Configuration cfg =
new
Configuration().configure();
SchemaExport export =
new
SchemaExport(cfg);
export.create(
true
,
true
);

二.Hibernate整合Spring
1.使用hibernate.cfg.xml原生配置
hibernate.cfg.xml同原生一样编写
在Spring主配置文件applicationContext中,引入hibernate.cfg.xml
使用SchemaExport生成数据库表的代码同上一致。

Spring applicationContext.xml
<
bean
id
=
"sessionFactory"
class
=
"org.springframework.orm.hibernate3.LocalSessionFactoryBean"
>
<
property
name
=
"configLocation"
value
=
"file:src/hibernate.cfg.xml"
>
</
property
>
</
bean

2.不使用hibernate.cfg.xml,在Spring的主配置文件applicationContext.xml中配置
完全不编写hibernate.cfg.xml,全部都在applicationContext.xml中配置

ClassPathResource ac =
new
ClassPathResource(
"applicationContext.xml"
);
XmlBeanFactory xbf =
new
XmlBeanFactory(ac);
//注意: &sessionFactory ,一定要包含 & ,不加Spring返回的是Hibernate下的SessionFactoryImpl类
LocalSessionFactoryBean lsfb=(LocalSessionFactoryBean) xbf.getBean(
"&sessionFactory"
);
Configuration cfg=lsfb.getConfiguration();
SchemaExport export=
new
SchemaExport(cfg);
export.create(
true
,
false
);
