[requestPayload]的对象映射尝试将字段[requestPayload]解析为对象，但找到了具体的值

Question

我将JSON字符串作为对象存储在elasticsearch中，但是在下面得到异常，其中requestPayload是我们的JSON字符串体: requestPayload的对象映射试图将字段requestPayload解析为对象，但找到了一个具体的值

方法如下：

@Override
public PushBookingNotification save(PushBookingNotification pushBookingNotification) {
    log.debug("Request to save PushBookingNotification : {}", pushBookingNotification);
    PushBookingNotification result = pushBookingNotificationRepository.save(pushBookingNotification);
    pushBookingNotificationSearchRepository.save(result);
    return result;
}

如下=====所示的====实体

公共类PushBookingNotification实现了可序列化的{

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@NotNull
@Column(name = "ota_hotel_id", nullable = false)
private Long otaHotelId;

@Column(name = "hotel_name")
private String hotelName;

@NotNull
@Column(name = "reference_no", nullable = false)
private String referenceNo;

@NotNull
@Type(type = "jsonb")
@Column(name = "request_payload", columnDefinition = "jsonb", nullable = false)
@Field(type = FieldType.Object)
private String requestPayload;

// Getter和setter方法

Answer 1

为什么在字段requestPayload上有注释@ field (type = FieldType.Object)。也许试着去掉它，它可能会起作用。
