我正在尝试使用PDFBox 2.0.1版将徽标添加到我的PDF文件中。我有以下代码:

public class PDFService {

    public void createPdf() {
        // Create a document and add a page to it
        PDDocument document = new PDDocument();

        PDPage page = new PDPage();

        document.addPage(page);

        // Create a new font object selecting one of the PDF base fonts
        PDFont font = PDType1Font.HELVETICA_BOLD;

        ServletContext servletContext = (ServletContext) FacesContext
                .getCurrentInstance().getExternalContext().getContext();

        try {

            PDImageXObject pdImage = PDImageXObject.createFromFile(
                    servletContext.getRealPath("/resources/images/logo.png"),
                    document);

            PDPageContentStream contentStream = new PDPageContentStream(
                    document, page);

            contentStream.drawImage(pdImage, 20, 20);

            contentStream.beginText();
            contentStream.setFont(font, 12);
            contentStream.endText();

            // Make sure that the content stream is closed:
            contentStream.close();

            // Save the results and ensure that the document is properly closed:
            document.save("Hello World.pdf");
            document.close();

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}


我收到错误javax.imageio.IIOException:无法读取输入文件!在行中

PDImageXObject pdImage = PDImageXObject.createFromFile(
                    servletContext.getRealPath("/resources/images/logo.png"),
                    document);


servletContext.getRealPath返回的路径为C:\Users\erickpezoa\Desktop\Multivision\Materials\apps\eclipse Kepler\eclipse\Projects\.metadata\.plugins\org.eclipse.core.resources\Servicios_Exequiales\build\weboutput\resources\images\logo.png

我在这里做错了什么?

最佳答案

如果您使用的是Maven,并且images文件夹位于Eclipse中的src / main / resources下,则可以尝试:

PDImageXObject pdImage = PDImageXObject.createFromFile(
                PDFService.class.getResource("/images/logo.png").getPath(),
                document);


仅当/resources/images/logo.png下有另一个名为src/main/resources的文件夹时,才需要resources作为路径。或不使用Maven,并且您的输出文件夹包含:/ resources / images。在这种情况下:

PDImageXObject pdImage = PDImageXObject.createFromFile(
                PDFService.class.getResource("/resources/images/logo.png").getPath(),
                document);


希望能帮助到你。
