JAVA按模版导出Word文档（无需转换word格式）

1. 设置word导出模版

注：Word文档中以 {{字段名}} 标记需替换的字段位置

2. java代码

Word文档导出工具类 WordTemplateUtil

importorg.apache.poi.xwpf.usermodel.*;importorg.springframework.core.io.ClassPathResource;importjavax.servlet.http.HttpServletResponse;importjava.io.InputStream;importjava.io.OutputStream;importjava.net.URLEncoder;importjava.util.List;importjava.util.Map;publicclassWordTemplateUtil{publicstaticvoidexportWord(StringtemplatePath,Map<String,Object>map,HttpServletResponseresponse,StringfileName)throwsException{ClassPathResourceresource=newClassPathResource(templatePath);InputStreamin=resource.getInputStream();XWPFDocumentdoc=newXWPFDocument(in);// 替换段落replaceAllParagraphs(doc.getParagraphs(),map);// 替换表格for(XWPFTabletable:doc.getTables()){for(XWPFTableRowrow:table.getRows()){for(XWPFTableCellcell:row.getTableCells()){replaceAllParagraphs(cell.getParagraphs(),map);}}}response.setContentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document");response.setCharacterEncoding("UTF-8");fileName=URLEncoder.encode(fileName,"UTF-8");response.setHeader("Content-Disposition","attachment;filename="+fileName);OutputStreamout=response.getOutputStream();doc.write(out);out.flush();out.close();doc.close();in.close();}/** * 替换段落变量，保留原字体格式 */privatestaticvoidreplaceAllParagraphs(List<XWPFParagraph>paragraphs,Map<String,Object>map){for(XWPFParagraphparagraph:paragraphs){StringBuilderfullText=newStringBuilder();for(XWPFRunrun:paragraph.getRuns()){Stringtext=run.getText(0);if(text!=null)fullText.append(text);}Stringcontent=fullText.toString();if(content.isEmpty())continue;// 替换 {{key}}for(Map.Entry<String,Object>entry:map.entrySet()){Stringkey="{{"+entry.getKey()+"}}";Objectvalue=entry.getValue()==null?"":entry.getValue();content=content.replace(key,value.toString());}// 保留第一个run的格式，清空其他List<XWPFRun>runs=paragraph.getRuns();if(runs.isEmpty())return;for(inti=runs.size()-1;i>0;i--){paragraph.removeRun(i);}// 重新赋值，格式不变XWPFRunfirstRun=runs.get(0);firstRun.setText(content,0);}}}

调用示例

@GetMapping("/export")publicvoidexport(HttpServletResponseresponse)throwsException{Map<String,Object>data=newHashMap<>();data.put("name","张三");data.put("age","35");StringfileName="模版导出.docx";// 模板在 resources/templates/WordTemplateUtil.exportWord("templates/wrzl.docx",data,response,fileName);}

2.前端js调用示例
