Question

我尝试使用Hibernate OGM为mongoDB配置我的Spring Web应用程序，使用java 1.6和OGM 4.1.3.Final。

对于Session我编写HibernateUtil.java，它可以正常使用JUnit测试，但它会抛出异常。

Hibernate.java

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.ogm.cfg.OgmConfiguration;

public class HibernateUtil {

    private static final Logger log = Logger.getLogger(HibernateUtil.class.getName());
    private static final SessionFactory sessionFactory;
    private static final StandardServiceRegistry serviceRegistry;

    static {
        try {
            // create a new instance of OmgConfiguration
            OgmConfiguration cfgogm = new OgmConfiguration();
            // process configuration and mapping files
            cfgogm.configure("hibernate_mongoDB.cfg.xml");
            // create the SessionFactory
            //cfgogm.getProperties();
            serviceRegistry = (StandardServiceRegistry) new StandardServiceRegistryBuilder()
                .applySettings(cfgogm.getProperties()).build();
            sessionFactory = cfgogm.buildSessionFactory(serviceRegistry);
        } catch (Exception ex) {
            log.log(Level.SEVERE, "Initial SessionFactory creation failed !",
                ex);
            throw new EdumissException(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

}

            player.setId("2");
            player.setAge((short) 24);
            player.setBirth(new Date());
            player.setName("Pankaj");
            player.setSurname("Saboo");


            session.beginTransaction();
            session.save(player);
            session.getTransaction().commit();

            String hql = "FROM Players";
            Query query = session.createQuery(hql);
            List results = query.list();
            //List results = cr.list();
            for (Object object: results) {
                System.out.println("Data : " + object);
            }


            //session.flush(); // flush happens automatically anyway

        } catch (RuntimeException re) {
            session.getTransaction().rollback();
            throw re;

在Tomcat上部署之后，我正在通过另一个jsp，HibernateUtil.java在下面的行中抛出异常

OgmConfiguration cfgogm = new OgmConfiguration();

异常行是

java.lang.IncompatibleClassChangeError：class org.parboiled.transform.ClassNodeInitializer将org.objectweb.asm.ClassVisitor接口作为超类

请帮我解决这个问题。提前谢谢

Answer 1

更新你的ASM jar，你可以从这里下载，

http://grepcode.com/snapshot/repo1.maven.org/maven2/org.ow2.asm/asm-all/4.0

还要检查parboiled-core和parboiled-java jar的可扩展版本。

在lib中包含所有必需的jar后，针对新库重新编译代码并尝试运行。

Answer 2

问题已解决。

实际上我的应用程序连接到mysql和mongodb。所以我一起使用hibernate和hibernate OGM。以前对于mysql我在web应用程序的.hbm.xml中写了一些命名查询。因此，在从HibernateUtil.java创建会话时使用hibernate-OGM切换到mongoDB时，hibernate扫描.hbm.xml文件，该文件包含未被Hibernate OGM解析的命名查询，因为这些查询具有sql语法。所以它引发了一个例外。在评论sql查询后，它可以正常工作。

@Zia：Thanx。
