Hibernate框架下向mysql中写入中文乱码解决方案

         最近搜集了2005年至2012年所有在我们国家登陆的有名称记载的台风数据，加之前段时间刚刚学习了Hibernate框架，因此想将这个数据做一个简单的入库存放至mysql当中，但是将一些中文值存入至数据库中时候为出现乱码问号，在网上搜集了一下解决办法，大多数说修改mysql的配置文件，经过尝试还是没办法解决问题，后来发现需要在控制台中用命令行才能解决。具体方法如下：

      1）首先在命令行中输入show variables like “%char%”;     

      2 ）依次输入set names utf8;

      ALTER DATABASE `db_name` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

      ALTER TABLE `tb_name` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;这样以后按理说应该已经解决问题了，经过测试发现从程序中写进去依旧是问号，         但是在数据库中直接修改则可以保存为中文；因此可以断定不是mysql的问题了；

      经查发现是Hibernate框架的编码问题，只要在hibernate.cfg.xml中添加

      就可以解决问题啦。

PS:刚才开始学习，所以水平难免不登台面，希望能请各位牛人多多指点！
