jdbc插入不了数据

RegisterServlet代码：

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		response.setContentType("text/html");
		PrintWriter out = response.getWriter();
		request.setCharacterEncoding("UTF-8");
		response.setContentType("text/html;charset=UTF-8");
		
		//获取注册信息
		UserDao userdao=new UserDao();
		
		String userID=request.getParameter("phone");
		String username = request.getParameter("uname");
		String password = request.getParameter("pwd");
		String email = request.getParameter("mail");
		String sex = request.getParameter("sex");
		String birth=request.getParameter("birth");
		String address=request.getParameter("address");
		
		//可以传值
		/*out.println(userID);
		out.println(username);
		out.println(password);
		out.println(email);
		out.println(sex);
		out.println(address);
		out.println(birth);*/
		
		
		//将注册信息存入数据库，再返回登录
		userdao.Register(userID,username,password,birth,email,sex,address);
        response.sendRedirect("Login.jsp");
		
	}

UserDao的register代码段

public void Register(String userID, String userPsw, String userName, String email,String birth,String sex,String address) {
		// TODO Auto-generated method stub
		        //连接数据库
		        Connection conn = DBConnection.getConnection();
				//sql语句
				//String sql = "insert  into user(flag,userID,userPsw,userName,birth,E-mail,sex,address) values(?,?,?,?,?,?,?,?)";
				String sql="insert into user(userID,userName,userPsw,bitrh,E-mail,sex,address,flag) values(?,?,?,?,?,?,?,?)";
		        int rs = 0;
				PreparedStatement stm = null;
				try {
					//预编译SQL，减少sql执行
					stm = conn.prepareStatement(sql);
					//传参
					stm.setInt(8, 1);//状态->用户注册所以全为1
					stm.setString(1, userID);//手机号
					stm.setString(3, userPsw);//密码
					stm.setString(2, userName);//用户名
					stm.setString(5, email);//电子邮箱
					stm.setString(4, birth);//出生日期
					stm.setString(6, sex);//性别
					stm.setString(7, address);//收货地址
					//执行更新
					rs = stm.executeUpdate();
					
				} catch (Exception e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				try {
					stm.close();
					conn.close();
				} catch (Exception e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				
			
	}

• 点击注册后user表没有新记录，但会跳转到Login.jsp
• register页面传过来的值也能接收到
• 数据库已经连接好了，因为登录页面是没问题的，可以找到用户。
• 点了注册提交之后，数据库没有新记录产生。

checkErrorPacke:你的register（。。。）参数不对应，调用传入的参数 和 实现设置的参数名位置错了

报什么错，复制出来

String userID=request.getParameter("phone");         String username = request.getParameter("uname");         String password = request.getParameter("pwd");         String email = request.getParameter("mail");     String sex = request.getParameter("sex");String birth=request.getParameter("birth"); String address=request.getParameter("address");

能不能直接set进User ，加个构造器，注册直接传入User,可以避免很多错误，然后一个个get
