具体问题在这

org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisException: Could not get a resource from the pool
Caused by: redis.clients.jedis.exceptions.JedisException: Could not get a resource from the pool
Caused by: java.util.NoSuchElementException: Unable to validate object

总体来看就是redis没有开启的原因，但是我的redis是开启的，无论是redis客户端连接，或者代码测试连接，或者RedisDesktopManager连接都正常。redis的配置文件中也不存在空格等符号，就是一直保错。

最后自查后发现，是代码通过Maven重新编译后，编译后的代码，redis资源文件中的redis地址变成了一个另外的地址，原本代码写的是127.0.0.1编译之后变了。不知道什么原因。编译后的代码，地址手动修改成127.0.0.1后，就可以成功启动了。
