搭建Hibernate开发环境并运行Demo

1.下载对应的Hibernate版本hibernate-release-5.2.10.Final。创建Java项目，导入jar包。

2.创建实体类。

package text;

public class User {
private int id;
private String name;
private String age;
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 String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
}

3.配置实体类和数据库表的对应关系。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "hibernate-mapping-3.0.dtd" >
<hibernate-mapping>
<class name="text.User" table="user">
    <id name="id" column="ID"  type="int">
       <generator class="increment"/>
    </id>
    <property name="username" column="username" type="java.lang.String"  />
    <property name="age" column="age" type="int"/>
  </class>
</hibernate-mapping>

4.创建核心配置文件。

<session-factory>
<property name="hibernate.connection.driver_class">
com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">
jdbc:mysql://localhost:3306/test</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password"></property>
    <property name="hibernate.dialect">
         org.hibernate.dialect.MySQLDialect</property>
  <property name="show_sql">true</property>
  <mapping resource="text/user.hbm.xml"/>
</session-factory>

5.创建测试类。

package Usertest;

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

import text.User;

public class Test {
public static void main(String[] args) {
Configuration conf = new Configuration().configure();//1、读取配置文件
SessionFactory sf = conf.buildSessionFactory();// 2、创建SessionFactory
Session session = sf.openSession();// 3、打开Session
Transaction tx = null;
try{
tx = session.beginTransaction();// 4、开始一个事务
// 5、持久化操作
User user = new User();
user.setName("sang");
user.setAge(22);
session.save(user);
tx.commit();// 6、提交事务
}catch(Exception e){
if (null!=tx){tx.rollback();}
e.printStackTrace();
}finally{
session.close();// 7、关闭Session
}
}

}

6.测试结果。
