Content-Type: application/x-www-form-urlencoded

接受第三方的post過來的xml，如果沒有設置Content-Type: application/x-www-form-urlencoded。則可以通過流來解析
代碼如下

BufferedReader in= new BufferedReader(new InputStreamReader(httpServletRequest.getInputStream()));
            String s="";
            StringBuffer sb=new StringBuffer();
            while((s=in.readLine())!=null){
                sb.append(s);
                }
            // dom解析xml
            DocumentBuilderFactory buildFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder build = buildFactory.newDocumentBuilder();
            Document document = build.parse(httpServletRequest.getInputStream(),"utf-8");

            NodeList nodelist = document.getElementsByTagName("MO");
            for (int i = 0; i < nodelist.getLength(); i++) {
                longcodeArray.add(document.getElementsByTagName("LongCode").item(i).getFirstChild().getNodeValue().substring(1));
                messageArray.add(document.getElementsByTagName("Message").item(i).getFirstChild().getNodeValue());
            }

  

 

 

如果設置了Content-Type: application/x-www-form-urlencoded 則需要去parmmeterMap中間去取

List<String> longcodeArray=new ArrayList<String>();
        List<String> messageArray=new ArrayList<String>();
        try {
            CreateLog log = new CreateLog();
            HttpServletRequest httpServletRequest = this.getHttpServletRequest();
            String keyandValue="";
            String key="";
            String value="";
            Iterator<String> it=httpServletRequest.getParameterMap().keySet().iterator();
            while(it.hasNext()){
                key=it.next();
                value = ((Object[])(httpServletRequest.getParameterMap().get(key)))[0].toString();
                keyandValue=key+"="+value;
                System.out.println(key+"= "+value);
            }
            if(keyandValue!=null){
                //dom4j來解析xml字符串
                Document document=DocumentHelper.parseText(keyandValue.toString());
                Element root=document.getRootElement();
                List mo=root.elements("MO");
                for(int i=0;i<mo.size();i++){
                    Element longcode=((Element)mo.get(i)).element("LongCode");
                    Element message=((Element)mo.get(i)).element("Message");
                    longcodeArray.add(longcode.getText());
                    messageArray.add(message.getText());
                }


            }
