在PERSONDB类中，有五列分别命名为PERSON\u ID、PERSON\u FIRSTNAME、PERSON\u LASTNAME、PERSON\u GENDER、PERSON\u AGE

domain-classes.hbm.xml：

我改变了

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping
PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

到

现在，它起作用了。

我在下面的声明中遇到了一些问题

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

对于Hibernate5，我必须将其更改为以下内容才能工作

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

查看您的代码

  "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">   

将此更改为：

  "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

请您发布您的

com.hibernate.data.Person

类，并提供您个人中相应表格的描述b？是的。您的DOCTYPE DTD指向错误的版本。很高兴你明白了！
