用于序列化和反序列化的xstream错误
|
我在Java中使用xStream来从Java库中序列化Java对象，并在客户方反序列化它。
我有几个问题：
如果我这样做：
XStream xstream = new XStream();
xstream.setMode(XStream.ID_REFERENCES);
xstream.autodetectAnnotations(true);
Writer writer = new FileWriter(xmlFile);
writer.write(xstream.toXML(myObject));
writer.close();
XStream xstream = new XStream();
xstream.setMode(XStream.NO_REFERENCES);
xstream.autodetectAnnotations(true);
Writer writer = new FileWriter(xmlFile);
writer.write(xstream.toXML(myObject));
writer.close();
Exception in thread \"main\" com.thoughtworks.xstream.io.StreamException: : only whitespace content allowed before start tag and not . (position: START_DOCUMENT seen .... @1:1)

错误中的句点（。）来自哪里。 fromXML方法需要实际的XML输入，而不是文件名。因此，当它解析您的xml（不是\“ model.xml \”实际的xml）时，就会出现错误。 XStream的站点现在关闭，所以我无法链接到API 使用FileReader / BufferedReader来获取XML的内容。这样的事情应该工作XStream instream = new XStream(); BufferedReader br = new BufferedReader(new FileReader(\"model.xml\")); StringBuffer buff = new StringBuffer(); String line; while((line = br.readLine()) != null){ buff.append(line); } Platform p = (Platform)instream.fromXML(buff.toString());
