二、解决方案：mysql-connector-java 版本更改

2.1：报错时版本

<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>5.1.37</scope>
</dependency>

2.2：更改后版本

<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope><version>8.0.13</version>
</dependency>
