自己的例子：

public void wordExportOut(HttpServletResponse response){int row = 10;int column = 10;//新建一个文档XWPFDocument doc = new XWPFDocument();CTDocument1 document = doc.getDocument();CTBody body = document.getBody();if (!body.isSetSectPr()) {body.addNewSectPr();}CTSectPr section = body.getSectPr();if(!section.isSetPgSz()) {section.addNewPgSz();}CTPageSz pageSize = section.getPgSz();//必须要设置下面两个参数，否则整个的代码是无效的pageSize.setW(BigInteger.valueOf(15840));pageSize.setH(BigInteger.valueOf(12240));pageSize.setOrient(STPageOrientation.LANDSCAPE);//创建一个表格XWPFTable table = doc.createTable(row,column);//测试数据for (int i = 0; i < row; i++) {for (int j = 0; j < column; j++) {table.getRow(i).getCell(j).setText(""+i+":"+j);}}String fileName = "我的.doc";//设置相应头try {try {fileName = URLEncoder.encode(fileName, "UTF-8");} catch (UnsupportedEncodingException e) {e.printStackTrace();}response.setContentType("application/octet-stream;charset=UTF-8");response.setHeader("Content-Disposition", "attachment;filename="+ fileName);//遵守缓存规定response.addHeader("Pargam", "no-cache");response.addHeader("Cache-Control", "no-cache");} catch (Exception ex) {ex.printStackTrace();}//输出流OutputStream os = null;try {os = response.getOutputStream();doc.write(os);os.flush();os.close();} catch (IOException e) {e.printStackTrace();}}

工具类使用方式

String titleStr = "标题";
String description = "描述";
String[] value_columns = {"列1", "列2", "列3","列4","列5","列6","列7","列8"};
List<List<String>> dataList = new ArrayList<>();//导出的数据
Integer[] colWidths = {600,1700,2200,700,900,1500,7350,1050};//导出的excel宽度excel(扣除边距剩余共16000宽)
