java 进行xml文档解析

这份是对于postman请求时候,进行对于报文解析

图一为报文发送的内容

引入相关依赖

<dependency>
			<groupId>dom4j</groupId>
			<artifactId>dom4j</artifactId>
			<version>1.6.1</version>
</dependency>

调用这个方法后,所有的尖括号的值都已经存在,直接使用map.get 获取对应的key即可获取相关的value,进行封装对象操作:

   
    private Map<String, String> getXml(HttpServletRequest request){
        //初始化map
        Map<String, String> map = new HashMap<>();
        
        try {
            //获取request  stream
            InputStream inputStream  = request.getInputStream();
            //解析xml
            SAXReader reader = new SAXReader();
            Document document = reader.read(inputStream);

            Element root = document.getRootElement();
            //获取head和body的xml
            List<Element> elementList = root.elements();
            for (Element e : elementList)
                map.put(e.getName(), e.getText());

            //获取head的元素
            Element head = elementList.get(0);
            List<Element> headList = head.elements();
            for (Element e : headList)
                map.put(e.getName(), e.getText());
            
            //获取body的元素在进行二次清洗
            Document bodydoc = DocumentHelper.parseText(StringEscapeUtils.unescapeXml(map.get("body")));
            
            Element body = bodydoc.getRootElement();
            List<Element> bodyList = body.elements();
            for (Element e : bodyList)
                map.put(e.getName(), e.getText());
            
            inputStream.close();
        }catch (Exception e){
            e.printStackTrace();
        }

        return map;
    }

获取所有的map的值

 public void postUserMsgText(HttpServletRequest request){
        Map<String, String> map = getXml(request);

        for (String key : map.keySet()){
            String s = map.get(key);
            System.out.println(key + " : --> "+s);
        }

    }
