Answer 2

解决方案:
后面找到了其中的原因:
是网络的问题.因为DOCTYPE的连接不同造成的.
使用了saxreader解析器的时候,会自动解析DOCTYPE里面的内容.如果连接不上网络,则会报连接超时的异常.
所以为了,不然解析DOCTYPE,则reader.setFeature(不加载dtd文件,false); 就不会去解析DOCTYPE了.
即可.SAXReader reader = new  SAXReader();
reader.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);

Answer 3

static public Document getRequestDocument(HttpServletRequest request) throws IOException, DocumentException {
ServletInputStream is = request.getInputStream();
SAXReader saxReader = FastSAXReader.getReader();
Document doc = saxReader.read(new InputSource(is));
FastSAXReader.release(saxReader);
System.out.println(doc.asXML());
return doc;
}
这是代码，麻烦帮我看看有问题没？
