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：


  2. <!DOCTYPE hibernate-configuration PUBLIC
  3.     "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  4.     "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
  5. <hibernate-configuration>
  6.     <session-factory name="foo">
  7.         <!-- 数据库连接配置 -->
  8.         <!-- 连接类 -->
  9.         <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  10.         <!-- 连接数据库 -->
  11.         <property name="hibernate.connection.url">jdbc:mysql:///hi</property>

  13.         <property name="hibernate.connection.username">root</property>

  21.         <property name="hibernate.hbm2ddl.auto">create</property>
  23.         <!-- 加载所有的映射 -->
  24.         <mapping resource="per/liyue/code/hibernatehello/Employee.hbm.xml"/>
  25.     </session-factory>
  26. </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。

  1. <!-- 将下面配置语句注释 -->
  2. <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

  1. package per.liyue.code.hibernatehello;
  2. import org.hibernate.cfg.Configuration;
  3. import org.hibernate.tool.hbm2ddl.SchemaExport;
  4. import org.junit.Test;
  5. public class AppMuanal {
  6.     @Test
  7.     public void CreateTableManual(){
  8.         //创建配置对象
  9.         Configuration con = new Configuration();
  11.         //加载配置文件
  12.         con.configure();
  14.         //获取工具类来实现创建表
  15.         SchemaExport schemaExport = new SchemaExport(con);
  16.         /*
  17.          * create的第一个参数表示是否显示sql语句
  18.          * create的第二个参数表示是否创建表
  19.          */
  20.         schemaExport.create(true, true);
  22.     }
  23. }
