这篇文章主要为大家展示了“Hibernate 如何配置”，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让丸趣 TV 小编带领大家一起研究并学习一下“Hibernate 如何配置”这篇文章吧。

1、Hibernate.cfg.xml 主配置

Hibernate.cfg.xml 是主配置文件，其中配置大体分为 3 部分：数据库连接信息、其他参数、映射信息！

!DOCTYPE hibernate-configuration PUBLIC
  -//Hibernate/Hibernate Configuration DTD 3.0//EN 
  http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd 
 hibernate-configuration 
  !--  通常，一个 session-factory 节点代表一个数据库  -- 
  session-factory 
  !-- 1.  数据库连接配置  -- 
  property name= hibernate.connection.driver_class com.mysql.jdbc.Driver /property 
  property name= hibernate.connection.url jdbc:mysql:///test /property 
  property name= hibernate.connection.username root /property 
  property name= hibernate.connection.password root /property 
 !-- 
 数据库方言配置， hibernate 在运行的时候，会根据不同的方言生成符合当前数据库语法的 sql
  -- 
  property name= hibernate.dialect org.hibernate.dialect.MySQL5Dialect /property 
 
  !-- 2.  其他相关配置  -- 
 !-- 2.1  显示 hibernate 在运行时候执行的 sql 语句  -- 
 property name= hibernate.show_sql false /property 
 !-- 2.2  格式化 sql -- 
 property name= hibernate.format_sql true /property 
 !-- 2.3  自动建表  -- 
 property name= hibernate.hbm2ddl.auto update /property 

 !-- 3.  加载所有映射  -- 
 mapping resource= com/rk/hibernate/a_hello/Employee.hbm.xml / 
  /session-factory 
 /hibernate-configuration

1.1、数据库连接参数配置 

## MySQL
#hibernate.dialect org.hibernate.dialect.MySQLDialect
#hibernate.dialect org.hibernate.dialect.MySQLInnoDBDialect
#hibernate.dialect org.hibernate.dialect.MySQLMyISAMDialect
#hibernate.connection.driver_class com.mysql.jdbc.Driver
#hibernate.connection.url jdbc:mysql:///test
#hibernate.connection.username gavin
#hibernate.connection.password

1.2、自动建表 

#hibernate.hbm2ddl.auto create-drop  每次在创建 sessionFactory 时候执行创建表；当调用 sesisonFactory 的 close 方法的时候，删除表！#hibernate.hbm2ddl.auto create  每次都重新建表；  如果表已经存在就先删除再创建
#hibernate.hbm2ddl.auto update  如果表不存在就创建；  表存在就不创建；#hibernate.hbm2ddl.auto validate (生成环境时候)  执行验证：  当映射文件的内容与数据库表结构不一样的时候就报错！

根据 hibernate.cfg.xml 文件自动建表 

import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class App
 public static void main(String[] args)
 //  创建配置管理类对象
 Configuration config = new Configuration();
 //  加载主配置文件
 config.configure();
 //  创建工具类对象
 SchemaExport export = new SchemaExport(config);
 //  建表
 //  第一个参数：  是否在控制台打印建表语句
 //  第二个参数：  是否执行脚本
 export.create(true, true);
}

1.3、常用配置参考文件

常用配置参考文件：hibernate-distribution-3.6.0.Final\project\etc\hibernate.properties
