namespace 或The content of element type mapper must match EMPTY

必须为元素类型 "mapper" 声明属性 "namespace" 或The content of element type "mapper" must match "EMPTY"

 

1. <?xml version="1.0" encoding="UTF-8"?>
2. <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
3. <mapper namespace = "com.introduce.Modle.User2">
4. <resultMap type="com.introduce.Model.User2" id="user2ResultMap">
5. <result property="name" column="name" />
6. <result property="age" column="age" />
7. <result property="sex" column="sex" />
8. </resultMap>
9. <select id="getUser2" resultMap="user2ResultMap">
10. <![CDATA[select * from User2 where name=#{name}]]>
11. </select>
13. </mapper>

 

 

只需把<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">   

这行中的两处config  改成mapper即可
