我直接将你的代码全盘覆盖取代我的代码,结果还是500报错,但是已经将username和password成功insert到数据表中去了,请问下面代码报错意思是什么?
{

"error": "Internal Server Error",
"exception": "org.springframework.data.redis.RedisConnectionFailureException",
"message": "Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool",
