在下面的 Java 代码中，我通过转换存储在字符串中的生成的 xml 数据来创建一个 *.html 报告，
combinedDDIString
...针对 XSLT 文件，
reportXSLT
...并将结果写入物理文件，
tmpReportHTML.
然后代码将文件读回字符串以在其他方法中使用。我想避免将结果写入文件，只需将结果直接转换为字符串即可。
有什么办法可以直接将转换结果写入字符串，并避免将结果写入物理文件？
String reportString = null;
FileInputStream stream = null;
ByteArrayOutputStream reportBAOS = new ByteArrayOutputStream();
try {
System.setProperty("javax.xml.transform.TransformerFactory", "net.sf.saxon.TransformerFactoryImpl");
transformerFactory = TransformerFactory.newInstance();
transformer = transformerFactory.newTransformer(new StreamSource(reportXSLT));
transformer.setOutputProperty(OutputKeys.ENCODING, "US-ASCII");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
/*
* Create a new report file time-stamped for uniqueness, to avoid concurrency issues
*/
DateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmmss");
Date date = new Date();
File tmpReportHTML = new File(reportHTML + dateFormat.format(date) + ".html");
/*
* Perform the transform to get the report
*/
FileOutputStream reportFOS = new FileOutputStream(tmpReportHTML);
OutputStreamWriter osw = new OutputStreamWriter(reportFOS, "US-ASCII");//(reportBAOS), "US-ASCII");
transformer.transform(new StreamSource(new StringReader(combinedDDIString)), new StreamResult(osw));
osw.close();
/*
* Get the report as a string from the temp report file
*/
//FileInputStream stream = new FileInputStream(new File(REPORT_OUTPUT));
stream = new FileInputStream(tmpReportHTML); //(new File(reportXML));
FileChannel fc = stream.getChannel();
MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
reportString = Charset.defaultCharset().decode(bb).toString();
/*
* Delete the temp report file
*/
tmpReportHTML.delete();
} catch (TransformerConfigurationException e) {
e.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
}
finally {
stream.close();
在此先感谢您的帮助。
