使用SAX Parser编辑xml内容

标签： java xml

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);

        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>";

        }
