Spring + Eclipselink + JtaTransactionManager = javax.persistence.TransactionRequiredException
Я действительно надеюсь, что вы можете мне помочь. Я искал ответы в Интернете, и ни один из них не работает.
Я использую Spring 3 + JTA + EclipseLink, но я получаю TransactionRequiredException при очистке транзакции. Теперь я очень привык просто определять свой постоянный контекст и вводить EntityManager, а транзакция обрабатывается сервером приложений.
Итак, вот что у меня есть.

Итак, как вы можете видеть, он правильно подключается к базе данных и "сохраняет" данные, но фактически никогда не выполняет оператор вставки. Затем при сбросе EM, это исключение.
Ваша помощь будет принята с благодарностью.
С уважением.

Хорошо, я понял, как это работает на 100%.
Прежде всего, мне не нужно определять постоянство (context/unit) в web.xml. Затем я удалил менеджер транзакций и компоненты entityManagerFactory. Также удален контекст: ведомая строка. Я также сделал мои "бобы" сессионные бобы без состояния. Затем я создаю его экземпляр с помощью весенних поисков в jndi. Это автоматически связывает EntityManager точно так, как я хочу. Больше не нужно беспокоиться о транзакциях, сервер приложений справится с этим.
так что мой последний конфиг:
spring-config.xml:
<jee:jndi-lookup jndi-name="java:global/Cartouchan-Web/CategoryController" id="categoryController"/>
<jee:jndi-lookup jndi-name="java:global/Cartouchan-Web/UserController" id="userController"/>
<bean id="applicationContextProvider" class="com.cartouchan.locator.beans.CustomApplicationContext"></bean>
<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
образец бобов:
import java.text.MessageFormat;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.apache.log4j.Logger;
@Stateless
public class CategoryController {
private static final Logger logger = Logger.getLogger(CategoryController.class);
@PersistenceContext
private EntityManager entityManager;
public CategoryController() {
// TODO Auto-generated constructor stub
}
public boolean createCategory(final String name) {
boolean result = false;
try {
com.cartouchan.locator.database.models.Category category = new com.cartouchan.locator.database.models.Category();
category.setName(name);
entityManager.persist(category);
entityManager.flush();
result = true;
} catch (Exception ex) {
logger.error(MessageFormat.format("Could not create the category {0}", name), ex);
}
return result;
}
public boolean updateCategory(final int id, final String name) {
boolean result = false;
try {
com.cartouchan.locator.database.models.Category category = getCategory(id);
category.setName(name);
entityManager.merge(category);
entityManager.flush();
result = true;
} catch (Exception ex) {
logger.error(MessageFormat.format("Could not update for the category {0} -{1}", id, name), ex);
}
return result;
}
public boolean deleteCategory(final int id) {
boolean result = false;
try {
com.cartouchan.locator.database.models.Category category = getCategory(id);
entityManager.remove(entityManager.merge(category));
entityManager.flush();
result = true;
} catch (Exception ex) {
logger.error(MessageFormat.format("Could not delete for the category {0}", id), ex);
}
return result;
}
public com.cartouchan.locator.database.models.Category getCategory(final int id) {
return (com.cartouchan.locator.database.models.Category) entityManager.createQuery("select p from Category p where p.id=:id").setParameter("id", id).getSingleResult();
}
public List<com.cartouchan.locator.database.models.Category> getAllCategories() {
return (List<com.cartouchan.locator.database.models.Category>) entityManager.createQuery("select p from Category p").getResultList();
}
}
Затем, чтобы использовать боб, просто выполните стандартный весенний поиск боба. Проще простого.
Свойство name="eclipselink.target-server" value="WebSphere_7"
установить тип сервера....
надеюсь, что это должно работать..
обратитесь к документации для более подробной информации http://docs.oracle.com/middleware/1212/toplink/TLADG/websphere.htm
Для использования транзакций JTA, управляемых сервером приложений, необходимо использовать EntityManagerFactroy созданный самим сервером приложений.
Т.е. вам нужно удалить свой LocalContainerEntityManagerFactoryBean декларация и получение EntityManagerFactory с сервера приложений через <jee:jndi-lookup>, Также вам необходимо настроить сервер приложений для создания EntityManagerFactory см. документацию вашего сервера приложений.
