总结之数据导出到word模板——使用poi导出
我们先看看需求：
我们要在模板标题插入内容，在多个表格中填充数据
先看东西
这里我写了个poi工具类方便操作

解析
public XWPFDocument exportListDoc(InputStream in, List>> data,String specialName) {
Map map = new LinkedHashMap();
map.put("${special}", specialName);
XWPFDocument doc = Word2007Util.replaceWord(map, in);
docList(data, doc);
return doc;
}
这块来替换word中${}数据
得到多个表格对象
List tables = doc.getTables();
通过List
然后获取表格，填充内容，设置样式。
//获取表格行对象
XWPFTableRow row = null;
row = table.createRow();
XWPFTableCell cell0 = row.getCell(0);
Word2007Util.setCellStyle(cell0, StringUtil.parseString(i + 1),"仿宋");
