首先SAXParserFactory来创建一个SAXParserFactory实例
SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();


然后根据SAXParserFactory实例来创建SAXParser,再从SAXParser中得到一个XMLReader的实例，XMLReader是一个接口
XMLReader xmlReader = saxParserFactory.newSAXParser().getXMLReader();

把自己编写的Handler注册到XMLReader中去，一般最重要的就是ContentHandler
 xmlReader.setContentHandler(ContentHandler);
