Hibernate-HelloWorld

首先，
1，创建Project，然后在library中加入hibernate所需的包。
hibernate.core
/required
slf-nop.jar
2,引入mysql的JDBC驱动包
3，在mysql中建立对应的数据库以及表
a)create database hibernate;
b)use hibernate;
c)create table student (id int primary key auto_increment, name varchar(20), age int);
4,建立Hibernate配置文件hibernate.cfg.xml
a)从参考文档的index.xml中参考
b)修改对应的数据库连接信息
c)注释掉不需要的内容

<?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>

        <!-- Database connection settings -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost/hibernate</property>
        <property name="connection.username">root</property>
        <property name="connection.password">111111</property>

        <!-- JDBC connection pool (use the built-in) -->
        <!-- <property name="connection.pool_size">1</property> -->

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.MySQLDialect</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="com/bjsxt/hibernate/model/Student.hbm.xml"/>

    </session-factory>

</hibernate-configuration
>

5，建立Student类

package com.bjsxt.hibernate.model;

public class Student {
    private int id;
    private int age;
    private String name;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

}

6，建立Student映射文件Student.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="com.bjsxt.hibernate.model">
    <class name="Student" table="student">
        <id name="id" column="id"></id>
        <property name="name"></property>
        <property name="age"></property>
    </class>
</hibernate-mapping
>

见参考文档api
7,将映射文件加入到hibernate.cfg.xml中，
8，建立StudentTest类，

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

import com.bjsxt.hibernate.model.Student;


public class StudentTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Student s=new Student();
        s.setId(1);
        s.setAge(1);
        s.setName("s1");

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

}

搭建完成。
执行后

Hibernate: insert into student (name, age, id) values (?, ?, ?)

在mysql中查询，已经插入数据。
