使用springboot的thymeleaf在前端获取数据，使用model和session前端都获取不到。
InfoController.java
package com.example.h1.controller;
import com.example.h1.domain.User;
import com.example.h1.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;
@Controller
public class InfoController extends HttpServlet {
@Autowired
public UserService userService;
//查询并返回页面
// @RequestMapping("/info")
// public String list(Model model){
// List<User> list = userService.findAll();
// model.addAttribute("infor" , list);
// model.addAttribute("aaa","aaa");
// return "redirect:/static/infor.html";
// }
@RequestMapping("/info")
public String list(HttpServletRequest request, HttpServletResponse response) {
List<User> list = userService.findAll();
//添加session
request.getSession().setAttribute("infor",list);
System.out.println(request.getSession().getAttribute("infor"));
return "redirect:/static/infor.html";
}
}
这里我输出了一下session在控制台可以看到存入的数据。
infor.html

在网上找了好多，感觉可能是因为InfoController里使用return "redirect:/static/infor.html";跳转的原因。
但是在最早创建项目时就遇到了用return "infor";跳转不过去的问题，网页报错：
控制台报错：
所以才使用return "redirect:/static/infor.html";跳转。
有没有办法让使用return "redirect:/static/infor.html";跳转前端能获取到数据，或者怎么使用return "infor";跳转？
求带佬指导一下，谢谢！
