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'?>
