Java 这个错误是什么'；org.springframework.http.converter.httpMessageNodeTableException:无法读取JSON:无法反序列化实例'；什么意思？

我正在尝试向我的服务器发送一个JSON数组。我的JSON数组如下所示

["{"sourceAccountNo":"555555555555555","sourceBankCode":"GLBBNPKA","destinationBankCode":"GLBBNPKA","destinationBankAccountNo":"123456789111111","amount":5000,"narrationOne":"txn4 by maker 1","uniqueId":"ESW-COR:1405507591784"}"]

public class BulkCorporatePaymentResponse implements Serializable {

    private static final long serialVersionUID = -2026566288888889L;
    List<CorporatePaymentResponse> paymentResponseList;

    public List<CorporatePaymentResponse> getPaymentResponseList() {
        return paymentResponseList;
    }

    public void setPaymentResponseList(List<CorporatePaymentResponse> paymentResponseList) {
        this.paymentResponseList = paymentResponseList;
    }
}


public class BulkCorporatePaymentRequest implements Serializable {

    private static final long serialVersionUID = -202656628880099889L;
    private List<CorporatePaymentRequest> paymentRequestlist;

    public List<CorporatePaymentRequest> getPaymentRequestlist() {
        return paymentRequestlist;
    }

    public void setPaymentRequestlist(List<CorporatePaymentRequest> paymentRequestlist) {
        this.paymentRequestlist = paymentRequestlist;
    }

}

对应的服务器端方法是：

   @ResponseBody
    @ResponseStatus(value = HttpStatus.OK)
    @RequestMapping(value = "/xxx", method = RequestMethod.POST)
    public ResponseEntity<BulkCorporatePaymentResponse> xxx(@RequestBody BulkCorporatePaymentRequest corporatePaymentRequestList) {
            BulkCorporatePaymentResponse response = null;
            try {
                response = corporateApi.processBulkFundTransfer(corporatePaymentRequestList);
            } catch (Exception e) {

            }
            return new ResponseEntity<BulkCorporatePaymentResponse>(response, HttpStatus.OK);
        }

每当我尝试将上面提到的json数组传递给我的服务器时，我都会得到以下异常

任何建议都会大有帮助

编辑更新（Mona Jalal）：我在向邮递员发送raspi IP时，在一个旁注中发现了这个错误，然后单击发送按钮：

144.92.129.230:8080/api/devices

{
  "timestamp": 1457494478717,
  "status": 400,
  "error": "Bad Request",
  "exception": "org.springframework.http.converter.HttpMessageNotReadableException",
  "message": "Required request body content is missing: org.springframework.web.method.HandlerMethod$HandlerMethodParameter@53cb13b3",
  "path": "/api/devices"
}

显然，JSON解析器无法解析JSON。 尝试在验证JSON时查看问题所在

正如其他人提到的，在初始方括号内有一组无关的引号

你必须去掉这些。如果转换仍然不起作用，那么在将JSON映射到对象时可能会遇到其他问题，但不要混淆这两个问题并将引号放回原处——这种方法不会有任何效果——首先需要有效的JSON，然后才能确保有效的JSON可以反序列化到预期的对象中

---

也许JSON反序列化的单元测试已经就绪？

。我想答案是一样的。@injecto我不认为答案是一样的。@DavidWallace我想我同意你的看法，你知道我为什么会犯这样的错误吗？我真的不知道。但我觉得你的JSON字符串有点奇怪。你确定那些未加修饰的双引号应该放在方括号内吗？你有的不是有效的JSON。

[

和

{

之间不应该有引号。
