--------------------

出现上述原因是由于在pom配置的mysql连接jar包与本机数据版本不一致导致，博主mysql版本为8.0.23，误将jar包导为8.0.21，出现上诉报错，改回来就好了。

以下是pom中引入依赖版本：

<dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>8.0.23</version>
            </dependency>
            <dependency>
                <groupId>com.alibaba</groupId>
                <artifactId>druid</artifactId>
                <version>1.1.10</version>
            </dependency>

当然此处报错是说是连接时区的问题，如按此方法没有解决，可以在url中的数据库后面加时区的限制代码，此处就不举例了~~~~·
