*  问题描述：在使用mybatis-plus框架开发时，同时使用easyExcel技术，读取Excel并保存到数据库中时，出现如上错误。
 *  解决思考：
    
     *  分析：在上述报错信息中，我们关注下面四句输出信息

1.  三句话都有EduSubject，说明问题出现在该类
2.  其次， Cause: java.lang.IllegalArgumentException: argument type mismatch这一句看出来，参数类型不匹配，而且前面提到id属性不匹配，
3.  我们去查看id是否有问题

EduSubject类  
![在这里插入图片描述][2020100419575982.png_pic_center]EduSubject表  
![在这里插入图片描述][20201004195830329.png_pic_center]我们发现，由于我们数据库中采用的是19位字符表示，而且我们插入数据采用mybatis-plus框架的主键生成策略，但我们用错了主键生成策略。

*  **解决方法**：使用正确的主键生成策略
