resource下配置文件
Mybatis------Spring------SpringMVC
1：创建mybatis包
1.1创建mybatis-config.xml全局配置
----------------------------------------------------------------------------
<?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">
只需要配置驼峰命名
<configuration>
<setting>
<setting name="mapUnderscoreToCamelCase" value="true"/>
<settting>
<configuration>
----------------------------------------------------------------------------
1.2创建mappers包（可以有各对应mapper下的类，此处只创建一个）
----------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
//对应包扫描路径
<mapper namespace="cn.xlh.travel.mapper.UserMapper">
-----各类sql语句-----
<select id="queryUserByUserName" resultType="User">
select * from tab_user where username=#{username}
</select>
</mapper>
------------------------------------------------------------
2：创建spring包
2.1：创建applicationContext.xml全局配置文件
------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>

</beans>
--------------------------------------------------------
2.2:创建spring连接mybatis的配置文件applicationContext-mybatis.xml
