缓存一致性与SpringCache

<dependency>

@Cachable默认的配置：

@EnableConfigurationProperties(CacheProperties.class)
@Configuration
@EnableCaching
public class MyCacheConfig {
    
    
    @Bean
    public RedisCacheConfiguration redisCacheConfiguration(CacheProperties cacheProperties) {
    
    

        CacheProperties.Redis redisProperties = cacheProperties.getRedis();
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig();
        //指定缓存序列化方式为json
        config = config.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));
        config = config.serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()));
        //设置配置文件中的各项配置，如过期时间
        if (redisProperties.getTimeToLive() != null) {
    
    
            config = config.entryTtl(redisProperties.getTimeToLive());
        }

        if (redisProperties.getKeyPrefix() != null) {
    
    
            config = config.prefixKeysWith(redisProperties.getKeyPrefix());
        }
        if (!redisProperties.isCacheNullValues()) {
    
    
            config = config.disableCachingNullValues();
        }
        if (!redisProperties.isUseKeyPrefix()) {
    
    
            config = config.disableKeyPrefix();
        }
        return config;
    }
}
