- hibernate引入的jar包：hibernate-release-5.0.12.Final.zip
- 数据库驱动：mysql-connector-java-5.1.46
二.安装hibernate插件
打开eclipse，点击help-->eclipse marketplace,如图输入:Hibernate Tools,再点击Goa按钮，找到JBoss Tools
点击install安装
如图选择Hibernate Tools，点击Confrm安装。安装完成后重启eclipse。
三. 创建工程
1.创建新项目hibernateDemo,在工程下建立lib文件夹。打开jar包的目录，导入lib/required下的和数据库的jar包，add to build path
在src下新建文件
点击next,默认文件名，点击next,如图配置数据库信息
选择UTF-8编码方式，点击finish,生成的hibernate.cfg.xml配置文件内容如下
<?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.password">a123</property> ???????<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/tb_test</property> ???????<property name="hibernate.connection.username">sherman</property> ???????<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> ???????????????????</session-factory></hibernate-configuration>
注意，把<session-factory name="MySQL">的name属性去掉，否则报org.hibernate.engine.jndi.JndiException异常，在该文件中添加一些配置，如图：
<?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.password">a123</property> ???????<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/tb_test</property> ???????<property name="hibernate.connection.username">sherman</property> ???????????????<!-- 配置数据库方言 --> ???????<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> ???????<!-- 控制台打印sql语句 --> ???????<property name="show_sql">true</property> ???????<!-- 格式化sql --> ???????<property name="format_sql">true</property> ???????<!--在启动时根据配置更新数据库 ?--> ???????<property name="hibernate.hbm2ddl.auto">update</property> ???????<!-- 配置连接池的连接数 --> ???????<property name="connection.pool_size">20</property> ???????????????<!-- 注册实体映射类 --> ???????<mapping class="com.gdut.app.entity.News"/> ???</session-factory></hibernate-configuration>
在src下新建一个包com.gdut.app.entity，存放持久化类News,News类代码如下
package com.gdut.app.entity;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.Table;@Entity@Table(name="NEWS_INFO")public class News {@Id@GeneratedValue(strategy=GenerationType.IDENTITY)private Integer id;private String title;private String content;public News() {}public News(Integer id, String title, String content) { ???this.id = id; ???this.title = title; ???this.content = content;}public Integer getId() { ???return id;}public void setId(Integer id) { ???this.id = id;}public String getTitle() { ???return title;}public void setTitle(String title) { ???this.title = title;}public String getContent() { ???return content;}public void setContent(String content) { ???this.content = content;}@Overridepublic String toString() { ???return "News [id=" + id + ", title=" + title + ", content=" + content + "]";}}编写测试类：
package com.gdut.app.entity;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.hibernate.cfg.Configuration;import org.junit.Test;public class BeanTest { ???@Test ???public void beanTest() {// ???????final StandardServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()// ???????????????.configure("hibernate.cfg.xml").build();// ???????// ???????SessionFactory sf = new MetadataSources(serviceRegistry).buildMetadata().buildSessionFactory(); ???????//两种方式都可以获取SessionFactory ???????Configuration cfg = new Configuration().configure(); ???????SessionFactory sf = cfg.buildSessionFactory(); ???????Session sess =sf.openSession(); ???????Transaction transaction = sess.beginTransaction(); ???????News n = new News(); ???????n.setContent("在广工毕业"); ???????n.setTitle("毕业季"); ???????sess.save(n); ???????transaction.commit(); ???????sess.close(); ???????????}}经过测试成功
或者通过映射文件
在com.gdut.app.entity包下简历一个News.hbm.xml映射配置文件，修改genarator的class属性为active
<?xml version="1.0"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><!-- Generated 2018-5-22 23:45:23 by Hibernate Tools 3.5.0.Final --><hibernate-mapping> ???<class name="com.gdut.app.entity.News" table="NEWS"> ???????<id name="id" type="java.lang.Integer"> ???????????<column name="ID" /> ???????????<generator class="native"/> ???????</id> ???????<property name="title" type="java.lang.String"> ???????????<column name="TITLE" /> ???????</property> ???????<property name="content" type="java.lang.String"> ???????????<column name="CONTENT" /> ???????</property> ???</class></hibernate-mapping>
在hibernate.cfg.xml中配置
<mapping resource="com/gdut/app/entity/News.hbm.xml"/>
测试验证成功。
整个工程架构如图：
