今天抽个时间写个关于用Eclipse none和hibernate创建一个hibernate的小例子

一、新建一个Java项目

二、手动添加src和test文件夹，然后java build path ，手动添加hibernate和mysql的相关jar包，并引入junit4的相关支持

此处没有添加lib目录

三、此时的相关目录结构为

注意此处我引用的是hibernate5.1.0,

四、创建相应的目录，此处不做深处介绍，目录为下：

五、相应的代码：

Stu.java

public class Stu {
private int id;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Stu(int id, String name) {
super();
this.id = id;
this.name = name;
}
public Stu() {
super();
}
@Override
public String toString() {
return "Stu [id=" + id + ", name=" + name + "]";
}

}

hibernate.cfg.xml

<?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>
<property name="connection.username">root</property>

<property name="format_sql">true</property>
<property name="hbm2ddl.auto">create</property>

<mapping resource="Stu.hbm.xml"/>

</session-factory>
</hibernate-configuration>

Stu.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

<hibernate-mapping>

<property name="name" type="java.lang.String">
<column name="NAME" />
</property>
</class>
</hibernate-mapping>

stutest1.java

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

/*
*
* 在使用hibernate5版本时出现logging包重复的现象导致测试出现错误删除jboss-logging-3.1.0.GA即可正常运行
*
*
*
*/

public class stutest1 {

@Test
public void save(){
SessionFactory seFactory = null;
final StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure().build();
try{
seFactory = new MetadataSources( registry ).buildMetadata()
.buildSessionFactory();
} catch(Exception e){
StandardServiceRegistryBuilder.destroy( registry );
}


//2.创建一个Session对象

Session session = seFactory.openSession();

//3.开启事务
session.beginTransaction();
//4.执行操作

session.save(new Stu(1,"ssss"));

/*
//!!!!写hql语句，from 类名(区分大小写)
String hql = "from UserInfo";
@SuppressWarnings("unchecked")
List<UserInfo> list = session.createQuery(hql).list();
for(UserInfo u : list){
System.out.println(u);
}
*/
//5.提交事务
session.getTransaction().commit();
//6.关闭Session
session.close();
//7.关闭SessionFactory
seFactory.close();
}

}
