Hibernate5.x 使用SchemaExport生成数据表

在学习使用Hibernate生成数据表时，发现Hibernate4.x中的configuration已失效，新语法如下
`import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.boot.spi.MetadataImplementor;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.tool.hbm2ddl.SchemaExport;
import org.junit.Test;

public class TestStudents {

@Test
public void tsetSchemaExport(){
    ServiceRegistry serviceRegistry = new
StandardServiceRegistryBuilder().configure().build();
    MetadataImplementor metadata = (MetadataImplementor) new MetadataSources( serviceRegistry ).buildMetadata();  
    new SchemaExport(metadata).create(true, true);  
}

}`
