The above reasons are due to the inconsistency between the mysql connection jar package configured in the pom and the local data version. The blogger’s mysql version is 8.0.23, and the jar package is mistakenly imported to 8.0.21. An appeal error occurs, just change it back.

The following is the dependency version introduced in pom:

        <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>

Of course, the error reported here refers to the connection time zone problem. If this method does not solve the problem, you can add the time zone restriction code after the database in the url. I will not give an example here~~~~·
