经过一番研究发现，我使用的mysql-connector-java.jar包版本是8.0.17

使用MySQL报错com.mysql.cj.jdbc.Driver和The server time zone value \

而我使用的数据库连接驱动却是com.mysql.jdbc.Driver

使用MySQL报错com.mysql.cj.jdbc.Driver和The server time zone value \

解决方法有两种：

第一种：改变数据库驱动连接和url

# 数据库驱动
jdbc.driver=com.mysql.cj.jdbc.Driver
# 数据库url
jdbc.url=jdbc:mysql://localhost:3306/essayManagement?serverTimezone=GMT%2B8

如果只将com.mysql.jdbc.Driver改成com.mysql.cj.jdbc.Driver，那么就会报如下错：

所以同时要在url后添加?serverTimezone=GMT%2B8

即

使用MySQL报错com.mysql.cj.jdbc.Driver和The server time zone value \

第二种解决方法

那么就降低mysql-connector-java.jar包的版本，在这里使用5.1.38版本。

使用MySQL报错com.mysql.cj.jdbc.Driver和The server time zone value \

同时连接数据库的配置仍是使用com.mysql.jdbc.Driver

使用MySQL报错com.mysql.cj.jdbc.Driver和The server time zone value \

这样就会成功，不会报错。
