本文详细介绍了如何使用Jackson库自定义LocalDateTime、LocalDate和LocalTime的序列化和反序列化处理，通过设置特定的日期时间格式，确保数据在转换过程中保持一致性和正确性。

/**
 * jackson的LocalDateTime序列化处理
 * @return

@Bean
public ObjectMapper objectMapper() {

    JavaTimeModule javaTimeModule = new JavaTimeModule();
    javaTimeModule.addDeserializer(LocalDateTime.class, new JSR310DateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
    javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
    javaTimeModule.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
    javaTimeModule.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
    javaTimeModule.addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern("HH:mm:ss")));
    javaTimeModule.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern("HH:mm:ss")));
    ObjectMapper om= Jackson2ObjectMapperBuilder.json().build();
    om.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);
    om.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    om.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
    om.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
    om.registerModule(new ParameterNamesModule());
    om.registerModule(new Jdk8Module());
    om.registerModule(javaTimeModule);
    return om;
}
