数据库也有插入，测试程序如下：

public class EnentManger {

    public static void main(String[] args) {
        EnentManger mgr = new EnentManger();

        
            mgr.createAndStoreEvent("Myqq",new Date(),25);
       

        HibernateUtil.getSessionFactory().close();
    }

    private void createAndStoreEvent(String tit, Date theDate,int d) {
        Session session = HibernateUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
        Event heEvent=new Event();
        heEvent.setTitle(tit);
        heEvent.setDate(theDate);
        heEvent.setAge(d);
        session.save(heEvent);

        session.getTransaction().commit();
    }

}

但是问题出现了，数据库的插入条目显示如下：

无论 mgr.createAndStoreEvent("Myqq",new Date(),25);这句怎么设置数据，title和age值都不变，但是date变了，说明还是执行的啊，event表的类文件如下：

package main.java.org.hibernate.tutorial.domain;

import java.util.Date;

import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

import org.hibernate.annotations.GenericGenerator;
@Entity(name="events")//指定表名时必须在entity里设置，在@table里设置会产生异常

public class Event {
    private Long id;

    private String title;
    private Date date;
    private int age;

    public Event() {}
    
    @GenericGenerator(name = "generator", strategy = "native")
    @Id
   @GeneratedValue(generator = "generator")
    @Column(name="EVENT_ID",unique = true, nullable = false)
    public Long getId() {
        return id;
    }
    private void setId(Long id) {
        this.id = id;
    }
    @Column(name="EVENT_DATE")
    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }
   @Column(name="title")
    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }
    @Column(name="age")
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
}

希望有大神给出解释啊，是不是c3p0的原因啊
