java - Spring MVC怎么实现提交表单后跳转？
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" %>
<html><head><title>添加</title></head>
<body>
<form method="post" action="/items/add.action">
输入姓名<input name="username" type="text" id="txtname"><br>
输入邮箱<input name="useremail" type="text" id="txtemail"><br>
<input type="submit" value="录入" >
</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>查询</title></head>
<body>
<h1>用户列表</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类
@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;
}
}
