ibatis2.3+mysql5.1+resin3.15乱码感想

今天整了一天了。发下感慨.
1.我的数据库，表都是utf-8
2.后来我在resin中也加上了
 <web-app id="/resin-admin" root-directory="${resin.home}/php/admin">
        <!--
           - Administration application /resin-admin
          -->
   <character-encoding>utf-8</character-encoding>
        <prologue>
          <resin:set var="resin_admin_external" value="false"/>
          <resin:set var="resin_admin_insecure" value="true"/>
        </prologue>
      </web-app>
还是不行
3.最后查到:
url=jdbc:mysql://localhost:3306/7cskycms?useUnicode=true&amp;characterEncoding=UTF-8
这样才行
url=jdbc:mysql://localhost:3306/7cskycms?characterEncoding=UTF-8
