Springboot -data-redis中 對於java1.8的LocalDate 序列化問題

報錯：org.springframework.data.redis.serializer.SerializationException: Could not read JSON: Expected array or string.

解決方案：

redis配置：

@Bean
public RedisCacheManager cacheManager(RedisConnectionFactory connectionFactory) {
    //默認1
    RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
            .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(keySerializer()))
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(valueSerializer()))
            .disableCachingNullValues();

    RedisCacheManager redisCacheManager = RedisCacheManager.builder(connectionFactory)
            .cacheDefaults(config)
            .transactionAware()
            .build();

    return redisCacheManager;
}

@Bean(name = "redisTemplate")
public RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
    RedisTemplate<String,Object> redisTemplate = new RedisTemplate<>();
    redisTemplate.setConnectionFactory(redisConnectionFactory);

    redisTemplate.setKeySerializer(new StringRedisSerializer());
    redisTemplate.setHashKeySerializer(new StringRedisSerializer());
    redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
    redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());

    return redisTemplate;
}

2.添加依賴

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.datatype/jackson-datatype-jsr310 -->
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

3.日期屬性加上註解：

@JsonDeserialize(using = LocalDateDeserializer.class)
@JsonSerialize(using = LocalDateSerializer.class)
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd")
private LocalDate createDate;

OK！！！
