Question

我有一个与hibernate-core 4.2.3.Final一起使用的Maven项目。我已遵循此处提供的建议：

Hibernate Tutorial - Where to put Mapping File?

，src/main/resources中的配置文件如下所示：

<?xml version = "1.0" encoding = "utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="connection.url">jdbc:mysql://localhost:3306/justHibernate</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.username">root</property>
        <property name="connection.password">12345</property>
        <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
        <mapping resource="com/mycompany/app/model/Movie.hbm.xml" />
    </session-factory>
</hibernate-configuration>

映射文件位于com.mycompany.app.model类旁边的软件包Movie中：

<?xml version = "1.0" encoding = "utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="com.mycompany.app.model.Movie" table="Movies">
        <id name="id" column="id">
            <generator class="native"/>
        </id>
        <property name="title" column="title"/>
        <property name="director" column="director"/>
        <property name="synopsis" column="synopsis"/>
    </class>
</hibernate-mapping>

例外

配置找不到映射文件。

希望这会有所帮助。
