Hibernate 环境配置和依赖添加(使用java web和普通javaSE工程)

1.Hibernate依赖包的添加

File---->Project Structure,按照如图所示操作,导入所依赖的jar包。

2.生成hibernate.hbm.xml的配置文件

(1)点击File,弹出的菜单中点击Project Structure;

(2)点击左侧的Modules,再点击“+”号,再在弹出的菜单中选择Hibernate;

(3)在这时,项目中多出了一个Hibernate,点击Hibernate,再点击“+”号,选择hibernate.hbm.xml;

(4)弹出的窗口中选择Hibernate的版本,然后点击OK;

(5)这时项目架子中多出了一个名为hibernate.hbm.xml的配置文件;

3.配置数据库

(1)点击左下角按钮,使窗口样式如图所示;

 (2)选择数据库;

(3)配置数据库后测试连接是否成功,若成功后点击确定;

4.生成Hibernate的实体类以及配置文件

(1)点击窗口中的Persistence;

(2)选择数据源,配置实体类包,选择要生成的实体类(其中日期类型的只能手动修改为java.util.Date),然后点击OK

(2)点击ok,后会生成如下内容

hibernate.cfg.xml文件配置如下:

<?xml version='1.0' encoding='utf-8'?>
