我有这个结构的项目：

在此处输入图像描述

当我试图通过休眠访问 dtb 时，我得到了这个异常：

Initial SessionFactory creation failed.org.hibernate.MappingException: entity class not found: user/DBUser
V 02, 2013 9:17:10 ODP. org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [mvc-dispatcher] in context with path [/fit] threw exception [Handler processing failed; nested exception is java.lang.ExceptionInInitializerError] with root cause
java.lang.ClassNotFoundException: user/DBUser

你能告诉我，我的配置文件中的路径应该是什么样的？我尝试了几种组合，但我不知道如何编写它。

DBUser.hbm.xml：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="DontKnowWhatShallBeHere/DBUser" table="DBUSER">
        <id name="userId" type="int">
            <column name="USER_ID" precision="5" scale="0" />
            <generator class="assigned" />
        </id>
        <property name="username" type="string">
            <column name="USERNAME" length="20" not-null="true" />
        </property>
        <property name="createdBy" type="string">
            <column name="CREATED_BY" length="20" not-null="true" />
        </property>
        <property name="createdDate" type="date">
            <column name="CREATED_DATE" length="7" not-null="true" />
        </property>
    </class>
</hibernate-mapping>

hibernate.cfg.xml：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.password">password</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3049/test</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
        <mapping resource="DontKnowWhatShallBeHere/DBUser.hbm.xml"></mapping>
    </session-factory>
</hibernate-configuration>

一切看起来都很好。你能试试这个看看： <class name="user.DBUser" table="DBUSER">
