hibernate出现错误

hibernate出现异常
执行hibernate测试类时出现异常，测试代码如下：

import com.pojo.Person;
import com.sessionFactory.HibernateSessionFactory;
import com.sun.jmx.trace.TraceDestination;
;
public class Test {

public static void main(String args[])
{
Session session = HibernateSessionFactory.getSession();
Transaction transaction = session.beginTransaction();

Person p = new Person();
p.setId("3");
p.setName("zhangsan ");
p.setAge("23");
session.save(p);

transaction.commit();
HibernateSessionFactory.closeSession();

}
}


异常信息：

log4j:WARN Please initialize the log4j system properly.

你的配置的 EntityMode 是 POJO, DOM4J 还是 MAP?

从 Hibernate 代码看，它说你的 EntityMode 无法猜测出来。

Java code

public String toLoggableString(Object value, SessionFactoryImplementor factory)
                        throws HibernateException {
                if ( value == null ) {
                        return "null";
                }
                Map result = new HashMap();
                EntityMode entityMode = tuplizerMapping.guessEntityMode( value );
                if ( entityMode == null ) {
                        throw new ClassCastException( value.getClass().getName() );
                }
                Object[] values = getPropertyValues( value, entityMode );
                for ( int i = 0; i < propertyTypes.length; i++ ) {
                        result.put( propertyNames[i], propertyTypes[i].toLoggableString( values[i], factory ) );
                }
                return StringHelper.unqualify( getName() ) + result.toString();
        }
