本文介绍了eclipse下搭建hibernate5.0环境的步骤，分享给大家，具体如下：
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;
}
@Override
public 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：
