使用dom4j解析xml文件，并转出json格式
我这边的需要就是讲xml格式的soap的响应报文解析出来并返回给前端这个需求我本来是不会写的 然后找我师父帮我写的，
我怕以后自己遇到同样的问题，所以在这里记录下来首先要准备的依赖
<!--dom4j-->
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>1.6.1</version>
</dependency>String xml = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" +
" <soap:Body>\n" +
" <ns2:askResponse xmlns:ns2=\"http://www.eastrobot.cn/ws/AskService\" xmlns:ns3=\"http://www.eastrobot.cn/ws/RobotServiceEx\">\n" +
" <robotResponse>\n" +
" <commands>\n" +
" <args>ff8080816bf47a1b016c8f39b153000b</args>\n" +
" <args>ff8080816bf47a1b016c8f3a1c4d000e</args>\n" +
" <name>prop.categoryId</name>\n" +
" <state>0</state>\n" +
" </commands>\n" +
" <commands>\n" +
" <args>ff8080816bf47a1b016c8f3a1c4d000e</args>\n" +
" <name>prop.objectId</name>\n" +
" <state>0</state>\n" +
" </commands>\n" +
" <commands>\n" +
" <args>94654758cf484e249bc71b52d6291cba</args>\n" +
" <name>prop.sessionId</name>\n" +

" </robotResponse>\n" +
" </ns2:askResponse>\n" +
" </soap:Body>\n" +
"</soap:Envelope>";这是一个xml格式的soap的响应报文
现在的需求就是将这个报文解析出来，我这里使用的是dom4j解析
public static JsonObject xmlToJson(String xml) throws Exception{
//创建jsonobject
JsonObject object = new JsonObject();
//创建JsonArray
JsonArray array = new JsonArray();
//将array添加到object中
object.add("commands",array);
//创建一个SAXReader阅读器
SAXReader reader = new SAXReader();
//根据字符串构建字节数组输入流
InputStream is = new ByteArrayInputStream(xml.getBytes());
//用阅读器读取文档对象
Document document = reader.read(is);
//获取文档对象的根节点
log.info("开始解析soap报文");
Element root = document.getRootElement();
//遍历子节点
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格式的报文={}",object);
return object;
}解析出来的就是这样的
{
"commands": [
{
"args": [
"ff8080816bf47a1b016c8f39b153000b",
"ff8080816bf47a1b016c8f3a1c4d000e"
