request读流,判断不同的请求

xml

// 取得输入流的xml
        Document doc = getContentXml(request.getInputStream());
        if (doc == null) {
            return setRtnMsg(400,"IO Error");
        }
        Element root = doc.getRootElement();
//      HashMap<String, String> headElements = new HashMap<>();
        LinkedHashMap<String, String> headElements = new LinkedHashMap<>();
        // 取得xml的Head节点所有项目的名和值
        listHeadNodes(root, headElements);
        for (String key : headElements.keySet()) {
            // 不检查非必填项
            if ("service_id".equals(key) || "tenant_ref_no".equals(key)) {
            } else {
                // 必填项为空时返回错误
                if (headElements.get(key).isEmpty()) {
                    return setRtnMsg(449,key + " isEmpty");
                }
            }
        }
        headElements.remove("partner_sign");
        // 检查Head内容完整性
        String mymd5 = MD5Util.encodeCollection(headElements.values());
        String comingMd5 = root.element("Head").element("partner_sign").getText();
//      System.out.println("mymd5>>" + mymd5 + "<<" + root.element("Head").element("partner_sign").getText());
        if (mymd5.equalsIgnoreCase(comingMd5)) {
            ComingMessage msg = new ComingMessage(doc.asXML(),new Date().getTime());
            try {
                comingMessageMapper.insert(msg);
//              messageRepository.save(msg);
            } catch (Exception e) {
                return setRtnMsg(500,"save fail");
            }
        } else {
            return setRtnMsg(449,"ContentMD5 Unmatch.get:" + mymd5 + ":::partner_sign:" + comingMd5 + ":::" + doc.asXML());
        }

        return setRtnMsg(202,"Success");

json

BufferedReader br = new BufferedReader(new InputStreamReader(
                    (ServletInputStream) request.getInputStream()));
            String line = null;
            StringBuffer sb = new StringBuffer();
            while ((line = br.readLine()) != null) {
                sb.append(line);
            }
            String appMsg=sb.toString();

获取到了json字符串,然后就可以转bean了
