Unsatisfied dependency expressed through field baseMapper

• springboot 报错：Unsatisfied dependency expressed through field baseMapper

mapper类上已经添加了 @mapper注解但是仍然报错
错误原因：

// 在配置 MybatisPlusConfig 时 MapperScan 的路径写错
@Configuration
@EnableTransactionManagement
@MapperScan("com.chenjiayan.vueblog.mapper")
public class MybatisPlusConfig {
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        return paginationInterceptor;
    }
}

总结：
配置mapper时即使标注了@Mapper 注解，也要确保@MapperScan中的路径正确。
