article 2025/3/10 18:49:11

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

把http://mybatis.org/dtd/mybatis-3-mapper.dtd 放在浏览器中；得到一个文件

文件名：mybatis-3-mapper.dtd

文件后缀名：dtd,

英文：Document Type Definition

中文：文档类型定义

mapper表示根节点，mybatis-3-mapper.dtd被定义出来的意义，用来验证<mapper>*****</mapper>中使用的节点的是不是符合规范用的。

综上所述，引入定义。
