錯誤在PDF導出

Question

這裏是我的代碼snippet-

getResponse().setContentType(NAPSConstants.PDF_CONTENT_TYPE); 
getResponse().setHeader(NAPSConstants.PDF_CONTENT_DISP, NAPSConstants.PDF_ATTACHMENT_FILE+getText("rcmid.details")+NAPSConstants.PDF_EXTN); 
//Set the Page Size 
Document document = new Document(PageSize.A3, 40, 40, 40, 40); 

    PdfPTable table = new PdfPTable(rcmDetailsCols.length); 
    for(RCMIDPartsDetailsDTO part : rcmidDTO.getPartsDetailsDTO()){ 
      table.addCell(part.getPartStatus().equals(NAPSConstants.Active) ? 
        PDFHelper.dataCell(part.getPlantName(), PDFHelper.FONT_DATA) : 
PDFHelper.coloredDataCell(part.getPlantName(), PDFHelper.FONT_DATA)); 
table.addCell(part.getPartStatus().equals(NAPSConstants.Active) ? 
          PDFHelper.dataCell(part.getOemSupplierId(), PDFHelper.FONT_DATA):PDFHelper.coloredDataCell(part.getOemSupplierId(), PDFHelper.FONT_DATA)); 
table.addCell(PDFHelper.dataCellWithRowSpan(rcmidDTO.getPackSupplierId(), PDFHelper.FONT_DATA, rcmidDTO.getActiveRowSpan()+rcmidDTO.getPartsList.size())); 

       } 
       document.add(table); 

    document.close(); 

//輔助方法，

public static PdfPCell dataCell(String cellText, Integer fontSize) 
    { 
     PdfPCell cell = new PdfPCell(); 
     if(cellText==null || cellText.compareTo("null")==0 || NAPSConstants.EMPTY_STRING.equals(cellText) || 
       cellText.equals(NAPSConstants.MINUS_ONE)){ 
      //cellText = NAPSConstants.TEXT_NA; 
      cellText = NAPSConstants.EMPTY_STRING; 
     } 
     cell.setPhrase(new Phrase(cellText, new Font(Font.NORMAL, fontSize))); 
     cell.setHorizontalAlignment(Element.ALIGN_CENTER); 
     return cell; 
    } 
public static PdfPCell coloredDataCell(String cellText, Integer fontSize) 
    { 
     PdfPCell cell = new PdfPCell(); 
     if(cellText==null || cellText.compareTo("null")==0 || NAPSConstants.EMPTY_STRING.equals(cellText) || 
       cellText.equals(NAPSConstants.MINUS_ONE)){ 
      //cellText = NAPSConstants.TEXT_NA; 
      cellText = NAPSConstants.EMPTY_STRING; 
     } 

     cell.setPhrase(new Phrase(cellText, new Font(Font.NORMAL, fontSize,0, new Color(255,0,0)))); 
     cell.setHorizontalAlignment(Element.ALIGN_CENTER); 

     cell.setBackgroundColor(new Color(200, 200, 200)); 
     return cell; 
    } 

public static PdfPCell dataCellWithRowSpan(String cellText, Integer fontSize, int rowspan) 
    { 
     PdfPCell cell = new PdfPCell(); 
     cell.setRowspan(rowspan); 
     cell.setHorizontalAlignment(Element.ALIGN_CENTER); 
     cell.setVerticalAlignment(Element.ALIGN_MIDDLE); 
     if(cellText==null || cellText.compareTo("null")==0){ 
      //cellText = NAPSConstants.TEXT_NA; 
      cellText = NAPSConstants.EMPTY_STRING; 
     } 

     cell.setPhrase(new Phrase(cellText, new Font(Font.NORMAL, fontSize))); 
     return cell; 
    } 

我無法瞭解實際的問題是什麼。 我有兩種數據'有效'/'無效'，因此我添加了三元運算符來更改非活動數據的背景顏色。 PDF導出對於活動數據非常適用。但對於非活動數據，以下情況是例外。

此外，java進程佔用CPU使用率高達95％。服務器變得非常慢。我必須手動停止java進程並重新啓動服務器。

問題solved-

我無法更新，因爲現有的架構的依賴關係的罐子。

但真正的問題是與rowspan。 活動/非活動部件的行距不同。 更改該邏輯後，問題得以解決。
