- 1.去官网下载Jar包：以hibernate-release-5.2.16.Final为例
解压后将hibernate-release-5.2.16.Final\lib\required目录中的所有jar包导入
- 2.配置文件
将hibernate-release-5.2.16.Final\project\etc中hibernate.cfg.xml文件复制到src下
并且修改配置如下：
<!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.url">jdbc:mysql://localhost:3306/hibernate?serverTimezone=GMT</property><property name="hibernate.connection.username">root</property><property name="hibernate.connection.password">zhangpn</property><property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property><property name="hibernate.hbm2ddl.auto">update</property><mapping resource="com/zhangpn/pojo/User.hbm.xml"/></session-factory></hibernate-configuration>
- 3.为测试而创建一个pojo类
1 package com.zhangpn.pojo; 2 ?3 public class User { 4 ????private int id; 5 ????private String name; 6 ????private String password; 7 ?8 ????public int getId() { 9 ????????return id;10 ????}11 12 ????public void setId(int id) {13 ????????this.id = id;14 ????}15 16 ????public String getName() {17 ????????return name;18 ????}19 20 ????public void setName(String name) {21 ????????this.name = name;22 ????}23 24 ????public String getPassword() {25 ????????return password;26 ????}27 28 ????public void setPassword(String password) {29 ????????this.password = password;30 ????}31 32 }- 4.配置*.hbm.xml文件
<?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> ???<class name="com.zhangpn.pojo.User" table="user"> ???????<id name="id" column="id"> ???????????<generator class="native"/> ???????</id> ???????<property name="name"/> ???????<property name="password"/> ???</class></hibernate-mapping>
- 5.将User.hbm.xml加入hibernate.cfg.xml文件中
<!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.url">jdbc:mysql:///hibernate</property><property name="hibernate.connection.username">root</property><property name="hibernate.connection.password">zhangpn</property><property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property><mapping resource="com/zhangpn/pojo/User.hbm.xml"/></session-factory></hibernate-configuration>
- 6.测试
package com.zhangpn.test;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.hibernate.boot.Metadata;import org.hibernate.boot.MetadataSources;import org.hibernate.boot.model.naming.ImplicitNamingStrategyComponentPathImpl;import org.hibernate.boot.registry.StandardServiceRegistry;import org.hibernate.boot.registry.StandardServiceRegistryBuilder;import org.hibernate.cfg.Configuration;import org.hibernate.service.ServiceRegistry;import com.zhangpn.pojo.User;public class Test {public static void main(String[] args) {/** * hibernate 4 版本 *///Configuration cfg = new Configuration().configure();//ServiceRegistry registry = new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()).build();//SessionFactory sf = cfg.buildSessionFactory(registry);//Session session = sf.openSession();/** * hibernate 5 版本 */StandardServiceRegistry standardRegistry = new StandardServiceRegistryBuilder().configure().build();Metadata metadata = new MetadataSources(standardRegistry).getMetadataBuilder().applyImplicitNamingStrategy(ImplicitNamingStrategyComponentPathImpl.INSTANCE).build();SessionFactory sessionFactory = metadata.getSessionFactoryBuilder().build();Session session = sessionFactory.openSession();Transaction tx = session.beginTransaction();User user = new User();user.setName("zhangpn");user.setPassword("888888");session.save(user);tx.commit();session.close();}}- 测试结果
- 问题与解决：
如果遇到错误：Error executing DDL via JDBC Statement
建议：修改方言为：<property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
