Redis使用LocalDateTime報錯問題

SpringBoot整合Redis時，使用LocalDate以下報錯

org.springframework.data.redis.serializer.SerializationException: Could not read JSON: Cannot construct instance of `java.time.LocalDateTime` 
(no Creators, like default constructor, exist): no String-argument constructor/factory method to deserialize from String value ('2021-03-06T11:27:13')

 

原因在於 localDateTime 無法完成反序列化，這里有2種解決方法。

1、直接在字段上面加兩個注解即可

  
    @JsonDeserialize(using = LocalDateTimeDeserializer.class)
    @JsonSerialize(using = LocalDateTimeSerializer.class)
    private LocalDateTime createTime;

2、在 Redis 配置類加上如下代碼。

RedisConfig.java
