transformer.transform（..正在抛出IO异常/找不到文件异常

Question

DOMSource source = new DOMSource(document);
                ewFile = barcoUtil.getEwFile(Ew_Thread.ewLogger);
                StreamResult result = new StreamResult(ewFile);
                System.out.println("Ok I have came here--->"+ewFile.getAbsolutePath());
                transformer.transform(source, result);

它生成FileNotFoundException

Ok I have came here--->F:\Barco\employwise-barco files\EW_2015-05-05 14-35-55.txt
javax.xml.transform.TransformerException: java.io.FileNotFoundException: F:\Barco\employwise-barco%20files\EW_2015-05-05%2014-35-55.txt (The system cannot find the path specified)
    at org.apache.xalan.transformer.TransformerIdentityImpl.createResultContentHandler(TransformerIdentityImpl.java:297)

但文件已经存在。

我唯一怀疑的是，因为抛出异常的url包含％20而不是空格，可能是windows无法识别路径。

还有什么原因？

Answer 1

解决了问题昨天，问题是包含％20的路径为空格。我改变了

StreamResult result = new StreamResult（ewFile）; 到StreamResult result = new StreamResult(ewFile.getPath());

并且有效。
