問題描述

我有一些使用JasperReports庫導出的報告。 除了excel文件（xls）都很好。 例如，當我嘗試將包含751行的精確報告導出為ex​​cel文件時，沒有問題，並且可以正確下載excel文件，但是當它超過800行時，它將顯示一些不相關的字符。 上面提到的行大小僅適用於此報告，而其他報告的行數限制為不同的數字。 在將庫從版本2.3升級到6.1.0之前，不存在此問題，現在我嘗試了6.2.2。

這是我創建Excel文件的方式： 

    JasperPrint jasperPrint;
    try {
        jasperPrint = getReportPrint(request, baseForm, "excel");
    } catch (ReportNoDataException e) {
        return handleNoData(mapping, request, e);
    }

    try {
        JRXlsExporter jrXlsExporter = new JRXlsExporter();
        try {
            jrXlsExporter.setExporterInput(new SimpleExporterInput(jasperPrint));
            jrXlsExporter.setExporterOutput(new SimpleOutputStreamExporterOutput(response.getOutputStream()));

            SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration();
            configuration.setIgnoreCellBorder(true);
            configuration.setWrapText(true);
            configuration.setWhitePageBackground(false);
            configuration.setRemoveEmptySpaceBetweenColumns(true);
            configuration.setRemoveEmptySpaceBetweenRows(true);
            configuration.setAutoFitPageHeight(true);
            configuration.setDetectCellType(true);
            configuration.setSheetDirection(RunDirectionEnum.RTL);

            jrXlsExporter.setConfiguration(configuration);
            jrXlsExporter.exportReport();
        } catch (IOException e) {
            log.error("IOException occured" + e);
            e.printStackTrace();
        } catch (JRException e) {
            log.error("JRException occured while exporting for xls format", e);
            e.printStackTrace();
        }
    } catch (Exception e) {
        throw e;
    }
    String filename="report";
    response.setHeader("Content-disposition","attachment; filename=\""+filename+".xls\"");
    putSearchForm(request, baseForm);
    return null;

這是報告代碼：

您正在查看的輸出是Excel輸出。 如果您在文本編輯器中將其打開，這就是Excel文件的樣子（我隨機抽取了XLS文件，並在Notepad ++中將其打開）：

在此處輸入圖片說明

這意味着您的響應不是將內容作為Excel文件提供，而是作為直接下載提供，直接在瀏覽器中顯示。

嘗試在響應中添加其他參數（ 從此處開始並設置為適合Java），以便更加明確： 

response.setHeader("Content-Type:   application/vnd.ms-excel; charset=utf-8");
response.setHeader("Expires: 0");
response.setHeader("Cache-Control: must-revalidate, post-check=0, pre-check=0");
response.setHeader("Cache-Control: private");

編輯

如果較大的文件發生這種情況，請看一下描述相同問題的答案 。 一般來說，應該先發送響應頭，然后再生成報告文件。

簡而言之：您應該首先將所有內容首先寫入標頭（我懷疑您確實對response更高的要求），然后嘗試生成文件。 這樣瀏覽器就會得到結果，看到一個應用程序文件將要下載。 否則，據我所知， response頭是在文件生成后設置的-對於瀏覽器來說，等待Content-Type可能太長了。
