controller:

```
@Autowiredprivate RedisTemplate RedisTemplate;@Autowiredprivate JedisConnectionFactory jedisConnectionFactory;@RequestMapping(value = "RedisDb", method = RequestMethod.GET, produces = "text/html;charset=UTF-8")@ResponseBodypublic String RedisDb(){//获取redis默认db1中的数据Object object = RedisTemplate.opsForValue().get("KW");System.out.println(object);//将db1切换到db0jedisConnectionFactory.setDatabase(0);Object object2 = RedisTemplate.opsForValue().get("CountAll");System.out.println(object2);return null;}
