hibernate的开发步骤示例

1.导入jar（hibernate+mysql)。
2.建表。
3.安装Jboss中的hibernate tools。
4.建hibernate.cfg.xml。（记得mapping model进去。，去掉session-factory的name属性 ）
5.调用hibernate API编程。

create database t2;
create table person (id int not null auto_increment,
    name varchar(100),
    age  int,
    primary key(id)
);
