spring-data-redis set > 0 always execute "SELECT" before any command

spring boot version : 1.5.7.RELEASE

properties :
`spring.redis.database=3`

code :
```java
HashOperations<String, String, String> hashOperations = redisTemplate.opsForHash();
Map<String, String> map = hashOperations.entries("2330");
```

redis monitor :
```
"SELECT" "3"
"HGETALL" "1234"
"SELECT" "0"
```

it should be only this, isn't it?
````
"HGETALL" "1234"
````
