spring mvc 接收json、xml 数据格式，自动解析成对象

来源：互联网发布：三星clx3305清零软件编辑：程序博客网时间：2024/05/22 08:12

1、spring mve 接收json格式数据，

         @RequestMapping(value="/jsonPrase",headers = {"content-type=application/json","content-type=application/xml"})
        @ResponseBody
        public Object addUser(@RequestBody MsgTip tip) {

           try {
               System.out.println("add test ..............");
               System.out.println(tip.getMsg() + " == " + tip.getResult());
       } catch (Exception e) {
           e.printStackTrace();
       }
            return new HashMap<String, String>().put("success", "true");
        }
上面红色部分表示，请求的content-type是上面的两个时才能访问该方法，否则会报415

发送的数据："{\"result\":\"fasle\",\"userId\":null,\"msg\":\"请传入合法的op参数\",\"sightId\":null,\"pathId\":null}"

MsgTip 字段

   private String result;
   private Long userId;
   private String msg;
   private Long sightId;
   private Long pathId;

2、spring mvc接收解析xml数据

与json的差不多在对应的实体类上加上相应的xml注解，

    @XmlRootElement(name="tips")
   public class MsgTip {

   private String result;
   private Long userId;
   private String msg;
   private Long sightId;
   private Long pathId;

.......

测试类如下：

public static void testPost(String urlStr) {
       try {

           String xmlInfo = getXmlInfo();
           SimpleDateFormat format = new SimpleDateFormat(
                   "yyyy-MM-dd hh:mm:ss");
           System.out.println(format.format(new Date()) + "---发送信息开始。");

           System.out.println("xmlInfo=" + xmlInfo);

           URL url = new URL(urlStr);
           URLConnection conn = url.openConnection();
           conn.setRequestProperty("Pragma:", "no-cache");
           conn.setRequestProperty("Cache-Control", "no-cache");
           conn.setRequestProperty("Content-Type", "application/xml"); //如果是json数据把xml 改为json
           conn.setDoOutput(true);
           OutputStreamWriter out = new OutputStreamWriter(
                   conn.getOutputStream());
           out.write(new String(xmlInfo.getBytes("utf-8")));
           out.flush();
           out.close();

           BufferedReader read = new BufferedReader(new InputStreamReader(
                   conn.getInputStream()));
           String str = read.readLine();
           while (null != str) {
               System.out.println(str);
               str = read.readLine();
           }
           read.close();
           // ReceiveWeixinMsg recemsg = (ReceiveWeixinMsg) new
           // ParseXmlUtil().parseXmlFromObj(ReceiveWeixinMsg.class,
           // conn.getInputStream(), "xml", null);
           // System.out.println("接受信息为："+recemsg.getContent());
           System.out.println(format.format(new Date()) + "---接受结束。");
       } catch (MalformedURLException e) {
           e.printStackTrace();
       } catch (IOException e) {
           e.printStackTrace();
       } catch (Exception e) {
           e.printStackTrace();
       }
   }
