要用到一个功能是把xml格式文件转成json格式的.网上找了很多都不太慢意就自已写了一个
不多说,贴原码:
public
class Utilities {
/**
* 转换一个xml格式的字符串到json格式
* @param xml xml格式的字符串
* @return 成功返回json 格式的字符串;失败反回null
*/
@SuppressWarnings("unchecked")
public String xml2
JSON(String xml){
JSONObject obj = new JSONObject();
try {
InputStream is = new ByteArrayInputStream(xml.getBytes("utf-8"));
SAXBuilder sb = new SAXBuilder();
Document doc = sb.build(is);
Element root = doc.getRootElement();
obj.put(root.getName(), iterateElement(root));
return obj.toString();
} catch (Exception e){
e.printStackTrace();
return null;
}
}
/**
* 转换一个xml格式的字符串到json格式
* @param file java.io.File实例是一个有效的xml文件
* @return 成功反回json 格式的字符串;失败反回null
*/
@SuppressWarnings("unchecked")
public String xml2JSON(File file){
JSONObject obj = new JSONObject();
try {
SAXBuilder sb = new SAXBuilder();
Document doc = sb.build(file);
Element root = doc.getRootElement();
obj.put(root.getName(), iterateElement(root));
return obj.toString();
} catch (Exception e){
e.printStackTrace();
return null;
}
}
/**
* 一个迭代方法
* @param element: org.jdom.Element
* @return java.util.Map 实例
*/
@SuppressWarnings("unchecked")
Map iterateElement(Element element){
List jiedian = element.getChildren();
Element et = null;
Map obj = new HashMap();
List list = null;
for (int i = 0; i < jiedian.size(); i++) {
list = new LinkedList();
et = (Element) jiedian.get(i);
if(et.getTextTrim().equals("")){
if(et.getChildren().size()==0)
continue;
if(obj.containsKey(et.getName())){
list = (List) obj.get(et.getName());
}
list.add(iterateElement(et));
obj.put(et.getName(),list);
}else{
if(obj.containsKey(et.getName())){
list = (List) obj.get(et.getName());
}
list.add(et.getTextTrim());
obj.put(et.getName() ,list);
}
}
return obj;
}
//测试
public static void main(String[] args) {
System.out.println(new Utilities().xml2JSON(
"<MapSet>"+
"<MapGroup id='Sheboygan'>"+
"<Map>"+
"<Type>MapGuideddddddd</Type>"+
"<SingleTile>true</SingleTile>"+
"<Extension>"+
"<ResourceId>ddd</ResourceId>"+

"</MapSet>"));
}
}
