通过hibernate的SchemaExport工具导出sql脚本

配置好hibernate的配置文件和映射文件以后可以通过SchemaExport工具导出sql脚本。

import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;

public class ExportDB {

	public static void main(String[] args) {
		Configuration cf=new Configuration().configure();
		SchemaExport sexport=new SchemaExport(cf);
		sexport.create(true, true);
		System.out.println("导出成功");
	}

}

运行结果：

  alter table Student 
        drop 
        foreign key FKF3371A1B51FD6C4E

    drop table if exists Class

    drop table if exists Student

    create table Class (
        id integer not null auto_increment,
        name varchar(255),
        primary key (id)
    )

    create table Student (
        id integer not null auto_increment,
        name varchar(255),
        class_id integer,
        primary key (id)
    )

    alter table Student 
        add index FKF3371A1B51FD6C4E (class_id), 
        add constraint FKF3371A1B51FD6C4E 
        foreign key (class_id) 
        references Class (id)
