Java 休眠配置文件

似乎我的配置文件有问题，但我真的不知道它可能是什么

我以前使用hibernate 3.6，现在使用hibernate 4.2，我忽略了一些重要的更改，但是文档似乎没有更改这部分

这是我的配置文件：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost/Test</property>
        <property name="connection.username">root</property>
        <property name="connection.password">*****</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">10</property>
        <property name="maxActive" value="10" />

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

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

      <!-- Mapping files -->
      <mapping resource="database/config/mapping/test.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

下面是返回语句：

mai 02, 2013 11:41:59 AM org.hibernate.annotations.common.Version <clinit>

我真的不明白怎么回事，也许有人能启发我。 很抱歉可能会造成干扰，如果我的帖子没有被改编，这是我的第一篇

致以最诚挚的问候。

在connection.url中指定端口

---

我读过一篇文章，其中说在Hibernate4中，我们需要在配置文件的属性名标记中提到Hibernate关键字

样本格式为-

休眠早期版本

休眠版本4

观察property name标记中的hibernate关键字

具体联系如下：

当您按照上述注释更改XML文件时，您必须更改DTD定义。

成功吗？我目前正在工作，今天晚些时候我会告诉您，我想可以，我会让您知道。我只是测试了它，它没有更改任何内容。@user2342594 Shucks，我很确定您需要指定端口，一定是别的东西。这可能是一个愚蠢的问题，但你的数据库是吗？是的，很明显，我在这里发布之前就试过了。我认为问题在于没有找到文件，我忽略了原因。cf:INFO:hh000206:hibernate.properties未找到我正在查找它好的，因此，确实是未加载的文件。现在我发现了一个新错误：mai 022013 10:58:05 PM org.hibernate.cfg.Configuration doConfigure INFO:hh000041:Configured SessionFactory:null。有什么想法吗？
