java - SAXReader 返回文件过早结束

Question

我有这段代码，它从通过 HttpServletRequest 请求传递的 URL 获取 XML 文件。我检查了非空/空的请求和 inStream 的值。但我收到错误“文档第 -1 行错误：文件过早结束。嵌套异常：文件过早结束。” request 和 inStream 值分别显示为 org.apache.catalina.connector.RequestFacade@34a7fc0 org.apache.catalina.connector.CoyoteInputStream@100917f0。以下是代码

private void processRequest(HttpServletRequest request,
                HttpServletResponse response, VariablesSecureApp vars) {
    // TODO Auto-generated method stub
    try {
        System.out.println(request);
        InputStream inStream = request.getInputStream();
        System.out.println(inStream);
        SAXReader sax = new SAXReader();
        Document doc = sax.read(inStream);
        System.out.println(doc);
        Element rootElement = (Element) doc.getRootElement();
        if (!rootElement.getName().equals("ob")){
            throw new  OBException("The root element of the xml document should be: Ob but it is " + rootElement.getName());
        }
        //createSalesOrder(doc,response,request);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (DocumentException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

这可能是因为您正在阅读的 XML 文件格式不正确。

这可能意味着缺少结束标记，或者即使未找到文件结尾字符。
