我的休眠有问题

痕迹：

实际上我不明白为什么它不起作用，因为前一段时间它运行良好并且在我离开项目一段时间后，此时我可以在 eclips 或其他任何东西上安装一些插件，当然我明白代码不能神奇地改变。那么，您认为这种行为的原因是什么？

抱歉……我怎么忘记了……这里是 Hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?>

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.5//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <!-- Database connection settings -->
        <property name="connection.driver_class">org.postgresql.Driver</property>
        <property name="connection.url">jdbc:postgresql://localhost:5432/mydb</property>
        <property name="connection.username">postgres</property>
        <property name="connection.password">1</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">2</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">update</property>

        <!-- Names the annotated entity class -->
        <mapping class="documentElements.Header"/>
        <mapping class="documentElements.Detail"/>


    </session-factory>

</hibernate-configuration>

在我改变之后

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.5//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

至：

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

一切都开始工作了。我不明白为什么它第一次不起作用。马贝我需要重新启动项目...
