java.util.zip.ZipException：沒有當前 ZIP 條目

Question

我正在嘗試創建一個 csv 文件並將其壓縮。 我看到的問題是它沒有我想要擁有的列，我只看到 164 列帶有以下字符串（存在於字符串數組中）。 看起來此異常的原因是大小（即 csv 中列名的字節大小計數）超過 8192 個字節。 如何增加此限制或任何其他解決方案？

                    new OutputStreamWriter(zos),
                    CSVFormat.EXCEL.withHeader(csvHeaderElements)
                    //CSVFormat.DEFAULT.withHeader(csvHeaderElements)
            );
        } catch (IOException e)
        {
            e.printStackTrace();
        }


    }
}

Answer 1

您不能僅通過將 CSV 文件的內容復制到其中來創建 zip，您需要先創建一個 zip 條目。 所以代碼應該是這樣的：

String[] csvHeaderElements = { // some headers separated with semicolon
        };
try (ZipOutputStream zos = new ZipOutputStream(new FileOutputStream("C:/Users/TestUser/Downloads/test.zip"))) {
    // create zip entry
    ZipEntry entry = new ZipEntry("test.csv");
    zos.putNextEntry(entry);

    CSVPrinter csvPrinter = new CSVPrinter(new OutputStreamWriter(zos), CSVFormat.EXCEL.builder().setHeader(csvHeaderElements).build());
    // some action with csvPrinter
    // ...

    // close entry
    zos.closeEntry();
}

Answer 2

ZIP 流需要一個條目 - 這將在 ZIP 內容中設置文件名。 對資源使用 try 以確保正確關閉 ZIP 輸出流。 此示例定義名為“somename.xyz”的條目中的內容：

try(ZipOutputStream zos = new ZipOutputStream(out)) {
    zos.putNextEntry(new ZipEntry("somename.xyz"));

    OutputStreamWriter wr = new OutputStreamWriter(zos);
    CSVPrinter csvPrinter = new CSVPrinter(wr,
      CSVFormat.EXCEL.withHeader(csvHeaderElements)
    );
    // ...
    csvPrinter.flush();
}

請注意，OutputStreamWriter 中使用的流編碼器的緩沖區大小為 8192，因此您在 8192 處剪切 CSV 列的次要問題可能是您缺少csvPrinter.flush(); 在處理完 CSV 打印之后。

或者您可能對設置更簡單的 GZIP 流感到困惑，只需將ZipOutputStream更改為GZIPOutputStream ：

try(GZIPOutputStream zos = new GZIPOutputStream(out)) {
    OutputStreamWriter wr = new OutputStreamWriter(zos);
    CSVPrinter csvPrinter = new CSVPrinter(wr,
      CSVFormat.EXCEL.withHeader(csvHeaderElements)
    );
    // ...
    csvPrinter.flush();
}
