Eclipse中引入MyBatis約束

約束檔案

解壓mybatis原始碼jar包，約束檔案在mybatis-3.4.0-sources\org\apache\ibatis\builder\xml目錄下

KEY

confi的key值

http://mybatis.org/dtd/mybatis-3-config.dtd

mapper的key值

http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd

在eclipse中配置

window->Preferences

搜尋xml->點選xml catalog->點選add按鈕,會彈出Add XML Catalog Element視窗->點選File System按鈕->選擇key的型別，並輸入key值->點選ok即可

最後一步，申請儲存並關閉
