postman提交json格式时间，不能反序列化为LocalDateTime?

postman提交的时间参数

"beginTime":"2022-12-26T9:40:00",
"endTime":"2022-12-30T23:40:00"

后端报错情况

实体类

 @TableField(exist = false)
    private LocalDateTime beginTime;
    private LocalDateTime endTime;

以SpringBoot为例

引入JSR-310的相关依赖

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

增加配置

spring.jackson.serialization.write-dates-as-timestamps=false

这样应该就可以正确序列化LoacalDateTime了
扩展：如果需要支持更多种的日期格式（非标准的），需要重新定义Jackson的ObjectMapper，并加入JSR310的相关序列化规则

  public static final String DEFAULT_DATETIME_MS_PATTERN = "yyyy-MM-dd HH:mm:ss.SSS";
  public static final String DEFAULT_DATETIME_PATTERN = "yyyy-MM-dd HH:mm:ss";
  public static final String DEFAULT_DATE_PATTERN = "yyyy-MM-dd";
  public static final String DEFAULT_TIME_PATTERN = "HH:mm:ss";
  public static final String ABSOLUTE_DATETIME_MS_PATTERN = "yyyyMMddHHmmssSSS";
  public static final String ABSOLUTE_DATETIME_PATTERN = "yyyyMMddHHmmss";
  public static final String ABSOLUTE_DATE_PATTERN = "yyyyMMdd";
  public static final String ABSOLUTE_TIME_PATTERN = "HHmmss";
  public static final String DATE_TIME_LENGTH_26 = "yyyy-MM-dd+HH:mm:ss.SSSSSS";

  static ObjectMapper configureObjectMapper(ObjectMapper objectMapper) {
    // Set Naming Strategy
    objectMapper.setPropertyNamingStrategy(PropertyNamingStrategy.LOWER_CAMEL_CASE);
    // Set Feature
    objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
    objectMapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);
    objectMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
    objectMapper.enable(MapperFeature.PROPAGATE_TRANSIENT_MARKER);
    objectMapper.enable(JsonReadFeature.ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER.mappedFeature());
    objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
    // Handle Java Time & JSR310
    registerJavaTime(objectMapper);
    return objectMapper;
  }
  /**
   * registerJavaTime
   *
   * <p>Handle Time Format to JSR310
   *
   * @author Created by ivan at 下午2:52 2020/1/10.
   */
  public static void registerJavaTime(ObjectMapper objectMapper) {
    // Handle Java Time
    objectMapper.registerModule(new JavaTimeModule());

    // Handle JSR310 Time
    SimpleModule jsr310Module = new SimpleModule();
    jsr310Module.addSerializer(
        LocalDateTime.class,
        new LocalDateTimeSerializer(
            DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_DATETIME_PATTERN)));
    jsr310Module.addSerializer(
        LocalDate.class,
        new LocalDateSerializer(
            DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_DATE_PATTERN)));
    jsr310Module.addSerializer(
        LocalTime.class,
        new LocalTimeSerializer(
            DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_TIME_PATTERN)));
    jsr310Module.addDeserializer(
        LocalDateTime.class,
        new LocalDateTimeDeserializer(
            DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_DATETIME_PATTERN)));
    jsr310Module.addDeserializer(
        LocalDate.class,
        new LocalDateDeserializer(
            DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_DATE_PATTERN)));
    jsr310Module.addDeserializer(
        LocalTime.class,
        new LocalTimeDeserializer(
            DateTimeFormatter.ofPattern(DateTimePatterns.DEFAULT_TIME_PATTERN)));
    objectMapper.registerModule(jsr310Module);
  }

最后通过配置Spring的HttpMessageConverters，替换掉原有的Jackson ObjectMapper。这样新的请求会根据配置的规则，进行格式判断，并进行转换。
