LocalDateTime的序列化与反序列化

数据库实体表时间类型使用LocalDateTime

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    //添加该注解使用json解析时为"yyyy-MM-dd HH:mm:ss"
    @JsonSerialize(using = LocalDateTimeSerializer.class)
    @TableField("UPDATED_TIME")
    private LocalDateTime updatedTime;

json解析yyyy-MM-dd HH:mm:ss字符串为LocalDateTime

 // 用来反序列化yyyy-MM-dd HH:mm:ss 的LocalDateTime
        JavaTimeModule module = new JavaTimeModule();
        LocalDateTimeDeserializer localDateTimeDeserializer = new LocalDateTimeDeserializer(
            DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
        module.addDeserializer(LocalDateTime.class, localDateTimeDeserializer);
      ObjectMapper jackson = Jackson2ObjectMapperBuilder.json()
            .modules(module)
            .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
            .build();

关于myBatis plus 无法解析LocalDateTime

//gradle添加依赖
// 解决LocalDateTime类型不兼容问题
    implementation 'org.mybatis:mybatis-typehandlers-jsr310:1.0.2'

ok，解决了
