编写HibernateUtil辅助类获取sessionFactory

[java] view plain copy

测试类

[java] view plain copy

public class TestPersister {
private static AbstractEntityPersister classMetadata;
private Object obj;
public TestPersister(SessionFactory sessionFatory, Object obj) {
classMetadata = (AbstractEntityPersister) sessionFatory.getClassMetadata(obj.getClass());
this.obj = obj;
}
/**
* @param args
*/
public static void main(String[] args) {
//实例化classMetadata 传入sessionFactory和obj对象
TestPersister tp = new TestPersister(HibernateUtils.getSessionFactory(),new HhArticle());
Session session = HibernateUtils.getSessionFactory().getCurrentSession();
session.beginTransaction();
SQLQuery sqlquery = session.createSQLQuery("DELETE FROM " + classMetadata.getTableName());
sqlquery.executeUpdate();
session.getTransaction().commit(); //事务提交
//classMetadata一些其他操作
System.out.println(classMetadata.getTableName()); //表名
System.out.println(classMetadata.getIdentifierPropertyName()); //主键列映射属性
System.out.println(classMetadata.getEntityName()); //对象名称
for(String str:classMetadata.getPropertyNames()){ //非主键属性
System.out.println(str);
}
}
public AbstractEntityPersister getClassMetadata() {
return classMetadata;

public void setClassMetadata(AbstractEntityPersister classMetadata) {
this.classMetadata = classMetadata;
}
public Object getObj() {
return obj;
}
public void setObj(Object obj) {
this.obj = obj;
}
}
