写在前面

　　由于数据库表字段名称设计不合理，导致与MySQL数据库关键字或者预留关键字一致，从而导致数据插入不成功，这里仅针对Mybatis和MybatisPlus提出对应的解决方案，仅供参考！

一、Mybatis中解决方案

1、针对XML文件，可以在冲突的字段名添加 ` ` ( 反单引号在键盘Esc键下面的那个，注意切换英文输入法 ) 引起来，如下所示：

insert into sys_param ( `key`, `value`, `status`, `create_by`, `create_time`, `remark` ) values（ #{item.key}, #{item.value}, #{item.status}, #{item.createBy}, #{item.createTime}, #{item.remark} ）

2、如果不想修改xml文件，也可针对实体类进行修改，可以通过添加@Column注解，如下所示：

@Column(name = "`key`") private String key;

针对Mybatis，以上两种任选其一即可。

二、MybatisPlus解决方案

对于MybatisPlus解决就很简单了，直接在实体类上添加 @TableField 注解，给上别名加上反单引号即可。如下所示：

@TableFiled(name = "`key`") private String key; 附录：

1、MySQL5.7版本关键字和保留字地址如下：https://dev.mysql.com/doc/refman/5.7/en/keywords.html#keywords-5-7-detailed-A

2、MySQL8.0版本关键字和保留字地址如下：https://dev.mysql.com/doc/refman/8.0/en/keywords.html#keywords-8-0-detailed-A

3、这里列出部分MySQL关键字，仅供参考：
