额外引入jar

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

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<HttpMessageConverter<?>> 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);
    }

完结！
