Question

我现在正在研究这几天。按照简单的youtube教程我试图设置我的休眠。以下是我创建的所有类，但是我已经检查了我的运行时配置，它们有驱动程序，构建路径也是如此。我不明白缺少什么，请尽快帮助！

的hibernate.cfg.xml

    <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/nebuladb</property>
    <property name="hibernate.connection.username">****</property>
    <property name="hibernate.connection.password">****</property>
    <property name="hibernate.connection.driver_class">org.postgresql.driver</property>
    <property name="hibernate.connection.pool_size">1</property>
    <property name="hibernate.connection.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
    <property name="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.hbm2ddl.auto">create</property>
    <mapping class="careers.nebula.ben.db.enitity.signup.UserEntity"/>
</session-factory>
