我正在尝试一个简单的教程。 链接到教程
我已经按照那里写的所有步骤进行了操作,但仍然无法正常工作。这就是我得到的:
这是我的主要内容:
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package hibernatetest;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
/**
*
* @author ktelfon
*/
public class HibernateTest {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
Session session = null;
try {
SessionFactory sessionFactory = new org.hibernate.cfg.Configuration().configure("hibernatetest/hibernate.cfg.xml").buildSessionFactory();
session = sessionFactory.openSession();
session.beginTransaction();
System.out.println("Populating the database !");
Customer customer = new Customer();
customer.setCustomerName("Chathura");
customer.setCustomerAddress("221B,Moratuwa");
customer.setCustomerEmail("priyankarahac@gmail.com");
session.save(customer);
session.getTransaction().commit();
System.out.println("Done!");
} catch (Exception e) {
System.out.println(e.getMessage());
} finally {
session.flush();
session.close();
}
}
}
这是我的cfg:
<?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="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/retailer?zeroDateTimeBehavior=convertToNull</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>
<property name="show_sql">true</property>
<mapping resource="hibernatetest/customersmapping.hbm.xml"/>
<mapping/>
</session-factory>
</hibernate-configuration>
还有我的映射:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="hibernatetest.Customer" table="customers">
<id column="C_ID" name="customerID" type="int">
<generator class="native">
</generator></id>
<property name="customerName">
<column name="name">
</column></property>
<property name="customerAddress">
<column name="address">
</column></property>
<property name="customerEmail">
<column name="email">
</column></property>
</class>
</hibernate-mapping>
这里有什么问题?为什么它不会填充我的数据库?
