配置RedisTemplate Bean:

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
    redisTemplate.setConnectionFactory(redisConnectionFactory);
    //首先解决key的序列化方式
    StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
    redisTemplate.setKeySerializer(stringRedisSerializer);
    //解决value的序列化方式
    Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
    ObjectMapper objectMapper = new ObjectMapper();
    //SimpleModule simpleModule = new SimpleModule();
    //objectMapper.registerModule(simpleModule);
    // 解决jackson2无法反序列化LocalDateTime的问题
    objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
    objectMapper.registerModule(new JavaTimeModule());

    objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
    jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
    redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
    return redisTemplate;
}
