解决spring中redistemplate不能用通配符keys查出相应Key的问题

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="connectionFactory" />
</bean>

<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="connectionFactory" />
</bean>

long start = System.currentTimeMillis();
 //需要匹配的key
 String patternKey = "pay:*";
 ScanOptions options = ScanOptions.scanOptions()
  //这里指定每次扫描key的数量(很多博客瞎说要指定Integer.MAX_VALUE，这样的话跟 keys有什么区别？)
  .count(10000)
  .match(patternKey).build();
 RedisSerializer<String> redisSerializer = (RedisSerializer<String>) redisTemplate.getKeySerializer();
 Cursor cursor = (Cursor) redisTemplate.executeWithStickyConnection(redisConnection -> new ConvertingCursor<>(redisConnection.scan(options), redisSerializer::deserialize));
 List<String> result = new ArrayList<>();
 while(cursor.hasNext()){
  result.add(cursor.next().toString());
 }
 //切记这里一定要关闭，否则会耗尽连接数。报Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisException: Could not get a 
 cursor.close();
 log.info("scan扫描共耗时：{} ms key数量：{}",System.currentTimeMillis()-start,result.size());
