Question

使用apache fop和springboot生成pdf。 Pdf具有从资源下的/ images文件夹加载的图像。在本地eclipse设置中，此方法工作正常，但一旦打包为jar，就无法解析路径

FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI());
            FOUserAgent foUserAgent = fopFactory.newFOUs

    erAgent();
                ByteArrayOutputStream outputStream = new 
     ByteArrayOutputStream();
                Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, 
     foUserAgent, outputStream);
                TransformerFactory factory = 
     TransformerFactory.newInstance(XSL_LOADER, null);
                 factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
                Transformer transformer = factory.newTransformer(new 
     StreamSource(getClass().getResourceAsStream(XSL_PATH_ROOT)));

解析路径的方法：

private String getImagePath(String icon) {
    if (icon != null) {
        try {
            URL resourceURL = ResourceUtils.getURL(
                    new StringBuilder().append("classpath:images/").append(icon).append(PNG).toString());
            if (ResourceUtils.isJarURL(resourceURL)) {
                URL extractedJarURL = ResourceUtils.extractJarFileURL(resourceURL);
                return extractedJarURL.getPath();
            } else {
                return resourceURL.getPath();
            }
        } catch (FileNotFoundException | MalformedURLException e) {
            e.getStackTrace();
        }
    }
    return null;
}

XSL代码：

<xsl:attribute name="src"><xsl:value-of select="iconName" /></xsl:attribute>

以错误org.apache.fop.apps.FOUserAgent获取错误-找不到图像。 URI：文件：/usr/tomcat/banking-app/banking-app.jar！/ BOOT-INF / classes！/images/ICON1.png。（没有可用的上下文信息）

资源文件夹中的图像未在jar中找到路径
