关于加入Mybatis之后测试报错的情况

笔者尝试了网上的各种方法，mapper映射也没问题，注解写的也没问题，最后败在了依赖冲突上，原因是用SpringBoot3.x.x 搭配了 MyBatis2.x.x 使用，谨以此文章告诫自己不要再犯这种低级错误。

已纠正：

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>3.0.4</version>
</dependency>

另：注意在启动类前加上 @MapperScan 注解

@MapperScan("com.coder.community.dao")

 原错误警告见下：
