我想使用hibernate插入到我的postgresql数据库中，我完全或没有弄清楚为什么我一直收到这个错误，我想做的是让hibernate创建我的数据库表和列并插入到创建的表. 所以我的第一个错误是关于丢失的 jar 文件，这是我已经添加到我的 Hibernate 库中的 slf4j，但是在我再次运行应用程序后会弹出新错误，所以这是我的错误：
90 [main] INFO org.hibernate.annotations.common.Version - Hibernate Commons
Annotations 3.2.0.Final
100 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.6.10.Final
100 [main] INFO org.hibernate.cfg.Environment - hibernate.properties not found

这是我的 Jar 文件（在 Hibernate 库中）：
hibernate3.jar
antlr-2.7.6.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
javassist-3.12.0.GA.jar
jta-1.1.jar
slf4j-api-1.6.1.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
postgresql-9.1-902.jdbc4

用户详细信息类：

import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class UserDetail {
@Id
private int userId;
private String userName;
public int getUserId() {

我的主要课程：
package org.hibernate_main;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.user_detail.dto.UserDetail;
public class HibernateMain {
public static void main(String[] args){
UserDetail user = new UserDetail();
user.setUserId(1);
user.setUserName("Jerome");
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
}
}
伙计们，你能告诉我这个错误是什么以及如何修复它们，以及如何测试 XML 中的数据库连接是成功还是失败。多谢你们。
