我使用openapi生成器maven-plugin在我的spring-boot应用程序中生成API模型

                            </typeMappings>
                            <importMappings>

                </executions>
            </plugin>
        </plugins>
    </build>
    <...>

模型中生成的LocalDate/LocalDateTime字段如下所示：

public class CreateClientEventRequestData {

  @JsonProperty("factDt")
  @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
  private LocalDateTime factDt;

  <...>

  public CreateClientEventRequestData factDt(LocalDateTime factDt) {
    this.factDt = factDt;
    return this;
  }

  @Valid 
  @Schema(name = "factDt", description = "дата и время мероприятия", required = false)
  public LocalDateTime getFactDt() {
    return factDt;
  }

  public void setFactDt(LocalDateTime factDt) {
    this.factDt = factDt;
  }

  <...>
}

当我在API中使用这个模型时，factDt像数组一样被序列化：

"data": {
    <...>,
    "factDt":[2022,11,11,20,18,34,71000000],
    <...>
}

我想得到的是

public class CreateClientEventRequestData {

  @JsonProperty("factDt")
  @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
  @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd.MM.yyyy HH:mm:ss")
  private LocalDateTime factDt;

  <...>
}

因此factDt像字符串一样序列化：

"data": {
    <...>,
    "factDt": "11.11.2022 20:18:34",
    <...>
}

如果没有设置@JsonFormat注释，则无法在spring-boot中设置默认序列化模式

我尝试了几个SO建议，但都不奏效，以下是我尝试的：

• 对LocalDate的注释被序列化为数组
• https://stackoverflow.com/a/53409514/8990391
• LocalDateTime以数组格式表示
• https://stackoverflow.com/a/63698586/8990391（尝试从所有配置中删除@EnableWebMVC）

即使使用这样的最小示例，设置日期格式也不起作用：

    public static void main(String[] args) throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.registerModule(new JavaTimeModule());
        objectMapper.setTimeZone(TimeZone.getDefault());
        objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
        objectMapper.setDateFormat(new SimpleDateFormat("dd.MM.yyyy HH:mm:ss"));

        System.out.println(
                // prints LocalDateTime in default ISO format and not in "dd.MM.yyyy HH:mm:ss" format...
                objectMapper.writeValueAsString(LocalDateTime.now())
        );
    }

所有这些都使得从swagger生成模型而不是在代码中实现它们的想法非常不足……

非常感谢你的帮助
