大家好，我得到错误如下，而从 Postman 的要求
org.springframework.core.codec.DecodingException: JSON decoding error: Could not resolve type id '4' as a subtype of com.myproject.onetoone.viewmodels.request.TopicGenerationRequest : known type ids = [GoalsGenerationRequest, TodoGenerationRequest, TopicGenerationRequest]; nested exception is com.fasterxml.jackson.databind.exc.InvalidTypeIdException: Could not resolve type id '4' as a subtype of com.myproject.onetoone.viewmodels.request.TopicGenerationRequest : known type ids = [GoalsGenerationRequest, TodoGenerationRequest, TopicGenerationRequest] at [Source: (io.netty.buffer.ByteBufInputStream); line: 2, column: 13]
我的父母类：

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "type")
@JsonSubTypes({
    @Type(value = GoalsGenerationRequest.class, name="GoalsGenerationRequest"),
    @Type(value = TodoGenerationRequest.class, name="TodoGenerationRequest")
})
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class TopicGenerationRequest {
      private int type;
}

字符串
子类GoalsGenerationRequest：

import com.myproject.onetoone.viewmodels.request.TopicGenerationRequest;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
import com.fasterxml.jackson.annotation.JsonTypeName;
import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;

import java.util.List;

@JsonTypeName("GoalsGenerationRequest")
@Getter

public class GoalsGenerationRequest extends TopicGenerationRequest {
    private List<Goal> goals;
}

子类TodoGenerationRequest：

@JsonTypeName("TodoGenerationRequest")
@Getter
@Setter
public class TodoGenerationRequest extends TopicGenerationRequest {

    @NotNull(message = "A valid UUID must be passed")
    private UUID ownerId;

    @NotBlank(message = "valid title should be added")
    private String title;

    private ZonedDateTime deadline;


}

名为Goal的GoalsGenerationRequest的子类：

@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor

public class Goal {
    private int type;
    private int id;
}

Postman 的要求如下：

{
    "type": 4,
    "goals": [
        {
            "type": 3,
            "id": 456
        },
        {
            "type": 3,
            "id": 454
        }
        ]
}

型
请求被Map的端点具有以下逻辑：

Mono<ProfileIdentity> profileIdentityMono = Utility.getUserPrincipal().map(UserPrincipal::getProfileID);
        Mono<TopicGenerationRequest>  generationRequest = serverRequest.bodyToMono(TopicGenerationRequest.class)
            .onErrorResume(castError -> Mono
                .error(new ClientErrorException(ErrorCodes.INVALID_REQUEST, "please provide valid json body")));

请帮忙：）
