Springboot+Mybatis+Postgresql遇到的问题

mvn install时遇到异常信息：

解决方法：在pom文件中修改postgresql9.3对应的依赖版本

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

我本地使用的是9.3版的postgresql，

下载对应的依赖：https://mvnrepository.com/artifact/org.postgresql/postgresql
