参数膨胀问题

[ykstudy]

当json数据有多层次，并且上下层关系同名时，会出现匹配不到的问题。需要修改匹配逻辑

/**
     * param 格式为a.b.c:xxx
     * map 可以去掉，获取每次的map集合
     * appendMap 获取最终的map集合
     *
     * @param param
     */
    private void dot2Json(String param, Map map, Map appendMap) {
        if (null == map) {
            map = new HashMap<>();
        }
        String[] o = param.split(":");
        String[] split = o[0].split("\\.");
        // 值为空时，默认为空字符串
        String content = o.length >= 2 ? o[1] : StrUtil.EMPTY;
        Map<String, Object> resultMap = new HashMap<>();
        Map<String, Object> deepMap = appendMap;
        int deep = -1;
        for (int i = 0; i < split.length; i++) {
            if (i == split.length - 1) {
                resultMap.put(split[i], content);
            } else {
                Object obj = deepMap.get(split[i]);
                if (obj != null) {
                    if (obj instanceof Map) {
                        deepMap = (HashMap) obj;
                        deep = i;
                    }
                }
                resultMap.put(split[i], new HashMap<>());
            }
        }
        if (split.length > 1) {
            for (int i = split.length - 2; i >= 0; i--) {
// **这里会有问题**
                Map<String, Object> tempMap = (HashMap) resultMap.get(split[i]);
                tempMap.put(split[i + 1], resultMap.get(split[i + 1]));
                if (i == deep) {
                    deepMap.put(split[i + 1], resultMap.get(split[i + 1]));
                }
            }
            map.put(split[0], resultMap.get(split[0]));
            if (-1 == deep) {
                deepMap.put(split[0], resultMap.get(split[0]));
            }
        } else {
            map = resultMap;
        }
    }
