mybatin-plus报错：无效的绑定语句(未找到)

照着敲的
这各种报错 估计是pom的导包有问题
或者有木有那位老哥有可以运行的源码看看
mybatis-plus
项目结构与源码

User实体类

@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("pw_userid")
public class User {
    @TableId(value = "User_id",type= IdType.AUTO)
    private Integer User_id;
    @TableField(value = "UserName")
    private String UserName;
    @TableField(value = "Password")
    private String Password;
}

mapper接口

//@Repository//代表持久层
@Mapper
public interface Usermapper extends BaseMapper<User> {
    //所有的CRUD都操作完成
}

@SpringBootTest
@MapperScan(value = {"com.example.mybatisplus.mapper"})
class MybatisPlusApplicationTests {
    @Autowired
    private Usermapper usermapper;
    @Test
    void contextLoads() {
        //查询所有用户
        List<User> users=usermapper.selectList(null);
//        users.forEach(System.out::println);
        System.out.println(users);
    }
}

主类

@SpringBootApplication
//@ComponentScan(basePackages = "com.example.mybatisplus.mapper")
@MapperScan(value = {"com.example.mybatisplus.mapper"})
public class MybatisPlusApplication {
    public static void main(String[] args) {
        SpringApplication.run(MybatisPlusApplication.class, args);
    }
}

给报错的测试类（xxxxTests）打个断点试下，看是不是启动执行到这个测试类，里面的bean对象（Usermapper）注入失败

调整mapper层和resource里面的xml的路径；
第一种：像这种无效的绑定语一般都是 mapper 层和你写 sql 的 xml 不是同一个级别的路径；
比如：你第一层 mapper 层有个第二层的 usermapper 的 package，而你的 xml 就直接在 resource 根目录下，就会找不到
第二种：就是你配置扫描 xml 的路径不对，如下图：

实体类上加 @TableName("表名称") 试试

应该是缺少jar包
mybatis-plus-boot-starter
mybatis-plus-annotation
mybatis-plus-extension
你看pom.xml是不是缺少哪个包

启动类添加@MapperScan

@MapperScan(value = {"com.example.mybatisplus.mapper"})
不应该是
@MapperScan(value = {com.example.sbcnm.mapper"})
吗？
