我正在创建用于在两种语言之间翻译单词的Web服务。单词在位于项目文件夹根目录的xml文档(dictionary.xml)中定义。服务可以在绝对路径下正常运行,但是在使用相对路径进行测试时,会出现FileNotFound异常。
我尝试只写(“字典”),并且在我正在解析xml文件的项目中起作用。
这是方法:
public String translate(String word, String lang1, String lang2) throws XPathExpressionException, FileNotFoundException {
XPathFactory factory = XPathFactory.newInstance();
XPath path = factory.newXPath();
String expression = "";
if (lang1.equals("english")) {
expression = "dictionary/word/english";
} else if (lang1.equals("spanish")) {
expression = "dictionary/word/spanish";
}
XPathExpression xPathExpression = path.compile(expression);
File xmlDocument = new File("D:\\JavaLearning\\AssignmentWebService\\Translator\\dictionary.xml");
InputSource inputSource = new InputSource(new FileInputStream(xmlDocument));
Object result = xPathExpression.evaluate(inputSource, XPathConstants.NODESET);
NodeList nodeList = (NodeList) result;
String translatedWord = "";
for (int i = 0; i < nodeList.getLength(); i++) {
if (lang1.equals("english") && word.equals(nodeList.item(i).getTextContent())) {
translatedWord = nodeList.item(i).getNextSibling().getNextSibling().getTextContent();
} else if (lang1.equals("spanish") && word.equals(nodeList.item(i).getTextContent())) {
translatedWord = nodeList.item(i).getPreviousSibling().getPreviousSibling().getTextContent();
}
}
if (translatedWord.equals("")) {
translatedWord = "Word \"" + word + "\" doesn't exist in our database!";
}
return translatedWord;
}
错误:由以下原因引起:service.FileNotFoundException_Exception: dictionary.xml(系统找不到指定的文件),位于
