Rhythmk 一步一步学 JAVA（5） Hibernate环境配置

配置信息：

  JDK 1.6

  Hibernate 3.3

  mysql  5.6

项目结构如下：

hibernate.cfg.xml文件：

<?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">

<!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration>

    <session-factory>
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/eftest</property>
        <property name="connection.username">root</property>
        <property name="connection.password">wangkun</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="myeclipse.connection.profile">com.mysql.jdbc.Driver</property>
        <!--是否在后台显示Hibernate用到的SQL语句，开发时设置为true，便于差错，程序运行时可以在Eclipse的控制台显示Hibernate的执行Sql语句。项目部署后可以设置为false，提高运行效率 -->
        <property name="hibernate.show_sql">true </property>
        <mapping resource="com/rhythmk/model/NewsImage.hbm.xml" />
    </session-factory>

</hibernate-configuration>

NewsImage:

package com.rhythmk.model;


/**
 * NewsImage entity. @author MyEclipse Persistence Tools
 */

public class NewsImage implements java.io.Serializable {

    // Fields

    private Long id;
    private Integer newsId;
    private Short isDefault;
    private String imgSrc;
    private String imgSrcOrg;
    private Short ord;

    // Constructors

    /** default constructor */
    public NewsImage() {
    }

    /** full constructor */
    public NewsImage(Integer newsId, Short isDefault, String imgSrc,
            String imgSrcOrg, Short ord) {
        this.newsId = newsId;
        this.isDefault = isDefault;
        this.imgSrc = imgSrc;
        this.imgSrcOrg = imgSrcOrg;
        this.ord = ord;
    }

    // Property accessors

    public Long getId() {
        return this.id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public Integer getNewsId() {
        return this.newsId;
    }

    public void setNewsId(Integer newsId) {
        this.newsId = newsId;
    }

    public Short getIsDefault() {
        return this.isDefault;
    }

    public void setIsDefault(Short isDefault) {
        this.isDefault = isDefault;
    }

    public String getImgSrc() {
        return this.imgSrc;
    }

    public void setImgSrc(String imgSrc) {
        this.imgSrc = imgSrc;
    }

    public String getImgSrcOrg() {
        return this.imgSrcOrg;
    }

    public void setImgSrcOrg(String imgSrcOrg) {
        this.imgSrcOrg = imgSrcOrg;
    }

    public Short getOrd() {
        return this.ord;
    }

    public void setOrd(Short ord) {
        this.ord = ord;
    }

}

NewsImage.hbm.xml

</hibernate-mapping>

测试类：

package com.rhythmk.test;

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

import com.rhythmk.model.NewsImage;

public class testuser {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        SessionFactory sessionfac = new Configuration().configure()
                .buildSessionFactory();
        Session session = sessionfac.openSession();
        NewsImage entity = new NewsImage();
        org.hibernate.Transaction tx = session.beginTransaction();
        entity.setImgSrc("imgsrc_______");

        entity.setImgSrcOrg("imgsrc_ord");

        entity.setIsDefault(((short) 1));
        entity.setNewsId(100);

        entity.setOrd(((short) 1));

        session.save(entity);
        tx.commit();

        System.out.print("输出成功。");

    }

}

 

 执行输出结果：

Hibernate: insert into eftest.news_image (NewsID, IsDefault, ImgSrc, ImgSrcOrg, Ord) values (?, ?, ?, ?, ?)

输出成功。
