我正在学习使用java，因为我想在简单的java控制台应用程序中使用Hibernate。
我下载了Hibernate ORM的最新版本（4.3.8）
我在我的类路径中添加这个jar：
com.mysql.jdbc_5.1.5.jar网站
sqlite-jdbc-3.8.7.jar文件
休眠库\antlr-2.7.7.jar
Hibernate库\dom4j-1.6.1.jar
Hibernate Library\Hibernate-commons-annotations-4.0.5.Final.jar
Hibernate Library\Hibernate-core-4.3.8.Final.jar
Hibernate Library\Hibernate-jpa-2.1-api-1.0.0.Final.jar
Hibernate库\jandex-1.1.0.Final.jar
Hibernate库\javassist-3.18.1-GA.jar
Hibernate库\jboss-logging-3.1.3.GA.jar
Hibernate库\jboss-logging-annotations-1.2.0.Beta1.jar
Hibernate Library\jboss-transaction-api_1.2_spec-1.0.0.Final.jar
我的班级：
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "STUDENT_INFORMATIONS")
public class Student_Info {
@Id
private int rollNo;
private String name;
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;
}
}
我的主要代码：
Student_Info student = new Student_Info();
student.setName("Fabien");
student.setRollNo(1);
SessionFactory sessionFactory;
ServiceRegistry serviceRegistry;
Configuration configuration = new Configuration();
configuration.configure();
serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
configuration.getProperties()).build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(student);
session.getTransaction().commit();
session.close();
sessionFactory.close();
数据库
首先，我为SQLite创建hibernate.cfg.xml配置，并将dialect属性设置为“util.SQLiteDialect”
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="dialect">util.SQLiteDialect</property>
<property name="connection.driver_class">org.sqlite.JDBC</property>
<property name="connection.url">jdbc:sqlite:SQLiteJDBC.sqlite</property>
<property name="connection.username"></property>
<property name="connection.password"></property>
<!-- create / update -->
<property name="hibernate.hbm2ddl.auto">create</property>
<!-- Liste des classes à Mapper en base de données -->
<!-- <mapping resource="User.hbm.xml"/> -->
<mapping class="com.hibernate.Student_Info"/>
</session-factory>
</hibernate-configuration>
运行主程序时出现以下错误：

MySql数据库
在我尝试使用mysql数据库之后

<!DOCTYPE hibernate-configuration SYSTEM

1-你知道在SQLite上是否可以使用hibernate吗？
2-如果是，你知道为什么不起作用吗？
3-对于MySql，有什么问题？
非常感谢你！!
最佳答案
我想你刚才可能拼错了“冬眠”。。。
原因：com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:未知数据库“hierbnate”
尝试更改此：
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hierbnate</property>
对此：
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernate</property>
（除非你的数据库真的叫hierbnate，然后我就删除这个答案）。
