Question

class Workshop {
    constructor(name, desc) {
      this.name = name;
      this.desc = desc;
    }

    getWork() {
      console.log(this.name + " " + this.desc);
    }
}

class Session extends Workshop {
    constructor(name, desc, time){
        super(name, desc);
        this.time = time;
    }
    getSession() {
        console.log(this.name + " " + this.desc + " " + this.time);
    }
    changeTime(newTime) {
        let delta = this.time - newTime;
        this.time = newTime;

    }
}

let sessionList = [
    sess1 = new Session('hummus', 'yamyam', 45),
    sess2 = new Session('Kabab', 'mmmmmm', 70)
]

sessionList.forEach((session) => {
    console.log(session.time);
});

我正在尝试将用户转发/重定向到新的JSP文件，我可以转到@RequestMapping(value = { "postCustomer" }, consumes = "application/json", method = {RequestMethod.POST}) public ModelAndView postHome(@RequestBody JSONObject body, Model model) throws JSONException { ModelAndView mav = new ModelAndView("redirect:/feasibility"); return mav; } @GetMapping(value = { "feasibility" }) // GET MAPPING public String feasibility(ModelAndView model) throws Exception { return "feas"; }并进行更新，但是当我发布<url>/feasibility时，它不会重定向或更新视图。我也尝试过使用JSP“ feas”创建一个postCustomer，然后在ModelAndView中返回它，但这也不起作用。我不确定是否遗漏了明显的内容，还是必须执行其他步骤来更新视图。

如果任何人有任何建议或解决方案，我将不胜感激。

重定向将被视为新请求，尝试转发该请求

重定向和转发不是同一件事

    @RequestMapping(value = { "postCustomer" }, consumes = "application/json", method = {RequestMethod.POST})
public ModelAndView postHome(@RequestBody JSONObject body, Model model) throws JSONException {
    ModelAndView mav = new ModelAndView("forward:/feasibility");
    //data to forward
    mav.addAttribute("data", data);
    return mav;
}

ModelAndView不更改视图
