Workaround: Modify the dependent version of postgresql9.3 in the Pom file

<!--https://mvnrepository.com/artifact/org.postgresql/postgresql-        <dependency >            <groupId>org.postgresql</groupId>            <artifactId>postgresql</artifactId>            <version>9.3-1102-jdbc41</version>        </dependency>

I'm using the 9.3 version of PostgreSQL locally,

Download the corresponding dependency: Https://mvnrepository.com/artifact/org.postgresql/postgresql
