一· 需要制作一个需要导出的word文档模板（使用wps导出xml（2003））然后将文件后缀名给为ftl----------------将文件xx.ftl放在后台代码的静态资源目录下（也就是template下）
将其正你所需要填写字段通过${字段名}代替
二·进行java代码的开发
@RestController
@AllArgsConstructor
@RequestMapping("/word")
public class WordExportController {
private IWordExportService iWordExportService;
/**
* 获取文档数据
*
* @param request 请求参数
* @param response 响应
*/
@PostMapping("detail")
你所需填入的数据对象通过request参数传入
public void wordExport(HttpServletRequest request, HttpServletResponse response) {
Map<String, Object> dataMap = new HashMap<>(20);
iWordExportService.getData(dataMap, request);
String dir = System.getProperty("user.dir");
String annualReportPath = dir + File.separator + "blade-service" + File.separator + "blade-word-export" + File.separator + "src" + File.separator + "main" + File.separator + "resources" + File.separator + "template";
File path = new File(annualReportPath);
if (!path.exists()) {
annualReportPath = dir + File.separator + "template";
}
String templateFile = annualReportPath + "\xx.ftl";
String exportFile = annualReportPath + "\xx.doc";
try {
iWordExportService.getInstance().createDocFile(templateFile, dataMap, exportFile, 1);
iWordExportService.downloadFile(exportFile, "xx.doc", request, response);
} catch (Exception e) {
e.printStackTrace();
