spring - 将 JTA、Hibernate 4 和 Spring 4 与 WebLogic 集成

Question

我在实现 JTA/Hibernate/Spring 应用程序(使用 WebLogic 10.3 作为服务器)时遇到了严重问题。我最初使用的是 Spring 编程配置，但已将其移至 Spring XML 配置以过滤掉潜在问题。当我使用 HibernateTransactionManager 而不是 JtaTransactionManager 时，它工作得很好，但现在找不到线程的 Session。

当我查看 sessionFactory 时，它不为空，但 getSession() 不返回 session 。

你能帮我解决这个问题吗？谢谢!

我的 Dao 实现:

import java.util.Collection;
import java.util.LinkedHashSet;
import java.util.List;

...

import org.hibernate.Criteria;
import org.hibernate.Hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Restrictions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import mil.navy.navsupbsc.utilities.HibernateConfiguration;

@Repository
public class ContactDAOImpl implements ContactDAO {

    @Autowired
    SessionFactory sessionFactory;

    public Session getSession() {
        try {
            sessionFactory.openSession();
            return sessionFactory.getCurrentSession();
        } catch (NullPointerException e) {
            e.printStackTrace();
            throw e;
        }

    }

@SuppressWarnings("unchecked")
public List<Contact> listContact() {

    List<Contact> contactList = getSession().createCriteria(Contact.class)
            .list();
...

我的 Spring-Servlet.xml 文件是:

Answer 1

根据@M 的回答。 Deinum(如果您将您的评论放在答案中，我会将其标记为正确)，我已经解决了问题。

解决方案是将数据源(引用我之前指定的 JNDI 数据源)添加为 <property name="dataSource" ref="NCS"/> .我还将 jtaTransactionManager 引用为 <prop key="hibernate.transaction.jta.platform">org.hibernate.service.jta.platform.internal.WeblogicJtaPlatform</prop>

NOTE: for other servers other than WebLogic, replace .WebLogicJtaPlatform with your specific server's JtaPlatform name. Specific implementations can be found at http://docs.jboss.org/hibernate/orm/4.1/javadocs/org/hibernate/service/jta/platform/internal/AbstractJtaPlatform.html

最后，我改变了sessionFactory.openSession()至 sessionFactory.getSession在我的 DaoImplementation 文件中。

我希望这对其他人也有帮助!
