LocalDate Serialization：date as array？

Question

我使用Java 11，并希望将LocalDate / LocalDateTime序列化/反序列化为String。好的。我添加了依赖性：

    <dependency>
        <groupId>com.fasterxml.jackson.datatype</groupId>
        <artifactId>jackson-datatype-jsr310</artifactId>
        <version>${jackson.version}</version>
    </dependency>

和模块：

@Bean
public ObjectMapper objectMapper() {
    return new ObjectMapper()
            .registerModule(new JavaTimeModule())
            .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
            .enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY);
}

当我向应用程序发送日期时，它会正确反序列化：

{"profileId":12608,"birthDate":"2008-03-20","relativeType":"SON","cohabitants":true}

当我直接将objectMapper用作bean时，它也正确地序列化了：

{"code":"SUCCESS","id":868,"profileId":12608,"birthDate":"2008-03-20","relativeType":"SON","cohabitants":true}

但是当它与控制器序列化时，它将序列化为数组：

{"code":"SUCCESS","id":868,"profileId":12608,"birthDate":[2008,3,20],"relativeType":"SON","cohabitants":true}

问题是在控制器上的正文中反序列化日期。控制器是：

@PostMapping
public Relative create(@Validated(Validation.Create.class) @RequestBody Relative relative) {
    return service.create(relative);
}

Relative.class：

@Getter
@Setter
@ToString(callSuper = true)
@JsonInclude(JsonInclude.Include.NON_EMPTY)
public class Relative extends MortgageResponse {

    @Null(groups = Validation.Create.class)
    @NotNull(groups = Validation.Update.class)
    private Long id;

    @NotNull
    private Long profileId;

    private LocalDate birthDate;
    private RelativeType relativeType;
    private Boolean cohabitants;
}

请给我建议，有什么问题以及如何解决。

在您的birthDate或任何日期字段上添加@JsonFormat批注。
