关于spring缓存的问题

Question

没有倒入下面的依赖

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

配置文件
spring.cache.type=redis
spring.cache.cache-names=openManage
spring.cache.redis.time-to-live=120s
spring.redis.host=116.62.167.64
配置类

@Configuration
public class RedisConfig {

    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

    @Bean
    public RedisCacheConfiguration redisCacheConfiguration() {
        //加载redis缓存的默认配置
        RedisCacheConfiguration configuration = RedisCacheConfiguration.defaultCacheConfig();
        configuration = configuration
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));
        return configuration;
    }

    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        // 配置redisTemplate
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        // 设置序列化
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);


        // key序列化
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        // value序列化
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // Hash key序列化
        //redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        // Hash value序列化
        //redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

}

在方法上使用@Cacheable("test")注解。这种方式用的是springcache缓存吗？

Answer 1

@Cacheable是springframework的cache组件，可以整合redis,ecahce，memcache等。springboot使用 @Cacheable注解，要在config中或者Application启动类中加@EnableCaching注解才会生效。
