java - Spring MVC : Tying session attributes to each browser tab

Question

• 我正在开发 Spring-MVC 应用程序，我正在其中设置和获取我在后端需要的一些 session 属性。问题是，Spring 或浏览器，两者中有人正在捆绑这些 session 属性到不同的浏览器而不是不同的选项卡。
  • 因此，如果我在同一个浏览器中打开一个新选项卡，那么它会更新两个选项卡的 session 属性。我该如何解决这个问题？我尝试使用 session 来确定范围、请求等。但没有任何效果。这是我的 Controller 和 servlet-context.xml

Controller :

@Controller
@Scope("request")
public class PersonController {


    @Secured("ROLE_USER")
    @RequestMapping(value = "/loadsection/{id}")
    public String loadNotePage(@PathVariable("id") Integer id, HttpSession session) {
// here i am setting the canvasid, which I would like to access in other methods
        session.setAttribute("canvasid",id);
        if (this.personService.returnCurrentOperationalMode()) {

            session.setAttribute("canvasid",id);
            return "redirect:/section/listing";
        } else {
            GroupCanvas mcanvas = this.groupCanvasService.getCanvasById(id);
            this.personService.setCurrentCanvas(mcanvas.getMcanvasid());

            return "redirect:/section/listing";
        }

    }


    @Secured("ROLE_USER")
    @RequestMapping(value = "/addbatchsections", method = RequestMethod.POST)
    public @ResponseBody String addBatchSections(HttpSession session, @RequestBody Section[] sections) {
        int canvasid = (Integer) session.getAttribute("canvasid");
        try {
            List<Section> sectionList = new ArrayList<>();
            for (Section section : sections) {
                sectionList.add(section);
            }
            this.sectionService.addBatchSections(sectionList,canvasid);
            return "success";
        } catch (Exception e) {
            return "failure";
        }
    }

Servlet-Context.xml

我希望我的问题很清楚，如果有任何疑问，请随时问我。非常感谢。 :-)

看看Spring Session及其相关示例。
