Mybatis动态表字段更新

Mybatis动态表字段更新，主要通过$符号完成，如下示例：

@Data
public class FileVo {
    /**
     * id
     */
    private Long id;

    /**
     * 文件id
     */
    private String fileId;
}

@Mapper
@Repository
public interface FileMapper {

    int updateBizTable(FileVo fileVo);

    FileVo selectVoFromBizTableById(FileVo fileVo);
}

    <update id="updateBizTable">
        update ${tableName}
            set ${columnName} = #{fileId}
        where id = #{id}
    </update>

    <select id="selectVoFromBizTableById" resultType="FileVo">
        select
            id,
            ${columnName} as test,
            "${columnName}" as columnName,
            "${tableName}" as tableName
        from ${tableName}
            where id = #{id}
    </select>
