当使用opsForValue() 存取String类型key,value情形
@Autowired private StringRedisTemplate redisTemplate;
当使用opsForValue() 存取String类型key,自定义对象value情形
@Autowired private RedisTemplate<String, Object> redisTemplate;
当使用hash结构时
@Autowired private RedisTemplate<String, Object> redisTemplate;
BoundHashOperations<String, Object, Object> ops = redisTemplate.boundHashOps("key1"); ops.put("key2",obj);
