CMD命令登录MYSQL

CMD命令登录MYSQL，查看mysql版本，我的是8.0.27

• win+r进入cmd

C:\Users\ws199>mysql -uroot -p
Enter password: ****

• 查看版本

mysql> select version()
    -> ;
+-----------+
| version() |
+-----------+
| 8.0.27    |
+-----------+
1 row in set (0.01 sec)

查看MySQL依赖

MySQL依赖导入高于自己本地的MySQL版本

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.30</version>
        </dependency>

mysql版本超过8.0

超过8.0版本的就要在com.mysql.jdbc.Driver加入cj

<property name="driver" value="com.mysql.cj.jdbc.Driver"/>

mysql版本低于8.0

<property name="driver" value="com.mysql.jdbc.Driver"/>
