我現(xiàn)在想獲取一個(gè)content-type=application/json的回調(diào)數(shù)據(jù)，奇怪的是我使用@RequestBody獲取不到數(shù)據(jù)，如下代碼所示 ：

@Data
public class BaiduDocNofityResponse {
    private String messageId;
    private String messageBody;
    private String notification;
    private String server;

    private String subscriptionName;
    private String version;
    private String signature;
}

@PostMapping("/doc/notify")
public void notify(@RequestBody BaiduDocNofityResponse response){
    log.info("百度上傳文檔的回調(diào)通知：");
    log.info(response.toString());//**這里根本沒有打印出數(shù)據(jù)**

}

但是如果換成下面這段代碼就能獲取到：

@PostMapping("/doc/notify")
public void notify(HttpServletRequest request) throws IOException {
    log.info("request content-type=" + request.getContentType());
    log.info("百度上傳文檔的回調(diào)通知：" + request.toString());
    InputStream is = request.getInputStream();
    String val = StreamUtil.inputStream2String(is, "UTF-8");
    log.info(val);//**這里能打印出數(shù)據(jù)**
}

有誰知道是什么原因嗎？
