redis失效

redis中的token失效失效可能出现的问题：

1、在postman测试时报 500

2、控制台：

### Error updating database.  Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: 
Could not get JDBC Connection; nested exception is java.sql.SQLException: 
HikariDataSource HikariDataSource (HikariPool-1) has been closed.
### Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: 
Could not get JDBC Connection; nested exception is java.sql.SQLException: 
HikariDataSource HikariDataSource (HikariPool-1) has been closed.

解决办法：重新获取redis消息，产生新的token
