在请求中发送JSON且不加反斜杠

Question

{
  "creditRiskData": "{\"externalQueryDate\":\"4018-11-23T19:13:19.392+03:00\"}",
  "identityTypeCode": "TTN",
  "identityValue": "9999999998"
}

这是我的请求，我可以在swagger中发送但没有反斜杠，但会出错。

从请求中获取消息后，我正在使用objectmapper解析JSON：

 private LocalDate getExternalQueryDate(String creditRiskData) throws IOException {

        return objectMapper.readValue(creditRiskData, CreditRiskDataDTO.class).getExternalQueryDate();

    }

这是要解析的类，以便能够将JSON转换为变量：

public class CreditRiskDataDTO {

    private LocalDate externalQueryDate;

    public LocalDate getExternalQueryDate() {
        return externalQueryDate;
    }

    public void setExternalQueryDate(LocalDate externalQueryDate) {
        this.externalQueryDate = externalQueryDate;
    }
}

从前端开始，javascript发送时没有反斜杠。像这样：

{
  "creditRiskData": "{"externalQueryDate":"4018-11-23T19:13:19.392+03:00"}",
  "identityTypeCode": "TTN",
  "identityValue": "9999999998"
}

但是挥舞着就会出现此错误：

"fault": {
    "objectErrors": [
      {
        "objectName": "",
        "message": "JSON parse error: Unexpected character ('e' (code 101)): was expecting comma to separate Object entries; nested exception is com.fasterxml.jackson.core.JsonParseException: Unexpected character ('e' (code 101)): was expecting comma to separate Object entries\n at [Source: (PushbackInputStream); line: 2, column: 25]"
      }

有什么办法解决这个问题？发送时没有反斜杠？

例如，当我从get method获取数据时，它的显示如下：

"{\"externalQueryDate\":\"5018-11-23\",

带反斜杠。但是在Mysql数据库中，它没有反斜杠。但是大张旗鼓的表演带有反斜杠。

得到：

 CreditRisk creditRisk = creditRiskDataRepository.findByOrganisationId(organisation.getId());


            return creditRisk != null ? creditRisk.getCreditRiskDataCodeBased() : null;

当我发送此邮件时：

   {
  "creditRiskData": {"externalQueryDate":"4018-11-23T19:13:19.392+03:00"},
  "identityTypeCode": "TTN",
  "identityValue": "9999999997"
}

它给出了错误

 "fieldErrors": [
      {
        "filterName": "creditRiskInformationCodeTermBasedRequest.identityTypeCode",
        "errorCode": "NotEmpty",
        "objectName": "creditRiskInformationCodeTermBasedRequest",
        "message": "must not be empty",
        "variables": [],
        "fieldName": "identityTypeCode"
      },
