我正在使用Apache FOP 2.1，JAXB和XSLT 1.0生成PDF。该模板有一些嵌入式SVG。 PDF呈现没有任何问题，但FO正在抛出混乱我的日志的错误。XSL-FO：“无法设置基本URL”用于嵌入式svg
设置：
XslProcessor.java
public XslProcessor(File f) {
try {
URIResolverAdapter uriResolverAdapter = new URIResolverAdapter(new UserAgentUriResolver());
FopFactoryBuilder builder = new FopFactoryBuilder(URI.create("/"), uriResolverAdapter);
DefaultConfigurationBuilder defaultConfigurationBuilder = new DefaultConfigurationBuilder();
builder.setConfiguration(defaultConfigurationBuilder.buildFromFile("config/pdf/fop.xconf"));
fopFactory = builder.build();
transformerFactory = TransformerFactory.newInstance();
transformFile = f;
} catch (IOException | SAXException | ConfigurationException e) {
throw new RuntimeException(e);
}
}
public synchronized void process(InputStream is, OutputStream os) {
try {
try(BufferedOutputStream bufferedOut = new BufferedOutputStream(os)) {
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, bufferedOut);
Source xslt = new StreamSource(transformFile);
Transformer transformer = transformerFactory.newTransformer(xslt);
Source source = new StreamSource(is);
Result result = new SAXResult(fop.getDefaultHandler());
transformer.transform(source, result);
}
os.flush();
os.close();
} catch (IOException | FOPException | TransformerException e) {
throw new RuntimeException(e);
}
}
UserAgentUriResolver.java
public class UserAgentUriResolver implements URIResolver {
private static final String USER_AGENT = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.86 Safari/537.36";
private static final String REFERRER = "https://www.google.com";
@Override
public Source resolve(String href, String base) throws TransformerException {
try {
URL url = new URL(href);
URLConnection connection = url.openConnection();
connection.setRequestProperty("User-Agent", USER_AGENT);
connection.setRequestProperty("Referrer", REFERRER);
return new StreamSource(connection.getInputStream());
} catch (IOException e) {
return new StreamSource(new ByteArrayInputStream(new byte[0]));
}
}
}
样本模板：

一旦在模板中每一个SVG ，我得到

不知道这是否是任何解决方案，但这是可怕的代码。您正在创建对象，然后运行测试以查看是否需要任何内容（好）或没有任何内容（违反标准），为什么您的测试不围绕您是否创建流内异物？ –
你能编辑你的问题来包含一个带有所有属性*的结果svg *的例子吗？我只是试着用FOP 2.1来处理从你的代码派生的一个fo文件，它根本没有任何警告，所以我怀疑其他属性有问题。 – lfurini
