redisTemplate 根据下标选择指定的redis数据库

实现方式一

@Autowired
	RedisTemplate<String, ?> redisTemplate;
	
	@SuppressWarnings("resource")
	public Object slist() {
		
		JedisConnectionFactory connectionFactory = 
				(JedisConnectionFactory) redisTemplate.getConnectionFactory();
		connectionFactory.setDatabase(1);//选择1号数据库
		List<San> slist = new ArrayList<San>();
		//通过redis模板对象 获取操作列表的接口
		ListOperations forList = redisTemplate.opsForList();
		List<String> range = forList.range("slist", 0, -1);
		for (String object : range) {
			San s = JsonUtils.jsonToPojo(object, San.class);
			slist.add(s);
		}
		return slist;
	}

实现方式二

	@Repository
public class SanDao {
	//注入redis模板对象
	@Autowired
	RedisTemplate<String, ?> redisTemplate;
	//注入jedis连接工厂对象
	@Autowired
	JedisConnectionFactory jedisConnectionFactory;
	@SuppressWarnings("resource")
	public Object slist() {
		
		jedisConnectionFactory.setDatabase(1);//选择1号数据库
		
		List<San> slist = new ArrayList<San>();
		//通过redis模板对象 获取操作列表的接口
		ListOperations forList = redisTemplate.opsForList();
		List<String> range = forList.range("slist", 0, -1);
		for (String object : range) {
			San s = JsonUtils.jsonToPojo(object, San.class);
			slist.add(s);
		}
		return slist;
	}
