1.1.1分类
在hibernate的配置文件中，session-factory的配置下，分为三类
- 连接配置：配置连接的参数
- 其他配置：配置其他的需求，例如打印sql语句，自动建表
- 映射配置：配置具体类的映射文件
需要注意的是proterty字段需要在mapping字段之前
Demo：
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory name="foo">
<!-- 数据库连接配置 -->
<!-- 连接类 -->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<!-- 连接数据库 -->
<property name="hibernate.connection.url">jdbc:mysql:///hi</property>
<!-- 连接用户名 -->
<property name="hibernate.connection.username">root</property>
<!-- 连接密码 -->
<property name="hibernate.connection.password">root</property>
<!-- 数据库方言 -->
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> <!-- 其他配置 -->
<property name="hibernate.show_sql"></property>
<property name="hibernate.hbm2ddl.auto">create</property> <!-- 加载所有的映射 -->
<mapping resource="per/liyue/code/hibernatehello/Employee.hbm.xml"/>
</session-factory>
</hibernate-configuration> 1.1.2分类
其中在其他配置项中可以配置创建或者更新的属性：
- 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！
1.1.3不使用配置文件生成表
在hibernate.cfg.xml中，可以设定属性为自动生成表，但是这种加载方式在调用配置文件的时候才会生效，如果要按需加载。则需要用代码手动来实现。
<!-- 将下面配置语句注释 -->
<property name="hibernate.hbm2ddl.auto">create</property>具体做法是在配置文件中注释自动生成的配置语句
package per.liyue.code.hibernatehello;
import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
import org.junit.Test;
public class AppMuanal {
@Test
public void CreateTableManual(){
//创建配置对象
Configuration con = new Configuration(); //加载配置文件
con.configure(); //获取工具类来实现创建表
SchemaExport schemaExport = new SchemaExport(con);
/*
* create的第一个参数表示是否显示sql语句
* create的第二个参数表示是否创建表
*/
schemaExport.create(true, true); }
} 1.2教程
常用的配置在教程hibernate-distribution-3.6.0.Final\project\etc\hibernate.properties中。下面是内容
