MyBatis连接MySQL8.0.20报错No suitable driver found for jdbc:mysql//localhost:3306/mybatis?serverTimezone

最近这个bug困扰了我两天，上网一直找不到答案，一直提示我没有合适的驱动去加载，起初我还以为是不是我的数据库版本太高了，要不要考虑换个低一点的版本。报错具体如下：

Exception in thread "main" org.apache.ibatis.exceptions.PersistenceException:

在Database下测试连接数据库显示是正常的，没有问题的

最后我重新一个一个代码的去检查一遍，最后发现，我真的是被自己蠢哭了，最后查找到的错误是因为一个“ ：”的问题：
错误写法：

<property name="url" value="jdbc:mysql//localhost:3306/mybatis?serverTimezone=UTC&amp;characterEncoding=utf-8"/>

正确写法：（注意冒号）

<property name="url" value="jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC&amp;characterEncoding=utf-8"/>

算是一个教训，也是一个no suitable driver found for jdbc的一个解决汇总,也让我以后会更注意这些细节了。
