PDF导出中的错误

Question

这是我的代码片段-

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();

//帮助方法

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;
    }

我不明白实际的问题是什么。我有两种数据‘活动’/‘不活跃’，因此我增加了三值运算符来改变不活动数据的背景色。对于活动数据，pdf导出工作非常好。但对于非活动数据，以下是例外情况。

此外，java进程占用了CPU使用率的95%。服务器变得非常慢。我必须手动停止java进程并重新启动服务器。

Answer 1

问题解决了-

由于现有体系结构的依赖关系，我无法更新jar。

但真正的问题是跨行。活动/非活动部件的行距不同。在改变了这种逻辑之后，问题得到了解决。
