引入的jar
xml解析使用dom4j
<!--xml解析-->
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>1.6.1</version>
</dependency>
<dependency>
<groupId></groupId>
<artifactId>fastjson</artifactId>
<version>1.1.36</version>
</dependency>
1.创建xml转json工具类
package ;
import ;
import ;
import .;
import org.dom4j.*;
import ;
/**
* @ClassName XmlToJsonUtil
* @Author gxy
* @Desc xml转json
*/
public class XmlToJsonUtil {
private XmlToJsonUtil(){
}
/**
* xml转json
*
* @param xmlStr
* @return
* @throws DocumentException
*/
public static JSONObject xml2Json(String xmlStr) {
Document doc = null;
try {
doc = (xmlStr);
} catch (DocumentException e) {
();
}
JSONObject json = new JSONObject();
dom4j2Json((), json);
return json;
}
/**
* xml转json
*
* @param element
* @param json
*/
private static void dom4j2Json(Element element, JSONObject json) {
// 如果是属性
for (Object o : ()) {
Attribute attr = (Attribute) o;
if ((())) {
("@" + (), ());
}
}
List<Element> chdEl = ();
if (() && (())) {// 如果没有子元素,只有一个值
((), ());
}
for (Element e : chdEl) {// 有子元素
if (!().isEmpty()) {// 子元素也有子元素
JSONObject chdjson = new JSONObject();
dom4j2Json(e, chdjson);
Object o = (());
if (o != null) {
JSONArray jsona = null;
if (o instanceof JSONObject) {// 如果此元素已存在,则转为jsonArray
JSONObject jsono = (JSONObject) o;
(());
jsona = new JSONArray();
(jsono);
(chdjson);
}
if (o instanceof JSONArray) {
jsona = (JSONArray) o;
(chdjson);
}
((), jsona);
} else {
if (!()) {
((), chdjson);
}
}
} else {// 子元素没有子元素
for (Object o : ()) {
Attribute attr = (Attribute) o;
if ((())) {
("@" + (), ());
}
}
if (!().isEmpty()) {
((), ());
}
}
}
}
}
2.测试
xml文件

JSONObject jsonObject1 = XmlToJsonUtil.xml2Json(returnObj);

}3.结果

}复杂的xml也能转成功，很棒！！！
