春のキャッシュ+は、ゴミ問題をRedisの

春のキャッシュ+は、最近の研究ではなく奇妙なRedisのキャッシュゴミ問題中に発見されたのRedis。シェア

使用redisCacheConfiguration。フォームが文字化けします

redisCacheConfiguration.serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()));
redisCacheConfiguration.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));

使用してください。チェーンをまったくゴミ問題はございません

RedisCacheConfiguration redisCacheConfiguration =
                RedisCacheConfiguration.defaultCacheConfig()
                        .prefixKeysWith("redis")
                        .entryTtl(Duration.ofSeconds(10))
                        .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()))
                        .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));

コードの問題

    @Bean
    public CacheManager redisCacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisCacheManager cacheManager = RedisCacheManager.builder(redisConnectionFactory)
                .cacheDefaults(defaultCacheConfig())
                .withInitialCacheConfigurations(singletonMap("predefined", defaultCacheConfig().disableCachingNullValues()))
                .transactionAware()
                .build();

        return cacheManager;
    }

    private RedisCacheConfiguration defaultCacheConfig() {
        //  TTL  Time To Live
        /*前缀
        * 过期时间
        * key序列化
        * value序列化
        * */
        RedisCacheConfiguration redisCacheConfiguration =
                RedisCacheConfiguration.defaultCacheConfig()
                        .prefixKeysWith("redis")
                        .entryTtl(Duration.ofSeconds(10));
        // 会乱码
        redisCacheConfiguration.serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()));
        redisCacheConfiguration.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));

        return redisCacheConfiguration;
    }

正しいコード

    @Bean
    public CacheManager redisCacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisCacheManager cacheManager = RedisCacheManager.builder(redisConnectionFactory)
                .cacheDefaults(defaultCacheConfig())
                .withInitialCacheConfigurations(singletonMap("predefined", defaultCacheConfig().disableCachingNullValues()))
                .transactionAware()
                .build();

        return cacheManager;
    }

    private RedisCacheConfiguration defaultCacheConfig() {
        //  TTL  Time To Live
        /*前缀
         * 过期时间
         * key序列化
         * value序列化
         * */
        RedisCacheConfiguration redisCacheConfiguration =
                RedisCacheConfiguration.defaultCacheConfig()
                        .prefixKeysWith("redis")
                        .entryTtl(Duration.ofSeconds(10))
                        .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()))
                        .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));

        return redisCacheConfiguration;
    }
