Question

当我使用main方法在单个java文件中运行它时，代码工作正常，但我的问题是当我将它放在我的spring mvc项目中然后它给我在转换时找不到错误文件。我无法理解究竟是什么问题，相同的代码在一个单独的类中运行但在我的项目中没有请一些身体帮助我。感谢...

 File xmlFile = new File("d:\\file1.xml");
     Reader fileReader = new FileReader(xmlFile);
        BufferedReader bufReader = new BufferedReader(fileReader);

        StringBuilder sb = new StringBuilder();
        String line = bufReader.readLine();
        while( line != null){
            sb.append(line).append("\n");
            line = bufReader.readLine();
        }
        String xml = sb.toString();

    //String xml = "<users><user><name>user1</name></user></users>";
    XMLReader xr = new XMLFilterImpl(XMLReaderFactory.createXMLReader()) {
        private String tagName = "";

        @Override
        public void startElement(String uri, String localName, String qName, Attributes atts) throws SAXException {
            tagName = qName;
            super.startElement(uri, localName, qName, atts);
        }

        public void endElement(String uri, String localName, String qName) throws SAXException {
            tagName = "";
            super.endElement(uri, localName, qName);
        }

        @Override
        public void characters(char[] ch, int start, int length) throws SAXException {
            if (tagName.equals("author")) {
                ch = uploadXmlBean.getAuthor().toCharArray();
                start = 0;
                length = ch.length;
            }
            if (tagName.equals("currency")) {
                ch = uploadXmlBean.getCurrency().toCharArray();
                start = 0;
                length = ch.length;
            }

            if (tagName.equals("name")) {
                ch = uploadXmlBean.getName().toCharArray();
                start = 0;
                length = ch.length;
            }

            if (tagName.equals("logicalHeading")) {
                ch = uploadXmlBean.getLogicalHeading().toCharArray();
                start = 0;
                length = ch.length;
            }

            super.characters(ch, start, length);
        }
    };
    Source src = new SAXSource(xr, new InputSource(new StringReader(xml)));

    Result res = new StreamResult(xmlFile);
    TransformerFactory.newInstance().newTransformer().transform(src, res);

在我的项目类中实现的代码是

@RequestMapping(value = "/xmlEditor", method = RequestMethod.POST)
public String xmlEditor(@ModelAttribute("UploadXmlBean") final UploadXmlBean uploadXmlBean) throws Exception {
    System.out.println("xmlEditor");
    employeeService.addXml(uploadXmlBean);
    //xmlAppService.addXml(uploadXmlBean);

        while( line != null){
            sb.append(line).append("\n");

Answer 1

请尝试以下更改并尝试一次：

File xmlFile = new File("d:\\file1.xml").getAbsoluteFile()

使用SAX Parser编辑xml内容
