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>
12.  
     
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
