工程下mapper.xml和mapper.java都存在切名称都对应
我习惯将mapper的xml和java都放在
中的同一目录下
网上看了各种办法均失败
1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE mapper 3 PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> 5 <mapper namespace="mapper"> 6 <select id="findUserByIdMapper" parameterType="int" resultType="ssm.po.User"> 7 select *from user where id=#{id} 8 </select> 9 </mapper>
这是改之前的代码，问题出在<mapper namespace="mapper"> 原来mapper代理开发的xml文件中namespace不能乱写，必须用对应mapper.java的全路径，也就是Ctrl要点的进去.
因为用的是Maven构建，在pom.xml的<build></build>标签中添加如下代码即可
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
问题解决！
