我想在addItem的頁面輸入了信息之后點(diǎn)提交，可以提交表單然后跳轉(zhuǎn)到queryItems的頁面。請(qǐng)問要怎么寫？是在Controller里寫還是在JSP頁面里寫？
基礎(chǔ)問題，剛開始學(xué)，求回答，非常感謝。

兩個(gè)Jsp頁面:
addItem.jsp

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html><head><title>添加</title></head>
<body>
<form method="post" action="/items/add.action">
    輸入姓名<input name="username" type="text" id="txtname"><br>
    輸入郵箱<input name="useremail" type="text" id="txtemail"><br>
    <input type="submit" value="錄入" >
</form>
</body>
</html>

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"%>
<!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>查詢</title></head>
<body>
<h1>用戶列表</h1>
<form action="/items/query.action" method="get">
    <c:forEach var="user" items="${userList}">
        <c:out value="${user.user_name}"/>
        ----<c:out value="${user.user_email}"/>
        <br>
    </c:forEach>
</form>
</body>
</html>

我的Controller類

@Controller
@RequestMapping("/items")
public class ItemsController {
    @Autowired
    private ItemsService itemsService;
    
    @RequestMapping("/query")
    public ModelAndView queryItems() throws Exception{
        List<User> 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;
    }
}
