Java 如何禁用预打印xstream xml并仍然添加样式表和prolog？
我可以使用CompactWriter（）删除xml中的预打印（所有换行符/回车符），但是如何保留我的序言和样式表呢 目前我正在使用Writer类使用write方法添加prolog和样式表 下面是我序列化对象的函数Java 如何禁用预打印xstream xml并仍然添加样式表和prolog？,java,xstream,Java,Xstream,我可以使用CompactWriter（）删除xml中的预打印（所有换行符/回车符），但是如何保留我的序言和样式表呢 目前我正在使用Writer类使用write方法添加prolog和样式表 下面是我序列化对象的函数 private void serializeData(DiagData diagData){ fileinfo=new HashMap<String,String>(); XStream xstream = new XStream();

writer.write（常量.样式表）；
toXML（diagData，writer）；

Why does XStream not write an XML declaration?
XStream is designed to write XML snippets, so you can embed its output into
an existing stream or string. You can write the XML declaration yourself into
the Writer before using it to call XStream.toXML(writer).
private static void serializeData(Object diagData) throws Exception {
XStream xstream = new XStream();
xstream.processAnnotations(DiagData.class);
FileOutputStream fileOutputStream = null;
Writer writer = new PrintWriter(new File(your file));
CompactWriter compactWriter = new CompactWriter(writer);
try {
writer.write(your xml prolog);
writer.write(your stylesheet);
xstream.marshal(diagData, compactWriter);
} catch (FileNotFoundException e1) {
} catch (Exception e) {
} finally {
release resources
}
}
如果您查看XStream，它们清楚地表明您必须自己添加XML序言：
