Hibernate的配置跟简单创建一个表并插入一条数据

首先官网下载一个hibernate的架包，由于时间关系，博主已经分享到了百度网盘：https://pan.baidu.com/s/1Mw0Og3EKnouf84Njz9UicQ，提取码lens

Hibernate的插件：https://pan.baidu.com/s/1YLBe4m9wlfu5dXzYcrpS1Q ，提取码：lens

话不多说我们开始吧

刚开始可以创建一个普通的Java项目如上所是，导入架包，由于博主还不精通所以价包全部导入，架包的基本路径recv\hibernate-release-5.4.22.Final\hibernate-release-5.4.22.Final\lib\required。

接下来配置cfg文件，以.cfg.xml结尾。我们创建名为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="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
       
       <property name="hibernate.connection.url">jdbc:mysql:///user_db?characterEncoding=UTF-8</property>
       
       <property name="hibernate.connection.username">root</property>
       
       <property name="hibernate.connection.password">123456</property>

       
       
       <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
       
       <property name="hibernate.show_sql">true</property>
       <property name="hibernate.format_sql">true</property>
       
       <property name="hibernate.hbm2ddl.auto">update</property>

       
       <mapping resource="user-mapper.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

然后配置hbm文件,以hbm.xml结尾，我们创建名为：uesr-mapper.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
       "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
       "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
   
   <class name="com.zb.entity.UserInfo" table="user_info">
      
      
      <id name="userId" column="user_id">
          
          <generator class="native"></generator>
      </id>
      
      <property name="userName" column="user_name"/>
      <property name="userAge" column="user_age"/>
      <property name="userSex" column="user_sex"/>
      <property name="userAddress" column="user_address"/>
      <property name="phoneNumber" column="phone_number"/>
   </class>
</hibernate-mapping>

对了一定要创建一个实体类，hbm文件就是根据实体类创建的

接下来就是测试类了

package com.zb.test;

import java.util.Date;

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

import com.zb.entity.UserInfo;

public class TestMain {
   public static void main(String[] args) {
       //配置信息对象
       Configuration config = new Configuration();
       //加载全局配置文件
       config = config.configure("hibernate.cfg.xml");
       //创建Session工厂(Hibernate5以后)
       SessionFactory sessionFactory = config.buildSessionFactory();
       //创建数据库访问对象(建立与数据库的会话)
       Session session = sessionFactory.openSession();
       //获取事务对象(开启事务)
       Transaction t = session.beginTransaction();

       UserInfo ui = new UserInfo(null, "大公鸡", 69, "男", "高老庄", "6543211",new Date());
       session.save(ui);

       //UserInfo userInfo = session.get(UserInfo.class, 2);
       //System.out.println(userInfo);

       t.commit();
       session.close();
       sessionFactory.close();
   }
}
