java实现以docx格式导出

直接上代码：
Map<String, Object> dataMap = afterLoanReportService.exportReport(startDate, endDate);
//new FtlToWordUtil().downContract(request, response, dataMap, "ABS产品贷后分析报告.doc", "ABS产品贷后分析报告.ftl");
String fileName = "ABS产品贷后分析报告.docx";
//电脑桌面路径
//String desktopUrl = FileSystemView.getFileSystemView().getHomeDirectory().getPath();
//xmlTemp:填充完数据的临时xml
String xmlTemp = tempUrl + "\" + fileName + ".xml";
File f = new File(xmlTemp);
Writer w = new FileWriter(f);

//1.把map中的数据动态由freemarker传给xml
XmlToExcel.process("ABS产品贷后分析报告.xml", dataMap, w);

//2.把填充完成的xml写入到docx中
XmlToDocx xtd = new XmlToDocx();

InputStream is = this.getClass().getResourceAsStream("/template/ABS产品贷后分析报告.docx");
xtd.outDocx(f, is, fileName, response, request);
return ResultModelUtil.getSucessData();
