文件和模型类中的属性对应有错，于是解决。entity包中的属性命名与映射文件对应的命名大小写相同。建议以后使用copy防止出错。
