public class Demo {
public static void main(String[] args) throws Exception {
String str = "{\"id_no\":\"342422198012001122\",\"mobile_no\":\"13666667789\",\"name\":\"\u5f90\u4e3d\"}";
JSONObject obj = new JSONObject(str); //\u5728\u8fd9\u91cc\u8f6c\u6362\u3002

@ResponseBody
public void updateInvestorApplyAccountNo(HttpServletRequest request,
HttpServletResponse response,
@RequestBody String requestBody) {
int num = 0;
String result = "";
//下面是把拿到的json字符串转成 json对象
JSONObject jsStr = JSONObject.parseObject(requestBody); //将字符串{“id”：1}
//int jsID = Integer.parseInt(jsStr.getString("id"));//获取id的值
/**
* json对象转换成java对象
*/
InvestorApplyModel stud = (InvestorApplyModel) JSONObject.toJavaObject(jsStr,InvestorApplyModel.class);
}
有几种方式 第一 把字符串存到一个javabean 在 Controller通过@ResponseBody 转换成 JSON
或者 拼接字符串的形式 拼接成 json格式
