</html>下面是ServletUserRegister.java
package Servlet;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import Userbean.*;
public class ServletUserRegister {
public void doPost(HttpServletRequest request,HttpServletResponse response)throws ServletException, IOException{
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
//设置编码格式为UTF-8
String userName = request.getParameter("userName");
String userPassword = request.getParameter("password1");
String phoneNumber = request.getParameter("phoneNumber");
String userEmail = request.getParameter("userEmail");
//前台得到用户输入数据
UserVo user = new UserVo();
//实例化一个VO对象
user.setUserName(userName);
user.setPassword(userPassword);
user.setPhoneNumber(phoneNumber);
user.setUserEmail(userEmail);
//将前台得到的数据存入VO
UserDao userDao = new UserDao();
//实例化一个数据库对象
userDao.insertUser(user);
//调用增加用户方法
System.out.println("已添加");
request.getRequestDispatcher("/index.html").forward(request, response);
//转跳到登陆页面
}
}为什么之后运行就会出现了这个报错
是不是路径打错了
求！大神求助

servlet没有继承 404肯定是路径问题

路径：action="<%=request.getContextPath() %>/Servlet/ServletUserRegister"；
servlet:地址 @WebServlet("/Servlet/ServletUserRegister" )
