dom4j读取xml的问题

Question

dom4j可以解析任何的xml文件。你的超时一定是由其他原因引起的。比如，你读取访问xml的方式等等。由于看不到你的读取xml文件的代码，所以不知道具体原因

读这个就报错

Answer 2

我说的代码不是指的这个，而是指的你读取xml文件的java代码。解析xml之前，先要读取这个xml文件。你是如何读取的？把这个代码贴出来

Answer 3

    public static String getResultColumn (String resultName, String property) {
        String[][] returnArr = null;
        SAXReader reader = new SAXReader ();
        File configFile = new File (ConstantUtils.resultPath);
        Document document = null;
        try {
            document = reader.read (configFile);
            // System.out.println (document.asXML ());
        }
        catch (Exception ex) {
            ex.printStackTrace ();
        }
        // System.out.println
        // (document.selectSingleNode("/resultMap[@id='"+resultName+"']").asXML
        // ());
        List list = document.selectSingleNode (
            "/resultMap[@id='" + resultName + "']").selectNodes ("result");
        Iterator iter = list.iterator ();
        String returnStr = null;
        while (iter.hasNext ()) {
            Element element = (Element) iter.next ();
            if (element.attributeValue ("property").equals (property)) {
                returnStr = element.attributeValue ("column");
                break;
            }        }
        return returnStr;
    }

Answer 4

超时应该是因为解析dtd，然后你的机器连网络上的dtd文件的时候出的
xml文件里的
<!DOCTYPE sqlMap
PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-2.dtd">
删掉试试
