使用dom4j解析xml文件，并轉(zhuǎn)出json格式

我這邊的需要就是講xml格式的soap的響應報文解析出來并返回給前端這個需求我本來是不會寫的然后找我?guī)煾笌臀覍懙模?/p>

我怕以后自己遇到同樣的問題，所以在這里記錄下來首先要準備的依賴

String xml = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" +

這是一個xml格式的soap的響應報文

現(xiàn)在的需求就是將這個報文解析出來，我這里使用的是dom4j解析

public static JsonObject xmlToJson(String xml) throws Exception{
        //創(chuàng)建jsonobject
        JsonObject object = new JsonObject();
        //創(chuàng)建JsonArray
        JsonArray array = new JsonArray();
        //將array添加到object中
        object.add("commands",array);
        //創(chuàng)建一個SAXReader閱讀器
        SAXReader reader = new SAXReader();
        //根據(jù)字符串構(gòu)建字節(jié)數(shù)組輸入流
        InputStream is = new ByteArrayInputStream(xml.getBytes());
        //用閱讀器讀取文檔對象
        Document document = reader.read(is);
        //獲取文檔對象的根節(jié)點
        log.info("開始解析soap報文");
        Element root = document.getRootElement();
        //遍歷子節(jié)點
        for (Iterator iterator = root.elementIterator(); iterator.hasNext(); ) {
            Element bodyElement = (Element) iterator.next();
            for (Iterator iterator1 = bodyElement.elementIterator(); iterator1.hasNext(); ) {
                Element askResponseElement = (Element) iterator1.next();
                for (Iterator iterator2 = askResponseElement.elementIterator(); iterator2.hasNext(); ) {
                    Element robotResponseElement = (Element) iterator2.next();
                    for (Iterator iterator3 = robotResponseElement.elementIterator(); iterator3.hasNext(); ) {
                        Element element = (Element) iterator3.next();
                        String name = element.getName();
                        if ("commands".equals(name)) {
                            JsonObject ele = new JsonObject();
                            array.add(ele);
                            JsonArray subArray = new JsonArray();
                            ele.add("args",subArray);
                            for (Iterator iterator4 = element.elementIterator(); iterator4.hasNext(); ) {
                                Element subElement = (Element) iterator4.next();
                                String subName = subElement.getName();
                                if ("args".equalsIgnoreCase(subName)){
                                    subArray.add(subElement.getStringValue());
                                }else {
                                    ele.addProperty(subName, subElement.getStringValue());
                                }
                                //  System.out.println(subElement.getName() + ":" + subElement.getStringValue());
                            }
                        } else {
                            object.addProperty(name, element.getStringValue());
                            // System.out.println(name + ":" + element.getStringValue());
                        }
                    }
                }
            }
        }
        log.info("json格式的報文={}",object);
        return object;
    }

解析出來的就是這樣的

    {
      "args": [
