Hibernate 命名策略-优快云博客

本文介绍如何通过实现Hibernate的NamingStrategy接口来定制命名策略，包括类到表名、属性到列名等转换规则，并展示了具体的代码实现及配置方法。

定制自己的命名策略，必须要实现一个接口，或继承自这两个类

接口:org.hibernate.cfg.NamingStrategy;

类:org.hibernate.cfg.ImprovedNamingStrategy;

类:org.hibernate.cfg.DefaultNamingStrategy;

以下是实现了org.hibernate.cfg.NamingStrategy接口的代码

package cn.lxl.bean;

import org.hibernate.cfg.NamingStrategy;

public class Naming implements NamingStrategy {

	@Override
	public String classToTableName(String arg0) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String collectionTableName(String arg0, String arg1, String arg2,
			String arg3, String arg4) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String columnName(String arg0) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String foreignKeyColumnName(String arg0, String arg1, String arg2,
			String arg3) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String joinKeyColumnName(String arg0, String arg1) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String logicalCollectionColumnName(String arg0, String arg1,
			String arg2) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String logicalCollectionTableName(String arg0, String arg1,
			String arg2, String arg3) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String logicalColumnName(String arg0, String arg1) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String propertyToColumnName(String arg0) {
		// TODO Auto-generated method stub
		return arg0+"lxl";
	}

	@Override
	public String tableName(String tableName) {
		// TODO Auto-generated method stub
		return tableName+"lxl";
	}

}

根据自己的需要实现上面的方法，实现自己的目标

类写好了，怎么生效了

Configuration cfg=new Configuration().setNamingStrategy(new Naming()).configure();

要写在创建SessionFactory对象之前
