spring mvc redirect设置FlashAttribute

时间：2024-05-04 20:32:55

在Controller中设置：

    @RequestMapping("/redir")

    public String redir(Model model, RedirectAttributes ra) {

        ra.addFlashAttribute("test", "测试数据");

        return "redirect:/user/users";

    }

在jsp中使用el表达式接收：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<%

    String path = request.getContextPath();

    String basePath = request.getScheme() + "://"

            + request.getServerName() + ":" + request.getServerPort()

            + path + "/";

%>
