请教大佬，我这段代码哪里出错了？

从表单获取数据出错
index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>主页</title>
</head>
<body>
<form action="/Text/add" method="psot">
<table>
<td>
用户id:<input name="userId" value="" type="text">
</td>
<td>
用户名:<input name="userName" value="" type="text">
</td>
<td>
密码:<input name="userPassword" value="" type="text">
</td>
<td>
<input value="提交" type="submit">
</td>
</table>
</form>
</body>
</html>

servlet层

package com.text.servlet.user;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.text.entity.user;
/**

@WebServlet("/Text/add")
public class add extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
//设置字符集
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=utf-8");
String userId = request.getParameter("userId");
String username = request.getParameter("userName");
String psw = request.getParameter("userPassword");
//创建用户实体类
user u = new user(userId, username, psw);
//连接数据库
System.out.print(u);
//重定向；
if(true) {
response.sendRedirect("/index.jsp");
}else {
PrintWriter out = response.getWriter();
out.write("<script>");
out.write("alert('用户注册失败')");
out.write("location.href='https://segmentfault.com/q/1010000039111198/insert.jsp'");
out.write("<script>");
}
}
}
