Spring+SpringMVC+Mybatis整合
一．首先創建三個文件夾用戶存放Spring+SpringMVC+Mybatis，如下圖
Mybatis文件夾下的配置
1.config文件內容
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--配置指向mappe.xml的路徑-->
<mappers>
<mapper resource="mybatis/UserMapper.xml"/>
</mappers>
</configuration>
2.UserMapper.xml文件配置
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//er 3.0//EN"
"http://mybatimybatis.org//DTD Mapps.org/dtd/mybatis-3-mapper.dtd">
<!--指向Dao層-->
<mapper namespace="cn.yunhe.dao.UserMapper">
<!--用戶信息查詢-->
<select id="selectUser" parameterType="int" resultType="map">
select * from user where id = #{id}
</select>
</mapper>
Spring文件夾下的文件配置
3.Spring-mybatis.xml文件配置
<?xml version="1.0" encoding="UTF-8"?>

</beans>
4.Spring.xml文件配置
<?xml version="1.0" encoding="UTF-8"?>
