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,在这种情况下,将会导致数据插入不成功,这里主要针对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:
代码语言:javascript复制<insert id="addParam" useGeneratedKeys="true" keyProperty="id" parameterType="com.pct.dotware.pams.entity.SysParam">
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}
)
</insert>
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:
代码语言:javascript复制@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;
