解析XML请求(明文模式)

XML格式:

<xml>
 <ToUserName><![CDATA[toUser]]></ToUserName>
 <FromUserName><![CDATA[fromUser]]></FromUserName> 
 <CreateTime>1348831860</CreateTime>
 <MsgType><![CDATA[text]]></MsgType>
 <Content><![CDATA[this is a test]]></Content>
 <MsgId>1234567890123456</MsgId>
 </xml>

解析XML后,通过HashMap<String, String>保存。

导入dom4j-1.6.1.jar包

代码如下:

public static HashMap<String, String> parseXML(HttpServletRequest request) throws Exception {
    HashMap<String, String> map = new HashMap<String, String>();
 
    // 通过IO获得Document
    SAXReader reader = new SAXReader();
    Document doc = reader.read(request.getInputStream());
 
    // 得到xml的根节点
    Element root = doc.getRootElement();
    recursiveParseXML(root, map);
 
    return map;
}
 
public static void recursiveParseXML(Element root, HashMap<String, String> map) {
    // 得到根节点的子节点列表
    List<Element> elementList = root.elements();
 
    if (elementList.size() == 0) {
        map.put(root.getName(), root.getTextTrim());
    } else {
        for (Element e : elementList) {
            recursiveParseXML(e, map);
        }
    }
}
