解决 java循环中使用 Map时 在put值时value值被覆盖的问题

其实很简单，只需要把容器换成list

然后在循环中 每次循环末尾 或者直接在循环中实例化hashmap，这样就不会造成map覆盖了。

    @RequestMapping("controller/json/AssetsController/getAssetsInfosysAndType")
    @ResponseBody
    public Msg getAssetsInfosysAndType() {
        List list = new ArrayList();
        List<AssetsInfosys> assetsInfoSysServiceAll = assetsInfoSysService.getAll();
        List<AssetsStructureLowerMenu> lowerMenuServiceAll = assetsStructureLowerMenuService.getAll();
        for (AssetsInfosys ai :
                assetsInfoSysServiceAll) {
            for (AssetsStructureLowerMenu lmsa :
                    lowerMenuServiceAll) {
                if (ai.getName().equals(lmsa.getSuperiormenu())) {
                    Map map = new HashMap();
                    map.put("assetsInfoSys", ai);
                    map.put("msgAssetsType", lmsa);
                    list.add(map);
                }
            }
        }
        return Msg.success().add("AllMsgAssetsInfosysAndType", list);
    }
