最近公司来了个项目，需要把数据库数据查询，进行组装然后导出为doc文档。查阅了下网上资料，决定使用freeMaker来开发。

首先打开word，编辑文档。然后将文档另存为后缀为ftl的文件。

 贴上代码：

@ApiImplicitParam(name = "exportReportWord", value = "检查报告导出", dataType = "ChkReportPageQuery")
@ApiOperation(value = "检查报告导出")
@PostMapping("/exportReportWord")
public void exportReportWord(HttpServletRequest request, HttpServletResponse response, @RequestBody ChkReportPageQuery pageQuery) throws IOException {
  // 告诉浏览器用什么软件可以打开此文件
  response.setHeader("content-Type", "application/msword");
  // 下载文件的默认名称
  response.setHeader("Content-Disposition", "attachment;filename=xx.doc");
  String path = new File("").getAbsolutePath();
  Map dataMap = new HashMap<>();
  dataMap.put("userName","陈聪");
  dataMap.put("frame","SpringCloud");
  dataMap.put("tools","freeMarker");
  Configuration configuration = new Configuration();
  configuration.setDefaultEncoding("UTF-8");
  //项目地址
  configuration.setClassForTemplateLoading(this.getClass(),"/template");
  Template template = null;
  try{
    template = configuration.getTemplate("/导出doc测试.ftl");
  }catch (IOException e){
    e.printStackTrace();
  }
  //输出文档路径和地址
  File outFile = new File(path+"/export/wordExport.doc");
  Writer out = null;
  FileOutputStream fileOutputStream = null;
  try{
    fileOutputStream = new FileOutputStream(outFile);
    OutputStreamWriter outputStreamWriter = new OutputStreamWriter(fileOutputStream,"UTF-8");
    out = new BufferedWriter(outputStreamWriter);
  }catch (FileNotFoundException fileExp){
    fileExp.printStackTrace();
  }
  try{
    template.process(dataMap,out);
    out.close();
    fileOutputStream.close();
    //下载文件
    DownLoadUtil.downLoadFile(path+"/export/wordExport.doc",response);
  }catch (TemplateException tExp){
    tExp.printStackTrace();
  }
}

public class DownLoadUtil {

    static Logger logger = LoggerFactory.getLogger(DownLoadUtil.class);

    public static void downLoadFile(String fullPath, HttpServletResponse response) {
        logger.info("【downLoadFile:fullPath】：==>" + fullPath);

        InputStream inputStream = null;
        OutputStream outputStream = null;

        try {
            //创建文件
            File file = new File(fullPath);
            String fileName = file.getName();

            //读文件流
            inputStream = new BufferedInputStream(new FileInputStream(file));
            byte[] buffer = new byte[inputStream.available()];
            inputStream.read(buffer);

            //清空响应
            response.reset();
            response.setCharacterEncoding("UTF-8");
            response.setContentType("application/octet-stream; charset=utf-8");
            // response.setContentType("application/msword");
            response.setHeader("Content-Disposition","attachment; filename=" + new String(fileName.getBytes(), "ISO8859-1"));
            response.setHeader("Content-Length", "" + file.length());

            //写文件流
            outputStream = new BufferedOutputStream(response.getOutputStream());
            outputStream.write(buffer);
            outputStream.flush();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (outputStream != null) {
                    outputStream.close();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
            try {
                if (inputStream != null) {
                    inputStream.close();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    }

}



如果有循环的数据需要在模板中定义list，然后将list数据放进dataMap。如下：

 至此SpringCloud使用freeMarker导出doc文件完成。

 导出效果，不循环：

循环效果：
