java - Apache POI Zip 文件已关闭

Question

我正在创建一个 Web API(使用 Spring Boot 2.1.1.RELEASE)，它接受输入 dotx 文件和参数(如姓名或电话)，在输出中创建带有更改的 docx 文件(我是使用 Apache POI 4.0.1)。

步骤:

1- 获取输入 dotx 和 params。

2- 将 dotx 转换为 docx。

3-添加参数到docx文件并发送。

Controller :

@PostMapping("/addcontent")
public ResponseEntity<ByteArrayResource> convertion(@RequestParam(value = "file",required = false) MultipartFile file,@RequestParam(value="input",required = false) String para) throws  InvalidFormatException, IOException{
    Map<String,String> m = new HashMap<String,String>();
    m.put("namur",para);
    String document = "D:/"+file.getContentType().substring(0, file.getOriginalFilename().length() - 4)+"docx";
    ChangeDot.addContentTodot(m, file.getOriginalFilename(),document );

    FileSystemResource out = new FileSystemResource(document);

     return ResponseEntity
                .ok()
                .contentLength(out.contentLength())
                .contentType(
                        MediaType.parseMediaType("application/vnd.openxmlformats-officedocument.wordprocessingml.document"))
                .body(new ByteArrayResource(IOUtils.toByteArray(out.getInputStream())));
}

}

ChangeDot 类(这个类完成所有的功能) Controller 只需调用它:

public class ChangeDot {

private ChangeDot() {
}

public  static void addContentTodot(Map<String, String> m , String dot , String document ) throws FileNotFoundException, IOException, InvalidFormatException {

    //convert Dotx to Docx
    XWPFDocument doc = new XWPFDocument(OPCPackage.open(dot)) ;
    doc.getPackage().replaceContentType(
               "application/vnd.openxmlformats-officedocument.wordprocessingml.template.main+xml",
               "application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml");

    Iterator<Entry<String, String>> it = m.entrySet().iterator();
    while (it.hasNext()) {
        Entry<String, String> pair = it.next();
         String key=(String) pair.getKey();
         String val =(String) pair.getValue();
         for (XWPFParagraph p : doc.getParagraphs()) {
             List<XWPFRun> runs = p.getRuns();
             if (runs != null) {
                 for (XWPFRun r : runs) {
                     String text = r.getText(0);
                     if (text != null ) {

                         text = text.replace(key, val);// your content
                         r.setText(text, 0);

                     }
                 }
             }
        }
        it.remove(); // avoids a ConcurrentModificationException

    }
    doc.write(new FileOutputStream(document));
    doc.close();

}

}

问题是:当我尝试使用 PostMan 发送请求时，出现此错误:

请，如果有任何建议，请不要犹豫。

谢谢!

Answer 1

看起来您正在将 MultipartFile.getOriginalFilename() 值(这是客户端系统上的文件的名称)传递给 OPCPackage.open()方法，它需要服务器上的文件名。

您应该这样做(file 是 MultipartFile 实例):

InputStream inputStream = file.getInputStream();
XWPFDocument doc = new XWPFDocument(OPCPackage.open(inputStream));
