Hibernate 4.1.5.SP1、Hibernate Validator 4.3.0.Final、およびJUnit4.8.1を使用しています。JUnitテストを実行すると、トランザクションをセットアップしようとすると、「java.sql.SQLException：jdbc：mysql：// localhost：3306/myprojectに適したドライバーが見つかりません」という例外が発生します。
@Before
public void setUpDAOTest() {
final Configuration configuration = new Configuration();
configuration.configure("junit_hibernate.cfg.xml")
.setProperty("javax.persistence.validation.mode", "none")
.setProperty("hibernate.show_sql", "false");
final ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
session = sessionFactory.openSession();
ThreadLocalSessionContext.bind(session);
tx = session.beginTransaction(); // exception thrown here
例外は私のURLが不正であることを示唆していますが、それは私には正しいようです。また、データベースが実行されていることを確認し、コマンドラインでデータベースに接続できることを確認しました。私のHibernate設定ファイルは
<?xml version='1.0' encoding='utf-8'?>

だから私は困惑しています。他に何が間違っている可能性がありますか？これが完全なスタックトレースです…</p>
