Java xml--json格式互转

SAXReader reader = new SAXReader();
Document read = reader.read(new File("file/xml/are.xml"));

String asXML = read.asXML();

JSONObject object = XML.toJSONObject(asXML);
System.out.println(object.toString());

输出

{"ARE":{"peoples":{"person":[{"names":"per1","sex":"男","name":"张三","age":23},{"names":"per2","sex":"男","name":"李四","age":13},{"names":"per3","sex":"女","name":"丽丽","age":20}]}}}

JSONObject object = new JSONObject(json);
String string =""+ XML.toString(object);
System.out.println(string);

输出
