UserMapper.java 文件：

package com.my.mapper;

import com.my.entity.UserEntity;
import org.apache.ibatis.annotations.*;  
import org.springframework.stereotype.Component; 
import java.util.List;  
// @Mapper

public interface UserMapper {
    
        @Select("SELECT * FROM users")
        // @Results({
        //     @Result(property = "userSex",  column = "user_sex", javaType = UserSexEnum.class),
        //     @Result(property = "nickName", column = "nick_name")
        // })
        List<UserEntity> getAll();
    
        @Select("SELECT * FROM users WHERE id = #{id}")
        // @Results({
        //     @Result(property = "userSex",  column = "user_sex", javaType = UserSexEnum.class),
        //     @Result(property = "nickName", column = "nick_name")
        // })
        UserEntity getOne(Long id);
    
        @Insert("INSERT INTO users(id,namge,age) VALUES(#{id}, #{name}, #{age})")
        void insert(UserEntity user);
    
        @Update("UPDATE users SET age=#{age},name=#{name} WHERE id =#{id}")
        void update(UserEntity user);
    
        @Delete("DELETE FROM users WHERE id =#{id}")
        void delete(Long id);
    
    }

我在 GitHub 上下載了幾個 Spring Boot 使用 Mybatis 的 demo,但運行后都報類似的錯誤，請問為什么？

補充：
UserMapper.java 文件中：
如果把：import org.apache.ibatis.annotations.*;
改成：
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Insert:
..
就會報import 的錯，這是不是意味著import org.apache.ibatis.annotations 這個包存在，但其中并不存在Select和Insert .. 類？這可能嗎？
