hbm2java 3 - 找不到映射类

Question

我使用下面的插件生成我的实体类。 当我执行命令 mvn hibernate3:hbm2java 我确实收到了这个错误：

创建 AntRun 任务时出错。：发生 Ant BuildException：java.lang.NoClassDefFoundError: org/hibernate/engine/Mapping: org.hibernate.engine.Mapping

我确实尝试了每个休眠版本，但我找不到包含指定类的版本。

Answer 1

Mapping接口在Hibernate 4及之后的版本中被移除。相反，您可以使用 MetadataImplementor 接口来访问实体的元数据。

因为您使用的是 Hibernate 4.3.11。最后，您可以尝试更改 hibernate3-maven-plugin 配置以使用 MetadataSources 工具而不是 HibernateTool。您可以通过将当前配置替换为：

<metadataSources destdir="${project.build.sourceDirectory}">
    <classpath>
        <path location="${project.build.sourceDirectory}/classes"/>
    </classpath>
    <configuration>
        <jdbc-connection>
            <!-- your database connection details here -->
        </jdbc-connection>
        <hibernate-mapping package="com.cm.sourcegenerator">
            <fileset dir="${basedir}/src/main/resources/hibernate">
                <include name="**/*.hbm.xml"/>
            </fileset>
        </hibernate-mapping>
    </configuration>
</metadataSources>
