1 解析Xml

1.1 新增專案依賴

　　　　 <!-- 解析Xml -->
        <dependency>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
            <version>1.6.1</version>
        </dependency>

1.2 返回的Xml使用字串換行

String returnMsg = "<?xml version=\"1.0\" encoding=\"gb2312\"?>" +
                "<Result xmlns=\"https:www.youyoushop.work\">" +
                "<row resultcount=\"1\">" +
                "<userId>001</userId>" +
                "<usersName>張三</usersName>" +
                "<userAge>22</userAge>" +
                "</row>" +
                "<row resultcount=\"2\">" +
                "<userId>002</userId>" +
                "<usersName>李四</usersName>" +
                "<userAge>33</userAge>" +
                "</row>" +
                "</Result>";

@Test
    public void test1() {
        String returnMsg = "<?xml version=\"1.0\" encoding=\"gb2312\"?>" +
                "<Result xmlns=\"https:www.youyoushop.work\">" +
                "<row resultcount=\"1\">" +
                "<userId>001</userId>" +

                "</row>" +
                "<row resultcount=\"2\">" +
                "<userId>002</userId>" +
                "<usersName>李四</usersName>" +
                "<userAge>33</userAge>" +
                "</row>" +
                "</Result>";

        try {
            Document doc = DocumentHelper.parseText(returnMsg);
            Element roots = doc.getRootElement();
//            System.out.println("根節點 = [" + roots.getName() + "]");
//            System.out.println("內容：" + roots.getText());
            Iterator elements = roots.elementIterator();
            while (elements.hasNext()) {
                Element child = (Element) elements.next();
                //System.out.println("節點名稱 = [" + child.getName() + "]"+"節點內容："+child.getText());
                List subElements = child.elements();

                List<Map<String, Object>> treeMapList = new ArrayList<>();

                for (int i = 0; i < subElements.size(); i++) {
                    Map<String, Object> mapData = new HashedMap();
                    Element subChild = (Element) subElements.get(i);
                    mapData.put(subChild.getName(), subChild.getText());
                    treeMapList.add(mapData);
                    //System.out.println("子節點名稱："+subChild.getName()+";子節點內容："+subChild.getText());
                }
                System.out.println(treeMapList);
            }
        } catch (DocumentException e) {
            e.printStackTrace();
        }
    }

1.3 返回的Xml沒有換行

String strXML = "<?xml version=\"1.0\" encoding=\"UTF-8\"?> <Notification xmlns=\"https://netdist.youyoushop.work\"> <userId>7474741</userId> <userName>不服？咋滴</userName> <userAge>88</userAge> <Message>{\"jobId\":\"666888\",\"requestId\":\"639D1D03-1557-4AD7-9AD7-691F02834516\",\"state\":\"Success\"}</Message> </Notification>";
