Hibernate动态映射表名

很久以前的文档，今天特记录之

首先定义命名策略：

import java.util.Locale;

import org.hibernate.cfg.DefaultNamingStrategy;
import org.hibernate.cfg.NamingStrategy;
import org.hibernate.util.StringHelper;

public class LocalNamingStrategy extends DefaultNamingStrategy { 

    /**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	public static final NamingStrategy INSTANCE = new LocalNamingStrategy(); 

    protected LocalNamingStrategy() { 
    } 

    public String classToTableName(String className) {

    	String name = StringHelper.unqualify(className);
    	
    	
    	String language = Locale.getDefault().getLanguage();
    	
    	return addUnderscores(name + "_" + language);
    } 

    public String tableName(String tableName) { 
        return tableName; 
    } 

    public String columnName(String columnName) { 
        return columnName; 
    } 

    private String addUnderscores(String name) { 
        StringBuffer buf = new StringBuffer(name.replace('.', '_')); 
        for (int i = 1; i < buf.length() - 1; i++) { 
            if ('_' != buf.charAt(i - 1) && Character.isUpperCase(buf.charAt(i)) && !Character.isUpperCase(buf.charAt(i + 1))) { 
                buf.insert(i++, '_'); 
            } 
        } 
        return buf.toString().toLowerCase(); 
    } 

}

配置spring

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

    <description>xmrz</description> 
    
    <bean id="dataSource"
          class="com.rosy.common.config.SettingDataSource">
    </bean>  
    
    <bean id="sessionFactory"
          class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
            destroy-method="close"  > 
        <property name="namingStrategy" ref="namingStrategy"/><!—加入命名策略-->
        <property name="dataSource">
            <ref local="dataSource"/>
        </property>
        <property name="mappingResources">
……
</bean>
<!—定义命名策略bean -- >
<bean id="namingStrategy" class="com.rosy.common.dao.LocalNamingStrategy"/>
…..

配置hbm文件：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
                                   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- 
	Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
 <class name="com.rosy.system.database.PubBaseCode">
（去掉了映射是的table=” pub_base_code”）
  <id name="code" type="java.lang.String">
   <column length="15" name="code"/>
   <generator class="assigned"/>
  </id>
  <property generated="never" lazy="false" name="codeName" type="java.lang.String">
   <column length="20" name="code_name"/>
  </property>
 </class>
</hibernate-mapping>

能给发一个样例吗？第一次用，不太了解怎么用

这是很久之前的文档了，我也没有具体的示例，不过总的思路是第一个动态表映射的策略，在sessionFactory中采用这种策略就好了
