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);
}
}
