使用POI3.15操作Word2013，包括表格、段落的读写。

1、读取文件

private static XWPFDocument read_file(String srcPath)
        {
            String[] sp = srcPath.split("\\.");
            if ((sp.length > 0) && sp[sp.length - 1].equalsIgnoreCase("docx"))
            {
                try {
                    OPCPackage pack = POIXMLDocument.openPackage(srcPath);
                    XWPFDocument doc = new XWPFDocument(pack);
                    return doc;
                } catch (IOException e) {
                    System.out.println("读取文件出错！");
                    e.printStackTrace();
                    return null;
                }
            }
            return null;
        }

2、插入文字与表格，文档至少有一点内容，换行符也可以。

private static XWPFDocument insertParagraph(XWPFDocument document){
            Iterator<XWPFParagraph> itPara = document.getParagraphsIterator();
            int ind = 1;
            //获取段落位置
            while (itPara.hasNext()) {
                XWPFParagraph paragraph = (XWPFParagraph) itPara.next();
                XWPFRun xrun = paragraph.createRun();
                xrun.setText("这是第"+ ind++ +"个段落！");
    
                //插入表格
                XmlCursor cursor = paragraph.getCTP().newCursor();
                XWPFTable tb = document.insertNewTbl(cursor);
                //行
                XWPFTableRow row = tb.getRow(0);
                row.addNewTableCell();
                row.getCell(0).setText("0");
                row.getCell(1).setText("1");
            }
            return document;
        }

3、遍历文档内容

private static XWPFDocument readPar(XWPFDocument document){
            Iterator<XWPFParagraph> itPara = document.getParagraphsIterator();
            while (itPara.hasNext()) {
                XWPFParagraph paragraph = (XWPFParagraph) itPara.next();
                //run表示相同区域属性相同的字符，结果以‘，’分隔；
                List<XWPFRun> runs = paragraph.getRuns();
                for (int i = 0; i < runs.size(); i++)
                {
                    String oneparaString = runs.get(i).getText(runs.get(i).getTextPosition());
                    System.out.println(oneparaString);
                }
            }
            return document;
        }

4、文档写入磁盘

private static void writeDoc(XWPFDocument document,String path){
            FileOutputStream fOut = null;
            try {
                fOut = new FileOutputStream(path);
                document.write(fOut);
                fOut.close();
                fOut = null;
            } catch (Exception e) {
                e.printStackTrace();
            }

5、遍历表格，如果是新增的表格先写入磁盘再读取，否则读取的内容为空。

private static void readTableContent(XWPFDocument document){
            Iterator<XWPFTable> itTable = document.getTablesIterator();
            int ind = 0;
            while (itTable.hasNext()){
                ind++;
                XWPFTable table = (XWPFTable) itTable.next();
                //行
                int rcount = table.getNumberOfRows();
                for (int i = 0; i < rcount; i++){
                    XWPFTableRow row = table.getRow(i);
                    //列
                    List<XWPFTableCell> cells = row.getTableCells();
                    int len = cells.size();
                    for(int j = 0;j < len;j++){
                        XWPFTableCell xc = cells.get(j);
                        String sc = xc.getText();
                        System.out.println("第"+ ind +"个表格，第"+ (i+1) +"行，第"+ (j+1) +"列：" +sc);
                    }
                }
            }
        }
