我写的第一个hibernate程序,helloworld就出错了,不知道为啥,求大神指教~~~
首先附上我的hibernate.cfg.xml 配置:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost/hibernate</property>
<property name="connection.username">root</property>
<property name="connection.password">root</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<mapping resource="HibernateModel/student.hbm.xml"/>
</session-factory>
</hibernate-configuration>
以及我的student.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package=HibernateModel">
<class name="student" >
<id name="id" >
<generator class="native"/>
</id>
<property name="age"/>
<property name="name"/>
</class>
</hibernate-mapping>
以下是测试类:
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
import HibernateModel.student;
public class StudentTest {
private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;
public static void main(String[] args) {
student s = new student();
