关于SpringBoot集成RedisCache的序列化相关配置

记录一下在Spring Cache中集成Redis的相关序列化配置

• 可以继承CachingConfigurerSupport来进行扩展CacheManager和KeyGenerator相关组件

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {

    /**
     * 配置redis的value 序列化策略
     *
     * @return
     */
    @Bean
    public RedisCacheConfiguration redisCacheConfiguration() {
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        RedisCacheConfiguration configuration = RedisCacheConfiguration.defaultCacheConfig();
        configuration = configuration.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer)).entryTtl(Duration.ofDays(30));
        return configuration;
    }

    /**
     * 配置RedisTemplate序列化方式
     *
     * @param connectionFactory
     * @return
     */
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(connectionFactory);

        // 使用Jackson2JsonRedisSerialize替换默认序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 设置key和value的序列化规则
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();

        return redisTemplate;
    }
}
