                This class contains the employee detail.
            </meta>

            <id name = "id" type = "int" column = "id">
                <generator class="native"/>
            </id>

            <property name = "firstName" column = "first_name" type = "string"/>
            <property name = "lastName" column = "last_name" type = "string"/>
            <property name = "salary" column = "salary" type = "int"/>

        </class>
    </hibernate-mapping>

它与创建SessionFactory的Employee类和main类位于同一目录中。

它抛出此org.hibernate.MappingNotFoundException：资源：Employee.hbm.xml未找到异常。我怎样才能解决这个问题？谢谢
