Question

spring mvc controller可以用Map接收jsp传来的值么

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";
		}
	}

不可以，map不具有封装性，尽量使用request封装一个对象接收
