java - 如何在 spring-data 2.0.x 中创建 RedisCacheManager

Question

我正在将我的应用程序从 spring boot 1.5.x 迁移到 2.0.x。我想保留 jedis，但我对 RedisCacheManager 的实例化有疑问。

现在构造函数签名是

RedisCacheManager(RedisCacheWriter cacheWriter, RedisCacheConfiguration defaultCacheConfiguration)

但在此之前:

RedisCacheManager(RedisOperations redisOperations)

我定义这个 bean 在范围内只有 RedisTemplate:

@Bean
public RedisCacheManager redisCacheManager(RedisTemplate redisTemplate) {
    HandleRedisCacheManager redisCacheManager = new HandleRedisCacheManager(redisTemplate);
    redisCacheManager.setUsePrefix(true);
    return redisCacheManager;
}

现在应该如何创建？

尝试下面的代码，它适用于 spring-boot 2.1.0.RELEASE

@Bean
public RedisCacheManager redisCacheManager(LettuceConnectionFactory lettuceConnectionFactory) {
    RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
            .disableCachingNullValues()
            .entryTtl(Duration.ofHours(1))
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer.json()));
    redisCacheConfiguration.usePrefix();

   return RedisCacheManager.RedisCacheManagerBuilder.fromConnectionFactory(lettuceConnectionFactory)
                    .cacheDefaults(redisCacheConfiguration).build();

}
