The constructor SchemaExport(Configuration) is deprecated

Hibernate 中new SchemaExport(new AnnotationConfiguration().configure()).create(false, true);生成表未成功

• 最近在学习Hibernate的基础知识，但是由于所看教程中使用的Hibernate版本较低（3.x），而自己所用的版本为5.x，导致上述采用Annotation自动建表失败，警告：

  The constructor SchemaExport(Configuration) is deprecated

• 经查资料，这个写法在hibernate 5.x以后为deprecated，而且如果在hibernate 5.x中使用上述写法，将会报错。推荐写法：

// the .jar needed
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.boot.spi.MetadataImplementor;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry; //Note: here is not javax.imageio.spi.ServiceRegistry
import org.hibernate.tool.hbm2ddl.SchemaExport;

// SchemaExport
ServiceRegistry serviceRegistry = (ServiceRegistry) new StandardServiceRegistryBuilder().configure().build();  
MetadataImplementor metadataImplementor = (MetadataImplementor) new MetadataSources(serviceRegistry).buildMetadata();
SchemaExport export = new SchemaExport(serviceRegistry, metadataImplementor);
export.create(true, true);

Note：当采用SchemaExport运行成功，但却没生成表时，很可能是在实体类中未写@Entity！！
