我在为在流中编辑 XML 文件的问题实施解决方案时遇到了麻烦。我得到一个 MalFormedUrlException: no protocol。XML 文件编码为 UTF-8,没有文档类型,但格式正确。我很困惑为什么会这样。
这是有问题的代码(byteArray
有xml,UpdatingXmlReader
是我的班级):
XMLReader reader =
new UpdatingXmlReader(SAXParserFactory.newInstance().newSAXParser());
Transformer xform = TransformerFactory.newInstance().newTransformer();
InputSource inputSource =
new InputSource(new ByteArrayInputStream(byteArray));
StreamResult streamResult =
new StreamResult(response.getOutputStream());
SAXSource saxSource = new SAXSource(reader, inputSource);
xform.transform(saxSource, streamResult);
在我的测试中如何调用它:
File file = new File("c:/test.xml");
InputStream input = new FileInputStream(file);
byte[] b = IOUtils.toByteArray(input);
// in production the byte array will come from the database
service.method(b, httpServletResponse ,httpServletRequest)
这是堆栈跟踪:
