Java如何根据word模板导出数据

pom.XML文件导入依赖 

<dependency>
    <groupId>cn.afterturn</groupId>
    <artifactId>easypoi-spring-boot-starter</artifactId>
    <version>4.4.0</version>
</dependency>

以下为导出代码：

    */
    public static void easyPoiExport(String templatePath, String tempDir, String filename, Map<String, Object> data, HttpServletRequest request, HttpServletResponse response) {
    if (!tempDir.endsWith("/")) {
        tempDir = tempDir + File.separator;
    }
 
    File file = new File(tempDir);
    if (!file.exists()) {
        file.mkdirs();
    }
 
    try {
        String userAgent = request.getHeader("user-agent").toLowerCase();
        if (userAgent.contains("msie") || userAgent.contains("like gecko")) {
            filename = URLEncoder.encode(filename, "UTF-8");
        } else {
            filename = new String(filename.getBytes("utf-8"), "ISO-8859-1");
        }
        //防止文件过大，报错：java.io.IOException: Zip bomb detected! The file would exceed the max
php        ZipSecureFile.setMinInflateRatio(-1.0d);
        //开始导出文件操作
        XWPFDocument document = WordExportUtil.exportWord07(templatePath, data);
        String tempPath = tempDir + filename;
        FileOutputStream out = new FileOutputStream(tempPath);
        document.write(out);
 
        // 设置响应规则
        response.setContentType("application/force-download");
        response.addHeader("Content-Disposition", "attachment;filename=" + filename);
        OutputStream stream = response.getOutputStream();
        document.write(stream);
        stream.close();
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        deleteTempFile(tempDir, filename);
    }
 }
 
    /**
    * 删除临时生成的文件
    */
    public static void deleteTempFile(String filePath, String fileName) {
        File file = new File(filePath + fileName);
        File f = new File(filePath);
        file.delete();
        f.delete();
 }
}

Word模板数据效果：

方法补充

java实现根据word模板导出数据

模板文件：

模板描述：{{?govinspectItemVOList}} 为循环遍历的数据实体

代码块：

//生成文件所在路径
String dirName = System.getProperty("user.dir") + File.separator + "file";
//模板文件存放地址
String templateFileName = dirName + File.separator + "质量安全巡查检查报告.docx";
//生成的临时文件
String fileName = "质量安全巡查检查报告" + System.currentTimeMillis() + ".docx";
WordUtils.fill(response, dirName, fileName, templateFileName, exportProjectReportVO);
