我有以下EventDTO 类:

@AutoValue
@JsonDeserialize(builder = AutoValue_Event.Builder.class)
@JsonIgnoreProperties(ignoreUnknown = true)
public abstract class Event {

    public static Event.Builder builder() {
        return new AutoValue_Event.Builder();
    }

    public abstract UUID id();

    @NotNull
    public abstract Type type();

    @NotNull
    @JsonSerialize(using = LocalDateSerializer.class)
    @JsonDeserialize(using = LocalDateDeserializer.class)
    public abstract LocalDate date();

    @AutoValue.Builder
    public abstract static class Builder {

        @JsonProperty("id")
        public abstract Builder id(UUID id);

        @JsonProperty("type")
        public abstract Builder type(Type type);

        @JsonProperty("date")
        public abstract Builder date(LocalDate date);

   }
}

验证适用于type和属性,当有效负载不正确时date,Jackson 会按预期抛出一个。JsonMappingException不幸的是,返回的错误消息text/plain类似于: JsonMappingException: Can not construct instance of project.dto.AutoValue_Event$Builder, problem: Missing required properties: type

有没有办法处理这些验证错误并返回一个明确的 json 错误对象?

我发现这篇文章 可以捕获异常并返回显式 json,但我无法在反序列化失败的字段上映射自定义错误消息(我不想解析消息异常以了解哪个字段不正确)。任何想法?
