Eclipse Maven MySQL Hibernate


1.创建Maven项目,选择Archetype为archetype-maven-quickstart

2.添加mysql依赖

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.0.2</version>
</dependency>

注意:版本对应

3.添加Hibernate依赖

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.4.1.Final</version>
</dependency>

4.添加Eclipse Hibernate插件

打开Help->Install new software,输入:http://download.jboss.org/jbosstools/updates/stable/kepler/选择:Jboos Web and Java EE Development下面的Hibernate Tools

5.创建Hibernate配置文件

<?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">
<hibernate-configuration>
 <session-factory>
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  <property name="hibernate.connection.password">123456</property>
  <property name="hibernate.connection.url">jdbc:mysql://localhost:3308/codingdict</property>
  <property name="hibernate.connection.username">root</property>
  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
  <mapping resource="com/codingdict/test_hibernate/Person.hbm.xml"/>
 </session-factory>
</hibernate-configuration>

6.创建实体类

package com.codingdict.test_hibernate;

public class Person {
    public Person() {
        super();
        // TODO Auto-generated constructor stub
    }
    public Person(int id, String name) {
        super();
        this.id = id;
        this.name = name;
    }
    private int id;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    private String name;
}

7.创建映射文件

<?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 2019-3-13 13:27:21 by Hibernate Tools 3.4.0.CR1 -->
<hibernate-mapping>
    <class name="com.codingdict.test_hibernate.Person" table="PERSON">
        <id name="id" type="int">
            <column name="ID" />
            <generator class="assigned" />
        </id>
        <property name="name" type="java.lang.String">
            <column name="NAME" />
        </property>
    </class>
</hibernate-mapping>

8.创建表

create table Person(id int auto_increment,name varchar(20));

9.测试

package com.codingdict.test_hibernate;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;

public class App {
    private static SessionFactory sessionFactory=null;
    public static void main(String[] args) {
        // A SessionFactory is set up once for an application!
        final StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure()
                .build();
        try {
            sessionFactory = new MetadataSources(registry).buildMetadata().buildSessionFactory();
            sessionFactory.openSession();
            Session session = sessionFactory.openSession();
            Transaction tx = session.beginTransaction();
            session.save(new Person(1,"tom"));
            tx.commit();
        } catch (Exception e) {
            System.out.println(e);
        }
    }
}
