hibernate 4.2 异常 : Element type "hibernate-mapping" must be declared

Question

长期以来我一直在努力解决这个错误，请帮助我。

我收到错误:HHH000196:解析 XML 时出错(2):必须声明元素类型“hibernate-mapping”。

请帮我解决这个问题:

我的 pom.xml 看起来像这样:

<dependency>
            <groupId>javax.validation</groupId>
            <artifactId>validation-api</artifactId>
            <version>1.0.0.GA</version>
        </dependency>
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-entitymanager</artifactId>
            <version>4.2.1.Final</version>
        </dependency>
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>4.2.1.Final</version>
        </dependency>
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-validator</artifactId>
            <version>4.3.1.Final</version>
        </dependency>

我的 cfg.xml header :

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

我的 hbm.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-mapping>
    <class name="com.kivar.lumina.server.segment.Segment" table="segments">
        <id column="ID" name="id" type="java.lang.Long">
        </id>
    </class>
</hibernate-mapping>

Answer 1

DTD 的位置 URL 错误。在 hbm.xml 中，应该使用 hibernate-mapping-3.0.dtd 而不是 hibernate-configuration-3.0.dtd，如下所示:

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