私は冬眠するのが初めてで、それを使用する最初のプログラムを作成しようとしています。
プロジェクトのビルドにmavenを使用しています。これらの依存関係を宣言しました:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.1.5.SP1</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.1.5.SP1</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-tools</artifactId>
<version>3.2.4.GA</version>
</dependency>
次に、休止状態の構成ファイルを作成しました。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory name="">
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">******</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost/vcsdb</property>
<property name="hibernate.connection.username">vcsuser</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<mapping class="org.test.database.Project"/>
</session-factory
</hibernate-configuration>
次に、リバース エンジニアリング ファイルを作成しました。
<?xml version="1.0" encoding="UTF-8"?>
Eclipse 休止状態プラグインを使用して、データベースに存在する唯一のテーブルを表すエンティティを作成しました。

最後に、アプリケーションのメイン サーブレット クラスに次のコード行を追加しました。
Configuration sessionFactory = (Configuration) new Configuration()
.configure() // configures settings from hibernate.cfg.xml
.buildSessionFactory();
しかし、アプリケーションを起動しようとすると、次のエラー メッセージが表示されます。
