二：在eclipse中使用XML约束文件
将约束文件，插入到xml文件中，两种约束文件的插入位置是相同的
核心配置文件：
<?xml version="1.0" encoding="UTF-8"?> <!-- .DTD文件是xml格式文件的约束文件，它约束了该xml文件使用的标签以及标签之间的关系 --> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-config.dtd">
sql映射文件：
<?xml version="1.0" encoding="UTF-8"?> <!-- 该文件代表的是类和表的映射关系，关于表的sql语句等等写在这里 --> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-mapper.dtd">
三：集成到eclipse开发工具中
Window-> Preferences->XML->XML Catalog->Add
然后
key：写入 xml文件中 PUBLIC中的值
Location：选择dtd文件的实际物理位置
