LocalDateTime格式化问题简单处理

1、额外引入jar

 		 <dependency>
            <groupId>com.fasterxml.jackson.datatypegroupId>
            <artifactId>jackson-datatype-jsr310artifactId>
         dependency>

2、配置springboot的web的出参和入参

private String pattern = "yyyy-MM-dd HH:mm:ss";

// 全局处理localdatetime格式化问题
@Override
public void extendMessageConverters(List> converters) {
    MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();

    //localDateTime格式化
    JavaTimeModule module = new JavaTimeModule();
    LocalDateTimeDeserializer dateTimeDeserializer = new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(pattern));
    LocalDateTimeSerializer dateTimeSerializer = new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(pattern));
    module.addDeserializer(LocalDateTime.class, dateTimeDeserializer);
    module.addSerializer(LocalDateTime.class, dateTimeSerializer);
    ObjectMapper objectMapper = Jackson2ObjectMapperBuilder.json().modules(module)
            .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS).build();

    //date时间格式化
    objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    objectMapper.setDateFormat(new SimpleDateFormat(pattern));

    // 设置格式化内容
    converter.setObjectMapper(objectMapper);
    converters.add(0, converter);
}

3、如果不是使用springbootd的，参照上面类似配置即可
完结！
