hibernate5 junit测试

Hibernate5的junit测试
maven包：pom.xml

<dependencies>
        <dependency>
            <groupId>org.hibernate</groupId>

1、测试项目结构

2、hibernate.cfg.xml配置文件

<?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="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/hibernate?useUnicode=true&amp;characterEncoding=UTF-8&amp;useSSL=false</property>
        <property name="connection.username">root</property>
        <property name="connection.password"></property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>
        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>
        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">update</property>
        <!-- Names the annotated entity class -->
        <mapping class="com.jxm.hibernate.model.Event"/>
    </session-factory>
</hibernate-configuration>

3、Event.java实体类

package com.jxm.hibernate.model;

import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

import org.hibernate.annotations.GenericGenerator;

@Entity
@Table( name = "EVENTS" )
public class Event {
    private Long id;

    private String title;
    private Date date;

    public Event() {
        // this form used by Hibernate
    }

    public Event(String title, Date date) {
        // for application use, to create new events
        this.title = title;
        this.date = date;
    }

    @Id
    @GeneratedValue(generator="increment")
    @GenericGenerator(name="increment", strategy = "increment")
    public Long getId() {
        return id;
    }

    private void setId(Long id) {
        this.id = id;
    }

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name = "EVENT_DATE")
    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }
}

3、测试类 TestHibernate.java

package com.jxm.hibernate.test;

import java.util.Date;
import java.util.List;

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

import com.jxm.hibernate.model.Event;

import junit.framework.TestCase;

public class TestHibernate extends TestCase {
    private SessionFactory sessionFactory;

    @Override
    protected void setUp() throws Exception {
        // A SessionFactory is set up once for an application!
        // configures settings from hibernate.cfg.xml
        final StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure() 
                .build();
        try {
            sessionFactory = new MetadataSources(registry).buildMetadata().buildSessionFactory();
        } catch (Exception e) {
            // The registry would be destroyed by the SessionFactory, but we had
            // trouble building the SessionFactory
            // so destroy it manually.
            StandardServiceRegistryBuilder.destroy(registry);
        }
    }

    @Override
    protected void tearDown() throws Exception {
        if (sessionFactory != null) {
            sessionFactory.close();
        }
    }

    // @Test
    @SuppressWarnings("unchecked")
    public void testAdd() {
        // create a couple of events...
        Session session = sessionFactory.openSession();
        session.beginTransaction();
        session.save(new Event("再来一次测试", new Date()));
        session.save(new Event("用中文来测试", new Date()));
        session.getTransaction().commit();
        session.close();

        // now lets pull events from the database and list them
        session = sessionFactory.openSession();
        session.beginTransaction();
        List<Event> result = session.createQuery("from Event").list();
        for (Event event : (List<Event>) result) {
            System.out.println("Event (" + event.getDate() + ") : " + event.getTitle());
        }
        session.getTransaction().commit();
        session.close();
    }
}

注意hibernate5用的方言：org.hibernate.dialect.MySQL5Dialect
