mysql - JAVA使用Hibernate的SchemaExport无法生成表

Question

代码如下

• hibernate.cfg.xml

<?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.username">root</property>
        <property name="hibernate.connection.password">123456</property>
        <property name="hibernate.connection.driver_class">org.mariadb.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mariadb://localhost:3306/test?useUnicode=true&amp;characterEncoding=UTF-8</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
        <property name="format_sql">true</property>
        <property name="hbm2ddl.auto">update</property>
        <property name="hibernate.current_session_context_class">thread</property>
        <mapping resource="entity/Students.hbm.xml"/>
        <mapping resource="entity/Users.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

• TestStudents.java

package entity;


import java.util.EnumSet;

//import org.hibernate.Session;
//import org.hibernate.SessionFactory;
import org.hibernate.boot.Metadata;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.tool.hbm2ddl.SchemaExport;
import org.hibernate.tool.schema.TargetType;
import org.junit.Test;

public class TestStudents {
    
    @Test
    public void testSchemaExport() {
        //创建配置对象
        Configuration config = new Configuration().configure();
        //创建服务注册对象
        ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(config.getProperties()).build();
        //创建sessionFactory
        //SessionFactory sessionFactory = config.buildSessionFactory(serviceRegistry);
        //创建session对象
        //Session session = sessionFactory.getCurrentSession();
        //创建SchemaExport对象
        Metadata metadata = new MetadataSources(serviceRegistry).buildMetadata();
        SchemaExport export = new SchemaExport();
        export.create(EnumSet.of(TargetType.DATABASE), metadata);
    }

}
