Question

我是Spring Data Redis的新手。我已经使用了spring boot数据redis 2.0.3，如下所示（从我的gradle构建中）

compile('org.springframework.boot:spring-boot-starter-data-redis:2.0.3.RELEASE')
compile('io.lettuce:lettuce-core:5.1.3.RELEASE')

当我尝试创建create（PUT）或get（GET）时，在Redis Desktop manager中注意到，密钥创建在上述存储桶中，但存储在存储桶下的空白命名空间（文件夹）中。但是我只想在存储桶（名称空间）下创建缓存键，而不要在空白子文件夹（如另一个空的命名空间）中创建（文件夹-从Redis Desktop Manager中可以看到）

@Bean
LettuceConnectionFactory lettuceClientConfigurationConnectionFactory() {
    RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
    redisStandaloneConfiguration.setHostName(redisHostName);
    redisStandaloneConfiguration.setPort(redisPort);
    redisStandaloneConfiguration.setPassword(RedisPassword.of(redisAuth));
    redisStandaloneConfiguration.setDatabase(0);

    LettuceClientConfiguration.LettuceClientConfigurationBuilder lettuceClientConfiguration = LettuceClientConfiguration.builder();

    lettuceClientConfiguration.useSsl();

    LettuceConnectionFactory lettuceConFactory = new LettuceConnectionFactory(redisStandaloneConfiguration,
            lettuceClientConfiguration.build());

    return lettuceConFactory;
}

@Bean
public RedisCacheConfiguration cacheConfiguration() {
    RedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
    RedisSerializer stringRedisSerializer = new StringRedisSerializer();

    RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
            .disableCachingNullValues()
            .entryTtl(Duration.ofHours(1))
            .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(stringRedisSerializer))
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer));
    redisCacheConfiguration.usePrefix();
    return redisCacheConfiguration;
}

@Bean
@Primary
public CacheManager  initRedisCacheManager(LettuceConnectionFactory factory) {

    RedisCacheManager.RedisCacheManagerBuilder builder = RedisCacheManager
            .RedisCacheManagerBuilder.fromConnectionFactory(factory);
    builder.cacheDefaults(cacheConfiguration());
    builder.transactionAware();
    RedisCacheManager cacheManager = builder.build();
    cacheManager.afterPropertiesSet();
    return cacheManager;
}

我可以通过确保为每个缓存存储区设置prefixKyesWith来解决此问题，因此put和get操作会寻找正确的存储/读取位置。

/ ** *获取Redis缓存编写器 * @返回RedisCacheWriter * / @豆角，扁豆 RedisCacheWriter redisCacheWriter（）{ 返回RedisCacheWriter.lockingRedisCacheWriter（lettuceClientConfigurationConnectionFactory（））; }

/ ** *获取缓存管理器 * @返回CacheManager * / @豆角，扁豆 @主 CacheManager cacheManager（）{ RedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer（）; 映射cacheNamesConfigurationMap = new HashMap <>（）;

    // configure catch buckets with prefixKeysWith information
    cacheNamesConfigurationMap.put(CacheBucket.A, RedisCacheConfiguration.defaultCacheConfig().prefixKeysWith(CacheBucket.A+":")
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer)));
    cacheNamesConfigurationMap.put(CacheBucket.B, RedisCacheConfiguration.defaultCacheConfig().prefixKeysWith(CacheBucket.B+":")
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer)));
    cacheNamesConfigurationMap.put(CacheBucket.D, RedisCacheConfiguration.defaultCacheConfig().prefixKeysWith(CacheBucket.D+":")
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer)));
    cacheNamesConfigurationMap.put(CacheBucket.E, RedisCacheConfiguration.defaultCacheConfig().prefixKeysWith(CacheBucket.E+":")
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer)));
    cacheNamesConfigurationMap.put(CacheBucket.F, RedisCacheConfiguration.defaultCacheConfig().prefixKeysWith(CacheBucket.F+":")
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer)));

    RedisCacheManager cacheManager =  new RedisCacheManager(redisCacheWriter(), cacheConfiguration(), cacheNamesConfigurationMap);
    cacheManager.setTransactionAware(true);
    cacheManager.afterPropertiesSet();
    return cacheManager;
}

SpringData Redis 2.0.3在cacheManager上的LettuceConnectionFactory在提到的cachebucket下的空白命名空间（文件夹）中创建缓存键
