java poi读取word树形表格

//melon-树形word进数据库
    @RequestMapping(value = "/test_word", method = RequestMethod.POST, produces = {"application/json;charset=utf-8"})
    @ResponseBody
    public String test_word(@RequestParam(value = "file", required = false) MultipartFile file) throws Exception {
        if (file.isEmpty()) {
            return NR.r(CodeDict.CODE_MESSAGE, -1, CodeDict.UPLOAD_EMPTY, null, null, 0, 0);
        } else {
            String fileName = setFile(file, "CheckItemWord\\");
            String path = System.getProperty("catalina.home") + "\\webapps\\CheckItemWord\\" + fileName;
            uploadService.testWord(path);
            return NR.r(CodeDict.CODE_MESSAGE, 1, 0, null, null, 0, 0);
        }
    }

操作整个word：

        List<XWPFParagraph> paras = doc.getParagraphs();

            //当前段落的属性
//       CTPPr pr = para.getCTP().getPPr();
           // System.out.println("段落属性："+para.getText());
        }
        //获取文档中所有的表格
        List<XWPFTable> tables = doc.getTables();
        List<XWPFTableRow> rows;
        List<XWPFTableCell> cells;
        for (XWPFTable table : tables) {
            //表格属性
//       CTTblPr pr = table.getCTTbl().getTblPr();
            //获取表格对应的行
            rows = table.getRows();
