大概有以下几种原因： 1. 实体类的属性对象没有设置setter或者getter。 http://stackoverflow.com/questions/18042247/could-not-get-constructor-for-org-hibernate-persister-entity-singletableentitype 2. 没有导入javassist的jar文件 (javassist-3.15.0-GA.jar什么的） http://blog.csdn.net/xiaochangwei789/article/details/7712725 3. 我类文件和映射文件属性不对应。 我的实体类中的属性对象名和映射文件的property name不一致。
