Answer 1

可以的，如下项目中的例子：

/**
     * 跳转到徙木贷款记账复核
     * @param model
     * @param params
     * @param request
     * @param response
     * @return
     */
    @RequestMapping("/loanVerRecordEdit.htm")
    public String toLoanVerRecordEdit(Model model,@RequestParam Map<String, Object> params, HttpServletRequest request,
            HttpServletResponse response){
        logger.info(">>>跳转到徙木贷款记账复核");
        String type = params.get("type").toString();
        try {
            Long id = Long.parseLong(params.get("id").toString());
            String loanNo = params.get("loanNo").toString();
            CustomerInfoRequest param = new CustomerInfoRequest();
            param.setLoanNo(loanNo);
            Map<String, Object> map = customerInfoService.queryLoanIouDetail(param);
            // 1.借据详情信息
            IolDetail iolDetail = (IolDetail) map.get("iolDetail");
            //还款信息
            LoanVerRecordResponse result = loanVerRecordService.getLoanDetailById(id);
            if (result == null) {
                result = new LoanVerRecordResponse();
                result.setReturnDate(new Date());
            }
            if (result.getReturnDate() == null) {
                result.setReturnDate(new Date());
            }
            model.addAttribute("iolDetail", iolDetail);
            model.addAttribute("loanVerRecord", result);
        } catch (Exception e) {
            logger.error("跳转到徙木贷款记账复核错误:" + e);
        }
        if ("1".equals(type)) {
            return "loan_ver_record/loanVerRecord_edit";
        } else {
            return "loan_ver_record/loanVerRecord_detail";
        }
    }
