简单hibernate5.2.10入门配置

1、官网下载hibernate 5相关jar包

http://hibernate.org/orm/

2、解压后，在lib目录中找到required目录下的jar包添加至项目。再添加数据库驱动包，博主用MySQL

jar包添加后如下图：

3、创建数据库learndata、创建表userinfo，下面给出建表语句：

CREATE TABLE `NewTable` (
`id`  int NULL AUTO_INCREMENT ,
`username`  varchar(50) NULL ,
`password`  varchar(50) NULL ,
PRIMARY KEY (`id`)
);

4、编写实体类对象

package model;public class Userinfo {private int id;private String username;private String password;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}

5、编写映射文件

6、编写hibernate配置文件

com.mysql.jdbc.Driverjdbc:mysql://localhost:3306/learndatarootroot550 23 org.hibernate.dialect.MySQL5Dialectthreadtrueupdate

7、编写测试Java文件

package action;import model.Userinfo;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.hibernate.cfg.Configuration;public class Test {public static void main(String[] args) {//配置方法一//final StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure("hibernate.cfg.xml").build();//    SessionFactory sessionFactory = new MetadataSources(registry).buildMetadata().buildSessionFactory();//配置方法二Configuration cfg = new Configuration().configure("hibernate.cfg.xml");SessionFactory sessionFactory = cfg.buildSessionFactory();    Session session = sessionFactory.openSession();    Transaction transaction = session.beginTransaction();    Userinfo user = new Userinfo();    user.setUsername("root");    user.setPassword("123456");    session.save(user);    transaction.commit();}}

8、测试运行结果

9、异常总结

按照上面步骤，如果代码session.beginTransaction();报错，检查自己项目的jdk版本，hibernate5最好用jdk8，原因可以看http://blog.csdn.net/supegan1989/article/details/72862097
