我在带有Redis的springboot2.0中使用@cacheable。我已将RedisCacheManager配置如下：

@Bean
public RedisCacheManager redisCacheManager(RedisConnectionFactory connectionFactory) {

    RedisCacheWriter redisCacheWriter = RedisCacheWriter.lockingRedisCacheWriter(connectionFactory);
    SerializationPair<Object> valueSerializationPair = RedisSerializationContext.SerializationPair
            .fromSerializer(new GenericJackson2JsonRedisSerializer());
    RedisCacheConfiguration cacheConfiguration = RedisCacheConfiguration.defaultCacheConfig();
    cacheConfiguration = cacheConfiguration.serializeValuesWith(valueSerializationPair);
    cacheConfiguration = cacheConfiguration.prefixKeysWith("myPrefix");
    cacheConfiguration = cacheConfiguration.entryTtl(Duration.ofSeconds(30));

    RedisCacheManager redisCacheManager = new RedisCacheManager(redisCacheWriter, cacheConfiguration);
    return redisCacheManager;
}

但这使所有密钥的ttl变为30秒，如何为每个具有不同缓存名称的redis缓存配置不同的ttl？
