你得贴出相关代码才好分析

无效默认值

一般这种问题的原因都是缺失如下包

<dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.20</version>
    </dependency>
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.2.0</version>
    </dependency>

如果不缺失，请clean maven项目，并更新maven仓库，然后重新启动试试
