报错代码

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

报错原因

编写SQL语句的时候，查询的数据库对应的表名称写错了，代码找不到对应的表，写成user了

改错方法

将数据库名称改成你数据库对应的表的名称
