java - 4.0 XSD 上的 Hibernate 异常

Question

第一次使用 Hibernate，遇到一个奇怪的错误。我使用的是 4.2.3 Final 版本，并且喜欢使用 4.0 XSD 架构，但如果这是让它工作所需要的，我将使用 3.0 DTD .

我的司机:

public static void main(String[] args) {
    Configuration configuration = new Configuration();
    configuration.configure("hibernate/cfg/hibernate.cfg.xml");
    ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder().applySettings(configuration
            .getProperties());
    SessionFactory sessionFactory = configuration
            .buildSessionFactory(serviceRegistryBuilder.buildServiceRegistry());
    Session session = sessionFactory.openSession();

    Transaction tx = session.beginTransaction();

    User user = new User("Dr.", "Sylvester", "McMonkey", "McBean", "IV");

    session.save(user);
    tx.commit();
    session.close();
}

我的hibernate.cfg.xml 文件，位于我的项目src/main/config/hibernate/cfg 下:

<?xml version="1.0" encoding="utf-8"?>
<hibernate-configuration
        xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
        xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration hibernate-configuration-4.0.xsd"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <session-factory>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.connection.driver">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://my-server:3306/my_db</property>
        <property name="hibernate.connection.username">myuser</property>
        <property name="hibernate.connection.password">password</property>

        <property name="show_sql">true</property>
        <property name="format_sql">true</property>
        <property name="use_sql_comments">true</property>

        <property name="hbm2ddl.auto">validate</property>

        <mapping resource="User.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

Eclipse 给我的堆栈跟踪:

validator 未找到架构。 xsi:schemaLocation 属性告诉它在与您正在验证的配置文档 (.../src/main/config/hibernate/cfg) 相同的目录中查找模式文档 hibernate-configuration-4.0.xsd。那是你拥有它的地方吗？
