**springboot项目，用了最新的mysql连接驱动，报错如下：**

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.

那么，如何解决呢？  
按照提示修改相应的配置文件即可，这是修改前的配置

# 数据源的配置
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    spring.datasource.username=root
    spring.datasource.password=root
    spring.datasource.url=jdbc:mysql://localhost:3306/shouhuan

这是修改之后的配置：注意看第一行

# 数据源的配置
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    spring.datasource.username=root
    spring.datasource.password=root
    spring.datasource.url=jdbc:mysql://localhost:3306/shouhuan

本来以为修改之后就没问题了，确实上面的问题是没有了，但是又出现了一个新的问题，报错如下：

java.sql.SQLException: The server time zone value 'ÖÐ¹ú±ê×¼Ê±¼ä' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

从提示可以看出，这个是系统时间错误，仍然是修改配置文件，如下：

spring.datasource.url=jdbc:mysql://localhost:3306/shouhuan?serverTimezone=GMT%2B8

在spring.datasource.url=jdbc:mysql://localhost:3306/shouhuan后面加上?serverTimezone=GMT%2B8即可启动成功。
