Types

type Redis

type Redis struct {
	Client func() *redis.Client
}

func (*Redis) CacheWithString

func (r *Redis) CacheWithString(key string, output interface{}, expire time.Duration, fn func() (interface{}, bool)) error

从String类型的缓存中读取数据，如没则重新调用指定方法重新从数据库中读取并写入缓存

func (*Redis) HGetAll

func (r *Redis) HGetAll(key string) (result []interface{})

func (*Redis) HMDel

func (r *Redis) HMDel(key string, fields ...string) error

func (*Redis) HMSet

func (r *Redis) HMSet(key string, data map[string]interface{}) error

func (*Redis) NewRedis

func (r *Redis) NewRedis(rdc *types.RedisCollector, cli *types.RedisClient, f func() *redis.Options) (*redis.Client, error)

func (*Redis) NoDataExpiration

func (r *Redis) NoDataExpiration() time.Duration

数据不存在情况下，为防止缓存雪崩，随机返回一个30到60秒的有效时间
