SpringCache+Redis在Service层使用@Cacheable无效

Question

使用的是SpringBoot 1.5.8.RELEASE
配置文件

@Configuration
@Component
public class RedisConfig extends CachingConfigurerSupport {

    @Resource
    private RedisConfigProperties redisConfigProperties;

    @Bean
    public RedisConnectionFactory redisConnectionFactory(){
        JedisConnectionFactory factory = new JedisConnectionFactory();
        factory.setHostName(redisConfigProperties.getHost());
        factory.setPort(redisConfigProperties.getPort());
        if(redisConfigProperties.getPassword()!=null){
            factory.setPassword(redisConfigProperties.getPassword());
        }
        return factory;
    }

    @Bean
    public RedisTemplate<String,String> redisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate<String,String> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        template.afterPropertiesSet();
        setSerializer(template);
        return template;
    }

    @Bean
    public CacheManager cacheManager(RedisTemplate redisTemplate) {
        RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
        cacheManager.setDefaultExpiration(10);
        return cacheManager;
    }

    private void setSerializer(RedisTemplate<String, String> template) {
        Jackson2JsonRedisSerializer serializer
                = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        serializer.setObjectMapper(om);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(serializer);
    }

    @Override
    public KeyGenerator keyGenerator() {
        return (o, method, objects) -> {
            StringBuilder sb = new StringBuilder();
            sb.append(o.getClass().getName());
            sb.append(":");
            sb.append(method);
            for (Object object : objects) {
                sb.append(":");
                sb.append(object.toString());
            }
            return sb.toString();
        };
    }
}

pom中

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

有一点问题是，我在一个新建的DEMO项目中同样的配置都是可行的，但是在正式项目中就是不会进行缓存，请问是什么原因导致的？
