java - hibernate 配置文件

Question

我的配置文件似乎有问题，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，有一些重要的更改我忽略了，但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>

这是我的 java 源代码:

public class CreateDB {
    public static void main(String argv[]){
        try {
            Configuration configuration = new Configuration();
            configuration.configure("database/config/DBCreate.cfg.xml");
            ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder().applySettings(configuration
                .getProperties());
            SessionFactory sessionFactory = configuration
                .buildSessionFactory(serviceRegistryBuilder.buildServiceRegistry());
        DBConnect.Disconnect(null, sessionFactory.openSession()); // Just logout from a session
        } catch (Exception e) {
            System.out.println("Database unreachable.");
        }
    }
}

这是返回语句:

mai 02, 2013 11:41:59 AM org.hibernate.annotations.common.Version <clinit>
INFO: HCANN000001: Hibernate Commons Annotations {4.0.1.Final}

mai 02, 2013 11:41:59 AM org.hibernate.cfg.Configuration getConfigurationInputStream
INFO: HHH000040: Configuration resource: database/config/DBCreate.cfg.xml
Database unreachable.

我真的不明白哪里出了问题，也许有人能够启发我。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。

致以诚挚的问候。

在connection.url中指定端口。

<property name="connection.url">jdbc:mysql://localhost:3306/Test</property>
