解决hibernate+mysql写入数据库乱码

           hibernate.cfg.xml加上属性.
<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">UTF-8</property>
mysql 的驱动用3.0.15以上版本的,
加个Filter, 使用UTF-8字符集就可以了,
若使用Spring则写在spring中的sessionFactory里即可。
例如：
<?xml version='1.0' encoding='UTF-8'?>
