spring-data-redis这个库使用起来为啥很麻烦, 一个类就得写一次序列化类, 我用错了??

Question

声明处理某个类型(BaseCurrentUser)的序列化类

    @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;
    }

在service类中使用

@Autowired
private RedisTemplate<String, BaseCurrentUser> currentUserRedisTemplate;

那么我每次添加一个类型的存储, 就得加一套@Bean??? 是这样嘛? 还是我不会用?
或者说不这么用, 只用他的StringRedisTemplate, 每次都用 fastjson 手动序列化

Answer 1

在.xml中配置redis（包括集群、序列化），在类中注入RedisTemplate，使用异步回调的方式操作redis（或者直接操作）

RedisTemplate

Answer 2

可以再xml中配置

    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="connectionFactory" />
        <!-- redisTemplate事务配置，默认是不开启事务支持 -->
        <!-- <property name="enableTransactionSupport" value="false" /> -->
        
        <!-- 序列化方式 key/hashKey采用StringRedisSerializer -->
        <property name="keySerializer">
            <bean
                class="org.springframework.data.redis.serializer.StringRedisSerializer" />
        </property>
        <property name="hashKeySerializer">
            <bean
                class="org.springframework.data.redis.serializer.StringRedisSerializer" />
        </property>
        <property name="valueSerializer">
            <bean
                class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
        </property>
        <property name="hashValueSerializer">
            <bean
                class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
        </property>
    </bean>
