我的hibernate.cfg.xml文件： 錯誤在我的第一個休眠程序
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/hibernateTutorial</property>
<property name="connection.username">root</property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop the existing tables and create new one -->
<property name="hbm2ddl.auto">create</property>
<!-- Mention here all the model classes along with their package name -->
<mapping class="hibernate.Student_Info"/>
</session-factory>
</hibernate-configuration>
主類是：
package hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class Main {
public static void main(String[] args) {
Student_Info student = new Student_Info();
student.setName("jeevan");
student.setRollNo(1);
SessionFactory sessionFactory=new Configuration().configure().buildSessionFactory();
Session session=sessionFactory.openSession();
session.beginTransaction();
session.save(student);
session.getTransaction().commit();
session.close();
sessionFactory.close();
}
}
Model類是：
package hibernate;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="Student_Information")
public class Student_Info
{
@Id
private int rollNo;
public int getRollNo() {
return rollNo;
}
public void setRollNo(int rollNo) {
this.rollNo = rollNo;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
private String name;
}
我我得到以下錯誤：

我有lib文件夾中的所有jar文件，但它仍然無法正常工作，並在控制檯中顯示。
您可以發佈pom嗎？ –
發佈JPA，Hibernate API版本。可能與此相關http://stackoverflow.com/a/30554407/1897935 –
