Hibernate将数据保存到数据库时的未知实体

Question

我正在使用oracle数据库和java应用程序在eclipse中使用Hibernate项目。

在我的Hibernate项目中添加新类（存在于我的数据库中）之后，运行我的java project.it成功加载也允许将数据从java项目添加到hibernate表但是将这些数据添加到数据库时出现此错误< / p>

DocumentWRONGMODDATESTATUS docstatus = new DocumentWRONGMODDATESTATUS();

这是我将数据添加到数据库的代码。

注意（我打开了会话，我测试了另一个类存在于同一个Hibernate项目中，与此类“Hibernate Project”具有相同的结构）

docstatus.setOriginalDocId(doc.getPdf().getId());

addDocumentWrongModDateStatus(docstatus ,Session );

此时每件事都很好，但是在线下面会给出错误（在调试模式下测试它）

<?xml version="1.0" encoding="UTF-8"?>

的hibernate.cfg.xml
