Apache POI Zip файл закрыт

0 голосов
/ 07 марта 2019

Я создаю веб-API (с Spring Boot 2.1.1.RELEASE), который принимает на вход файл dotx и параметры (например, имя или телефон), на выходе он создает файл docx с изменениями (я используя Apache POI 4.0.1).

шаги:

1- взять точку ввода и параметры.

2 - конвертировать dotx в docx.

3 - добавить параметры в файл docx и отправить его.

Контроллер: 

@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())));
}

}

класс ChangeDot (этот класс выполняет все функции), контроллер просто вызывает его: 

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();

}

}

Проблема: при попытке отправить запрос с помощью PostMan я получаю эту ошибку:

Пожалуйста, если есть какие-либо предложения, не стесняйтесь.

Спасибо!

Похоже, вы передаете значение MultipartFile.getOriginalFilename() (которое является именем файла в клиентской системе) методу OPCPackage.open(), который ожидает имя файла на сервере.

Youследует сделать что-то вроде этого (file - это экземпляр MultipartFile): 

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

Попробуйте это: 

@PostMapping("/addcontent")
public ResponseEntity<FileSystemResource> 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(out);
}
