SSM报错：java.sql.SQLException: 无效的列类型: 1111

居然没写传值：

@RequestMapping(value="/reg.action")
public void reg(HttpServletRequest req,HttpServletResponse resp) throws UnsupportedEncodingException{
req.setCharacterEncoding("utf-8");
String userName=req.getParameter("userName");
String userPwd=req.getParameter("userPwd");
String userEmail=req.getParameter("userEmail");
UserInfo u=new UserInfo();
String userId=DBHelp.getString();
//System.out.println(userId+"iii");
<span style="color:#ff0000;">u.setUserId(userId);</span>
u.setUserName(userName);
u.setUserPwd(userPwd);
u.setUserEmail(userEmail);

真是操蛋，下次注意！
