Answer 1

如果您正在使用Spring配置Hibernate，那么在会话工厂中，您可以通过这种方式将位置固定到您的文件中，如果不是这种情况，请使用足够的信息更新您的问题

<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation">
<value>file:src/hibernate.cfg.xml</value>
</property>

Answer 2

如果您使用Spring with Hibernate，那么您可以执行类似的操作。

<beans>
    <bean id="YourClass"
        class="com.YourClass.
        <property name="sessionFactory">
            <ref bean="DbSessionFactory" />
        </property>     
    </bean>


    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName">
            <value>org.postgresql.Driver</value>
        </property>
        <property name="url">
            <value>jdbc:postgresql://localhost/yourdb</value>
        </property>
        <property name="username">
            <value>postgres</value>
        </property>
        <property name="password">
            <value>postgres</value>
        </property>     
    </bean>

    <bean id="DbSessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref local="dataSource"/>
        </property>     
        <property name="mappingResources">
            <list>
                <value>conf/hibernate/UserMapping.hbm.xml</value>               
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect"> org.hibernate.dialect.PostgreSQLDialect </prop>      
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.cache.use_second_level_cache"> true </prop>
                <prop key="hibernate.cache.use_query_cache">true</prop>
            </props>
        </property>
    </bean>
</beans>
