controller类:

  @GetMapping(value = "addOrUpdateSaleChancePage")
    public String addOrUpdateSaleChancePage(Integer id, Model model){
        if(null!=id){
            SaleChance saleChance = saleChanceService.getById(id);
            //设置到请求域
            model.addAttribute("saleChance",saleChance);
        }
        return "saleChance/add_update";
    }

前端取值:

<#--            指派人的隐藏域-->
            <input type="hidden" id="assignManId" value="${(saleChance.assignMan)!}"/>

一定要加 ! 号
