我的代码从网络下载 XML 报告并将原始 XML 分配给字符串变量。然后它创建一个 SAXPaser，如下所示：
try {
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setXIncludeAware(true);
spf.setNamespaceAware(true);
spf.setValidating(true); // Not required for JAXB/XInclude
XMLReader xr = (XMLReader) spf.newSAXParser().getXMLReader();
xr.setFeature("http://apache.org/xml/features/disallow-doctype-decl", false); //with true report could not be parsed
xr.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false); // This may not be strictly required as DTDs shouldn't be allowed at all, per previous line.
xr.setFeature("http://xml.org/sax/features/external-general-entities", false);
xr.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
return new SAXSource(xr, new InputSource(new StringReader(output)));
} catch (Exception e) {
e.printStackTrace();
}
然后调用 jaxb 方法来解组 XML，如下所示
jaxbUnmarshaller.unmarshal(saxSource);
这会触发以下异常。在文档中查找类并“ClassLoader：null”
factoryClassName - 提供 javax.xml.parsers.SAXParserFactory 实现的完全限定工厂类名称。
classLoader - 用于加载工厂类的ClassLoader。如果为null，则使用当前线程的上下文classLoader来加载工厂类。
我看到其他人在 SOF 上给出的建议说不要使用“com.sun”包。不幸的是我必须使用 Java 8，具体来说：
openjdk版本“1.8.0_392”
据我所知，异常背后的代码适用于 Oracle Java 8。我将不胜感激任何帮助。谢谢你

XML 的序言中有这个 DTD
