jsp和mysql连接
##########################################################################
中文问题：
jsp和mysql连接的时候，要在每一个jsp文件中加：
<%@ page contentType="text/html;charset=gb2312" %>
如果是表单的提交要加上：
jdbc:mysql://127.0.0.1:3306/publish?useUnicode=true&characterEncoding=GBK" 和
<% request.setCharacterEncoding("GBK"); %>
