关于jsp<c:forEach>问题5

有两个东西要在同一个循环里面遍历出来！代码如下：

public ModelAndView searchList(HttpServletRequest request, String keyword,String province, Integer city, Integer game)
			throws UnsupportedEncodingException {
		Map<String, List> ul = new LinkedHashMap<String, List>();
		// 查询容器
		Map<String, Object> searchParams = new HashMap<String, Object>();
		Map<String, Object> searchKeyword = new HashMap<String, Object>();
		Map<String, Object> recommend = new HashMap<String, Object>();
		Map<String, Object> provincesParams = new HashMap<String, Object>();
		Map<String, Object> zone1 = new HashMap<String, Object>();
		provincesParams.put("layer", SysZone.PROVINCE);
		
		List<SysZone> provinces = sysZoneService.getSysZoneListByParams(provincesParams, null, null);

		// 根据26个字母开头循环
		String words = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
		for (char ch : words.toCharArray()) {
			searchParams.clear();
			searchParams.put("nametype", ch);
			List<SysGame> list = sysGameService.getSysGameListByParams(searchParams, null, null);
			ul.put(String.valueOf(ch), list);
		}
		
		RequestUtils requestUtils = new RequestUtils(request);
		Integer pageNum = requestUtils.getInt("pageNum", 0);
		Integer pageSize = requestUtils.getInt("pageSize", 10);
		PageCommand pageCommand = new PageCommand();
		pageCommand.setPageNum(pageNum);
		pageCommand.setPageSize(pageSize);

		
		List<SunCompetition> list = null;
		
		if (StringUtils.isNotBlank(keyword)) {
			searchKeyword.put("name", keyword);
			searchParams.put("name", keyword);
			pageCommand.setTotal(sunCompetitionService.getCountSunCompetitionByParams(searchParams));
			pageCommand.reload();
			OrderCommand orderCommand = new OrderCommand();
			List<String> params = new ArrayList<String>();
			List<String> models = new ArrayList<String>();
			params.add("signendtime");
			params.add("createtime");
			models.add("desc");
			orderCommand.addOrders(params, models);
			list = sunCompetitionService.getSunCompetitionListByParams(searchKeyword, orderCommand, pageCommand);
			
		} else {
			
			searchKeyword.put("game", game);
			searchKeyword.put("province", province);
			searchKeyword.put("city", city);
				
			searchParams.put("province", province);
			searchParams.put("city", city);
			searchParams.put("game", game);
			
			pageCommand.setTotal(sunCompetitionService.getCountSunCompetitionByParams(searchParams));
			pageCommand.reload();
			OrderCommand orderCommand = new OrderCommand();
			List<String> params = new ArrayList<String>();
			List<String> models = new ArrayList<String>();
			params.add("signendtime");
			models.add("desc");
			orderCommand.addOrders(params, models);
			list = sunCompetitionService.getSunCompetitionListByParams(searchKeyword, orderCommand, pageCommand);
			
			for (SunCompetition comp : list) {
				SysZone province1 = sysZoneService.getSysZoneById(comp.getProvince());
				SysZone city1 = sysZoneService.getSysZoneById(comp.getCity());
				zone1.put("province1", province1.getName());
				zone1.put("city1", city1.getName());
				System.out.println(city1.getName());
			}
		}
		recommend.put("recommend", 1);
		List<SunCompetition> recommendList = sunCompetitionService.getSunCompetitionListByParams(recommend, null, null);
		return new ModelAndView("/competition/search")
				.addObject("provinces", provinces)
				.addObject("gameList", ul)
				.addObject("searchList", list)
				.addObject("recommendList", recommendList)
				.addObject("keyword", keyword)
				.addObject("page", pageCommand)
				.addObject("searchKeyword", searchKeyword)
				.addObject("zone1",zone1);
	}

jsp页面遍历 list 时我想同时遍历zone1 求大神解释

遍历 <c:foreach>

看代码，你获取list是SunCompetition的集合，而zone1只是list最后一个SunCompetition的省名称和市名称？？？

不会是写错了吧？

我的理解你要遍历list并获取SunCompetition 的省、市名称？？？

按我的做法就是在SunCompetition中创建两个变量：provinceName、cityName；然后循环list获取provinceName、cityName并设置进去即可。

然后便利list就可获取provinceName、cityName
