我正在学习Hibernates并且在练习时遇到了这个奇怪的问题,有时,当我进行更改并运行程序时,我的eclipse控制台突然停止显示最后一行Hibernate: drop table UserDetails
。要使程序运行,我需要重新启动Eclipse程序。
以下是我的代码。
UserDetails.java
package org.hibernates.dto;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Lob;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
@Entity
public class UserDetails {
@Id
@Column(name = "User_ID")
private int userId;
@Column(name = "User_Name")
private String userName;
@Temporal(TemporalType.TIME)
private Date date;
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getDesription() {
return desription;
}
public void setDesription(String desription) {
this.desription = desription;
}
@Lob
private String address;
private String desription;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}
HibernatesTest.java
package org.hibernates.dto;
import java.util.Date;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
public class HibernatesTest {
public static void main(String[] args) {
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("User 1");
user.setDate(new Date());
user.setAddress("User Address");
user.setDesription("User Desription");
Configuration configuration = new Configuration().configure();
StandardServiceRegistryBuilder builder = (StandardServiceRegistryBuilder) new StandardServiceRegistryBuilder()
.applySettings(configuration.getProperties());
ServiceRegistry serviceRegistry = builder.build();
SessionFactory factory = configuration.buildSessionFactory(serviceRegistry);
Session session = factory.openSession();
Transaction tx = session.beginTransaction();
session.save(user);
tx.commit();
session.close();
}
}
hibernate.cfg.xml中
<!DOCTYPE hibernate-configuration PUBLIC

</session-factory>

请让我知道我哪里出错了,我该如何解决这个问题。

您需要关闭会话工厂
factory.close()
