无法在java中获取绝对路径的相对路径

我给出了属性文件的图像路径，并在我的pdfGenerating类中获得了图像类的路径。比如：

properties.load(DownloadPdf.class.getResourceAsStream("/resource.properties"));
System.out.println("--properties----"+properties);
System.out.println("-path-"+properties.getProperty("logoPath"));
//String path = properties.getProperty("logoPath");
//URL uri = Paths.get(path).toUri().toURL();
System.out.println("---path-"+properties.getProperty("logoPath"));
Image image = Image.getInstance(properties.getProperty("logoPath"));

我的登录路径如下：

path----------------C:/Users/Home/Documents/workspace-gofindo/.metadata/.plugins/org.eclipse.wst.server.core/.....

但我正在把路弄进去

Image.getInstance(properties.getProperty("logopath"));

像

我已尝试使用replace和replaceAll方法将“\”转换为“/” 再次将图像类转换为“\”。

如何将我在属性文件中指定的绝对路径精确地转换为Image.getInstance方法

我重新修改了读取文件路径的方式，如下所示

        // Load path of the Image from Properties file
        Properties properties = new Properties();
        properties.load(this.getClass().getResourceAsStream(
                "/resource.properties"));
        // To get the Path of the Context
        String contextPath = request.getContextPath();
        String split_path[] = contextPath.split("/");
        contextPath = request.getRealPath(split_path[0]);
        Image image = Image.getInstance(contextPath
                    + properties.getProperty("logoPath"));
        image.scaleAbsolute(120f, 60f);// image width,height

您知道\是windows上的正确字符，对吗？/也支持作为bonusAnd\vs/与绝对路径和相对路径无关。这是哪个图像类？此处图像类对象采用的路径类似于c:\Users\Home\。。。。并表示找不到指定路径并引发FileNotFoundException。当我将其硬编码为c:/Users/Home时。。。我正在将指定路径中的图像导入pdf文档。Im使用com.itextpdf.text.Image class@Ravi Thapliyal

        // Load path of the Image from Properties file
        Properties properties = new Properties();
        properties.load(this.getClass().getResourceAsStream(
                "/resource.properties"));
        // To get the Path of the Context
        String contextPath = request.getContextPath();
        String split_path[] = contextPath.split("/");
        contextPath = request.getRealPath(split_path[0]);
        Image image = Image.getInstance(contextPath
                    + properties.getProperty("logoPath"));
        image.scaleAbsolute(120f, 60f);// image width,height
