Java 最新的Hibernate和Derby:无法建立JDBC连接

我正在尝试创建一个使用Hibernate连接到Derby数据库的裸体项目。我正在使用Hibernate和Derby的最新版本，但是我得到了一个通用的

无法建立JDBC连接的
错误

这是我的芭比娃娃代码：

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class DatabaseTestMain {
    public static void main(String... args){
        Configuration derbyConfiguration = new Configuration().configure("hibernate-derby.cfg.xml");

        SessionFactory derbySF = derbyConfiguration.buildSessionFactory();
        Session derbySession = derbySF.openSession();

        derbySession.close();
    }
}

当我运行它时，我会得到以下堆栈跟踪：

但无论我做什么，我仍然得到上面的错误。我错过什么了吗

在从Hibernate 4.0.1升级到Hibernate 4.3.5时，我问过同样的问题。关于我的类路径来自哪里，升级到新版本等等，有一些问题。所以我试着用所有东西的最新版本重新开始一个全新的项目，但我仍然遇到了错误

编辑：我应该注意，所有这些设置在Hibernate 4.0.1中运行良好，Derby数据库不需要用户名或密码。
您正在使用
ClientDriver
连接到本地数据库。最近的derby文档（在撰写本文时）说

加载Derby的本地JDBC驱动程序的类是
org.apache.derby.jdbc.EmbeddedDriver
。加载Derby的
网络客户端驱动程序是类
org.apache.derby.jdbc.ClientDriver

请参阅

因此，为了让代码能够运行，如果您不想做太多更改，我建议您使用
EmbeddedDriver
。如果您仍然必须使用
ClientDriver
，则必须将连接URL更改为类似
jdbc:derby://localhost:1527/MyDbTest;create=true
，而且您必须为客户驱动程序提供用户名和密码
 是空白的。。。是否应该添加它？是否尝试将用户名设置为“sa”（无密码）并将“hbm2ddl.auto”设置为“create”？堆栈跟踪中必须有更多原因。@codeMan Derby数据库不需要用户名或密码。@Stefan堆栈跟踪中没有更多原因。这就是整个堆栈跟踪。我还应该注意到，这在Hibernate 4.0.1中运行良好。是否有任何特定的需要使用ClientDriver而不是EmbeddedDriver？切换到
EmbeddedDriver
似乎可以解决这个问题。不过，这在Hibernate 4.0.1中起到了作用——你知道他们是什么时候改变的吗？随着时间的推移，Hibernate内部经历了许多变化。它注册驱动程序和处理连接属性等的方式。例如，如果您尝试
System.out.println（DriverManager.getDriver（“jdbc:derby:”）.getClass（））在您的代码中，您将惊讶于实际的驱动程序是什么。。。
