关于hibernate的问题
小弟向往数据库里面存数据，用junit测试的时候，没有通过，也没有报错，查询数据库，里面也没有数据，希望大家帮我看看。
group类：
package model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="t_group")
public class Group {
private int id;
private String name;

@Id
@GeneratedValue
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

}

user类：

package model;

import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.ManyToOne;
import javax.persistence.Table;


@Entity
@Table(name="t_user")
public class User {
private Group group;
private int id;
private String name;


@ManyToOne(cascade=CascadeType.ALL)
public Group getGroup() {
return group;
}
@Id
@GeneratedValue
public int getId() {
return id;
}
public String getName() {
return name;
}
public void setGroup(Group group) {
this.group = group;
}
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
}

junit测试：

package model;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;


public class HusbandTest {

private static SessionFactory sessionFactory;

@BeforeClass
public static void beforeClass() {
new SchemaExport(new Configuration().configure()).create(false, true);
sessionFactory = new Configuration().configure().buildSessionFactory();
}
@AfterClass
public static void afterClass() {
sessionFactory.close();
}

@Test
public void testSaveUser() {
User u = new User();
u.setName("u1");
Group g = new Group();
g.setName("g1");
u.setGroup(g);
Session s = sessionFactory.getCurrentSession();
s.beginTransaction();
s.save(u);
s.getTransaction().commit();
}


public static void main(String[] args){
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
User u = new User();
u.setName("u1");
Group g = new Group();
g.setName("g1");
u.setGroup(g);
Session s = sessionFactory.getCurrentSession();
s.beginTransaction();
s.save(g);
s.save(u);
s.getTransaction().commit();
}
}

提示的信息：

------解决方案--------------------
不用setXX了吧，Hibernate保存的就是对象

对不起，刚开始学，还有点看不懂
