2、处理方法

 public static List<List<String>> formatTxt(String txt) {

        String[] lineData = txt.split("\n");
        if (lineData.length == 1 || lineData == null) {
            lineData = txt.split("\r\n");
        }

        List<String> lineDataFeatures = Lists.newArrayList(lineData);
        List<List<String>> txtList = new ArrayList<>();
        List<Integer> indexList = new ArrayList<>();
        for (int i = 0; i < lineData.length; i++) {
            String line = lineData[i];
            if (line.contains("@")) {
                indexList.add(i);
            }
        }
        for (int i = 0; i < indexList.size(); i++) {
            if ((i + 1) == indexList.size()) {
                List<String> lineList = lineDataFeatures.subList(indexList.get(i), lineDataFeatures.size());
                txtList.add(lineList);
            } else {
                List<String> lineList = lineDataFeatures.subList(indexList.get(i), indexList.get(i + 1));
                txtList.add(lineList);
            }
        }
        return txtList;
    }
