springboot - Why is the spring-data-redis library so troublesome to use? You have to write a serialization class once for each class. Did I use it wrong??

Question

Declare a serialization class that handles a certain type (BaseCurrentUser)

    @Bean
    Jackson2JsonRedisSerializer<BaseCurrentUser> jackson2JsonRedisSerializer(ObjectMapper objectMapper) {
        Jackson2JsonRedisSerializer<BaseCurrentUser> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<BaseCurrentUser>(
                BaseCurrentUser.class);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
        return jackson2JsonRedisSerializer;
    }

    @Bean
    RedisTemplate<String, BaseCurrentUser> currentUserRedisTemplate(JedisConnectionFactory connectionFactory,
                                                                    Jackson2JsonRedisSerializer<BaseCurrentUser> jackson2JsonRedisSerializer) {
        RedisTemplate<String, BaseCurrentUser> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(connectionFactory);
        redisTemplate.setDefaultSerializer(jackson2JsonRedisSerializer);
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        redisTemplate.setKeySerializer(stringRedisSerializer);
        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        return redisTemplate;
    }

Used in service class

@Autowired
private RedisTemplate<String, BaseCurrentUser> currentUserRedisTemplate;

Then every time I add a type of storage, I have to add a set of @Bean??? Is that so? Or I don’t know how to use it?
Or I don’t use it this way, I only use its StringRedisTemplate, every time All are manually serialized using fastjson

Answer 1

Configure redis (including clustering and serialization) in .xml, inject RedisTemplate into the class, and use asynchronous callback to operate redis (or operate directly)

RedisTemplate
