解决dom4j解析xml文件时访问DTD文件问题

主要代码是：

Reading codes:

        SAXReader saxReader = new SAXReader(false);

        NullEntityResolver resolver = new NullEntityResolver();

        saxReader.setEntityResolver(resolver);

        Document document = saxReader.read(xmlFileName);

EntityResolver codes:

class NullEntityResolver implements EntityResolver {

    static String emptyDtd = "";

    static ByteArrayInputStream byteIs = new ByteArrayInputStream(emptyDtd.getBytes());

    public InputSource resolveEntity(String publicId, String systemId) throws SAXException, IOException {

        return new InputSource(byteIs);

    }

}
