我想在addItem的页面输入了信息之后点提交，可以提交表单然后跳转到queryItems的页面。请问要怎么写？是在Controller里写还是在JSP页面里写？
基础问题，刚开始学，求回答，非常感谢。

两个Jsp页面:
addItem.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>



    输入姓名

    输入邮箱

    

queryItems.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt"  prefix="fmt"%>



用户列表

我的Controller类

@Controller
@RequestMapping("/items")
public class ItemsController {
    @Autowired
    private ItemsService itemsService;
    
    @RequestMapping("/query")
    public ModelAndView queryItems() throws Exception{
        List itemsList = itemsService.findAllUser();
        ModelAndView mv = new ModelAndView();
        mv.addObject("userList", itemsList);
        mv.setViewName("queryItems");
        return mv;

    }
    @RequestMapping("/add")
    public ModelAndView addItem(String username, String useremail) throws Exception{
        User user = new User();
        user.setUser_name(username);
        user.setUser_email(useremail);
        itemsService.insertUser(user);
        ModelAndView mv = new ModelAndView();
        mv.addObject(user);
        mv.setViewName("addItem");
        return mv;
    }
}
