我正在升级项目的版本，目前正在使用 jackson-databind-2.13.0 。但我注意到 ObjectMapper 的启用方法已被弃用。

他们说要像这样使用它。

@deprecated Since 2.13 use {@code JsonMapper.builder().enable(...)}

但我无法使用它。

下面是我的 ObjectMapper 实例创建代码。我该如何改变？

      @Bean(name = {"objectMapper"})
      @Primary
      ObjectMapper objectMapper() {
        return newObjectMapper();
      }

  public static ObjectMapper newObjectMapper() {
    ObjectMapper objectMapper =
        new ObjectMapper()
            .disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
            .configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false)
            .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
            .configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true)
            .setSerializationInclusion(JsonInclude.Include.NON_NULL)
            .enable(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES);
JavaTimeModule javaTimeModule = new JavaTimeModule();
javaTimeModule.addSerializer(OffsetDateTime.class, new OffsetDateTimeSerializer());
javaTimeModule.addDeserializer(OffsetDateTime.class, new OffsetDateTimeDeserializer());
javaTimeModule.addSerializer(LocalDate.class, new LocalDateSerializer());
javaTimeModule.addDeserializer(LocalDate.class, new LocalDateDeserializer());
objectMapper
    .registerModule(javaTimeModule)
    .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);

return objectMapper;

}

解决方案：

    ObjectMapper objectMapper = JsonMapper
    .builder()
    .enable(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES)
    .disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
    .configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false)
    .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, …
