这是我的 hibernate.cfg.xml

<session-factory>

    <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
    <property name="hibernate.connection.password">root</property>
    <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/LoginForm</property>
    <property name="hibernate.connection.username">postgres</property>
    <property name="hibernate.default_schema">public</property>
    <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
    <property name="javax.persistence.validation.mode">none</property>
    <property name="show_sql">true</property>
    <property name="hibernate.format_sql" value="true"/>
    <property name="hbm2ddl.auto">create</property>

    <mapping class="com.isti.client.model.User" />

</session-factory>

Answer 1

没有

<property name="show_sql">true</property>
<property name="hibernate.format_sql" value="true"/>

看起来不一致？特别是缺少 value 属性看起来不正确。
