    List<book>ar=new ArrayList<>();
    @Test
    public void test1()throws Exception{
        //创建xml读取流SAXReader对象
        SAXReader sr=new SAXReader();
        //读取xml文件获取文档对象
        Document dc=sr.read("xml/books.xml");
        //获取根元素
        Element el=dc.getRootElement();
        List<Element> elements = el.elements("book");
        for(Element x:elements){
            //查找属性
            String id=x.attribute("sn").getValue();
            //查找内容
            String name=x.elementText("name");
            String auther=x.elementText("auther");
            double price=Double.parseDouble(x.elementText("price"));
            ar.add(new book(id,name,auther,price));
