初学hibernate，基本配置

首先是导包



其中最后一个asm包，可谓是让我费劲又伤神啊。具体情况就不说了。

其次是配置hibernate.cfg.xml文件

我用的是微软SQL Server

<?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>
<!-- Database connection settings -->
<property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="connection.url">jdbc:sqlserver://localhost:1433;databaseName=student</property>
<property name="connection.username">sa</property>
<property name="connection.password">1111</property>

<!-- JDBC connection pool (use the built-in) -->
<!--   <property name="connection.pool_size">1</property> -->
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<!-- Enable Hibernate's automatic session context management -->
<!-- <property name="current_session_context_class">thread</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 and re-create the database schema on startup -->
<property name="hbm2ddl.auto">update</property>
<!-- <mapping resource="yg/model/Stu.hbm.xml"/>  -->
<mapping class="yg.model.Stu" />
</session-factory>
</hibernate-configuration>

因为我使用的是Annotation的配置，使用注解。因此没有配置xxx.hbm.xml文件

package yg.model;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class Stu {

private int id;
private String name;
private int age;

public int getAge() {
return age;
}

@Id
public int getId() {
return id;
}
public String getName() {
return name;
}
public void setAge(int age) {
this.age = age;
}
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
}

接下来就是TEST测试类

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;

import yg.model.Stu;

public class StuTest {
public static void main(String[] args) {
Stu s = new Stu();
s.setId(1);
s.setName("s1");
s.setAge(1);

Configuration cfg = new AnnotationConfiguration();
SessionFactory sf = cfg.configure().buildSessionFactory();
Session session = sf.openSession();
session.beginTransaction();
session.save(s);
session.getTransaction().commit();
session.close();
sf.close();

}
}

ok,配置hibernate就完成了。
