Я потратил дни, пытаясь решить эту проблему, но безрезультатно. Я уже видел сообщение Unable to create requested service [org.hibernate.service.jta.platform.spi.JtaPlatform], которое имеет такое же название, но не помогло в решении этой проблемы. Кроме того, первоначальный плакат не ответил на запросы о дополнительной информации.Ошибка исключения: невозможно создать запрошенный сервис [org.hibernate.service.jta.platform.spi.JtaPlatform]
Я использую Eclipse (Kepler) на Windows 64bit, приложение Java EE Spring с Tomcat 7.0 и Hibernate. Я ранее получил Hibernate, работая правильно с SQLite db (временным db, который я смог прочитать и написать), но получал блокированные ошибки базы данных, когда на сайт приходило несколько запросов (и несколько попыток одновременного доступа к БД) , В результате я попытался включить JTA в свое приложение, чтобы справиться с этой ситуацией, но не смог запустить его. Я использую Maven, вот зависимостей Maven:

Я не используя hibernate.properties файл; У меня есть все настройки в файле hibernate.cfg.xml.
Раньше я пытался заставить свой собственный код работать, но теперь я перешел только для получения примера непосредственно из руководства пользователя hibernate 5.0 для работы, но я получаю ту же ошибку. Вот пример того, что я взял прямо из руководства пользователя на http://docs.jboss.org/hibernate/orm/5.0/userGuide/en-US/html_single/#d5e997 и модифицировал его немного:
public void doSomeWork()
{
StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySetting(AvailableSettings.TRANSACTION_COORDINATOR_STRATEGY, "jta");
// Note: depending on the JtaPlatform used and some optional settings,
// the underlying transactions here will be controlled through either
// the JTA TransactionManager or UserTransaction
Connection connection = null;
Session session = null;
try
{
Class.forName("org.sqlite.JDBC");
String sqliteDBPathAndNameStr = "C:\SB\Desktop\base\rclinicSqlite.db";
connection = DriverManager.getConnection("jdbc:sqlite:" + sqliteDBPathAndNameStr);
Statement statement = connection.createStatement();
statement.setQueryTimeout(30); // set timeout to 30 sec.
/*Configuration cf = new Configuration().configure("hibernate.cfg.xml");
cf.addAnnotatedClass(ClientTableObject.class);
cf.addAnnotatedClass(ProfessionalTableObject.class);
ServiceRegistry sr = ssrb.build();
sessionFactoryInst = cf.buildSessionFactory(sr);*/
SessionFactory sessionFactoryInst = new Configuration().configure().buildSessionFactory();
session = sessionFactoryInst.openSession();
//session = sessionFactoryInst.getCurrentSession();
// Since we are in CMT, a JTA transaction would
// already have been started. This call essentially
// no-ops
session.getTransaction().begin();
//doTheWork();
// Since we did not start the transaction (CMT),
// we also will not end it. This call essentially
// no-ops in terms of transaction handling.
session.getTransaction().commit();
}
catch (Exception e) {
// again, the rollback call here would no-op (aside from
// marking the underlying CMT transaction for rollback only).
e.printStackTrace();
// handle the underlying error
}
finally {
session.close();
}
}
Блок кода, который закомментирован является частью конфигурации, которую я использовал раньше, но пошел против что здесь основано на ссылке на эту ссылку для Hibernate 5 (Hibernate 5 :- org.hibernate.MappingException: Unknown entity).
Я получаю исключение и ошибку в названии выше, когда он выполняет сеанс Session session = sessionFactoryInst.openSession(). Вот консольный вывод до тех пор, пока не будет выбрано исключение и трассировка стека:

Любая помощь в этом вопросе была бы очень признательна. Я знаю, что некоторые параметры неверны, но мне непонятно, что не так, в том числе, как должны быть установлены настройки hibernate.connection.datasource, hibernate.jndi.class и hibernate.jndi.url , Благодарим вас за помощь и сообщите мне, нужна ли вам дополнительная информация для диагностики этой проблемы.
Я решил эту проблему и мне нужно было указать другое значение для hibernate.transaction.jta.platform в файле hibernate.cfg.xml. Ранее я думал, что руководство пользователя означает, что JtaPlatformResolver автоматически выбирает JtaPlatform для использования. Вместо этого я теперь использую atomikos, и теперь я указываю «com.atomikos.icatch.jta.hibernate4.AtomikosPlatform» для свойства hibernate.transaction.jta.platform. – user2797422
