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 No appenders could be found for logger (org.hibernate.cfg.Environment).
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(); }
