Reference documentation mentions HashOperations to be autowired

[imba-tjd]

https://docs.spring.io/spring-data/redis/reference/redis/hash-mappers.html

  @Autowired
  HashOperations<String, byte[], byte[]> hashOperations;

this won't work. There are some discussion about it.

• HashOperations not being autowired [DATAREDIS-8] #586
• https://stackoverflow.com/questions/44709092/redis-hashoperations-dependency-not-found

it turns out this works.

@Resource(name = "redisTemplate")
HashOperations<String, byte[], byte[]> hashOperations;

In the mean time, @Autowired @Qualifier("redisTemplate") fails. I don't konw why.
