篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了关于An association from the table XX refers to an unmapped class错误相关的知识,希望对你有一定的参考价值。

1.检查*.hbm.xml里面类全名

2.检查*.hbm.xml文件名是否正确(自己文件名由于copy 丢失hbm)

3.检查hibernate.cfg.xml文件中的相关联的两个<mapping resource=""/>的顺序,可能有其中一个需要引用另一个,但是另一个却还没有编译,就是说被用作外键的表要放在前面

4.检查hibernate.cfg.xml文件中是否添加了<mapping resource="xxxxx.hbm.xml"/>

 

我的错误:是因为未加载关联的实体 在application.xml文件中加入关联的模块jar包,顺序在关联的jar之前

<property name="mappingJarLocations">
        <list>
            <value>WEB-INF/lib/process-workflow-bundle-4.0.0-SNAPSHOT.jar</value>
            <value>WEB-INF/lib/operation-4.0.0-SNAPSHOT.jar</value>
        </list>
        </property>
