是由于mysql驱动版本太低导致。

本人 jdk版本是1.8.0_211，mysql版本是8.0.17，mysql-connector-java版本是5.1.39，

后来把mysql-connector-java改为最新版mysql-connector-java-8.0.17.jar后，运行成功。

pom文件为：

    <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->

        <dependency>

            <groupId>mysql</groupId>

            <artifactId>mysql-connector-java</artifactId>

            <version>8.0.17</version>

        </dependency>
